Tech Update (July 2023)

Tracy Harwood Blog July 17, 2023 Leave a reply

This week, we’ve got a few things for you to add to your tools list and some info about things you’ll be keen to watch out for… but before you check those out, we share with you a showcase of Unreal’s MetaHuman and a rather creepy demo of tendons in Blender!

Showcase

This is a creative piece, made using Unreal’s MetaHuman, that will give you goosebumps – note the very detail of the facial animation and especially the whistfulness captured in eyes of the character. You could almost see this guy opening a bank account using facial recognition tech! The short, based on a poem by Mike Antic, is called Blue Dot and has been created by Epic’s 3Lateral team in collaboration with Serbian artist Radivoje Bukvic (released 15 June) –

In this uncanny valley special demo created in Blender, Chris Jones‘ shows a ‘throwaway WIP’ – its great but if this is modelled on someone’s actual hand, well, I don’t really want to know more…

Out Now

Reallusion has released free ZBrush and Character Creator plugins. Both are excellent tools for refining your animations, and the ability to link these together makes for exciting new possibilities for improving your workflow. Here’s the link to the downloads and here’s a video explainer –

The popular open world game, No Man’s Sky is now also available for Mac. This may or not make it more accessible to creators because, of course, most of the tools folks have are still only PC but nonetheless its a start!

Onwards and Upwards

Unity, in collaboration with Apple, has devised a Beta programe for creating ‘spatial experiences’, intended to support development of content for the Apple Vision Pro. You can sign up to participate here.

Unreal features a neat demo of its massively scalable procedural generation framework (PGC), which ships with version release 5.2. This looks great – the demo is called Electric Dreams, and also illustrates its amazing Substate system. Video link here –

Worth Waiting For

Blockbuster Inc., seemingly made in the mold of that well-known machinima creator studio released way back in 2005 called The Movies, has released a demo which is now on Steam (it is being developed by indie studio, Super Sly Fox). Here’s the link – the full release date is reported as being later this year.

We’re all eagerly awaiting Blender 4.0, right (due November 2023)? As part of the release, Grease Pencil 3.0 will be included in its 2D animation toolset, originally an annotation tool that has evolved to do quite a bit more. You can read the update on Blender’s develop blog here.

Report: Oberhausen International Short Film Festival 2023

Tracy Harwood Blog May 3, 2023 2 Comments

I was privileged to have been invited to Oberhausen International Short Film Festival (Germany, 26 April to 1 May) by Dr Lars Henrik Gass, Festival Director, Katharina Schroder, Theme Coordinator and the programme curators, Dmitry Frolov and Vladimir Nadein for the first programme of avant-garde and experimental machinima films at a major European film festival to take place.  I was also delighted to see machinima work, created by Alice Bucknell, featured on the programme magazine’s front cover too!  I was there, primarily, to participate in a panel discussion with Gemma Fantacci, one of the organisers of the Milan Machinima Film Festival, and two artist-curators from the US and Hong Kong respectively, Alice Bucknell and Ip Yuk-Yiu.

Programme

The programme, entitled Against Gravity, was themed to loosely represent a video-game/machinima creative experience, from Starting the Game, Holding the Controller, Crack the Code, Don’t Forget to Save, Opening the Map, Unlock the Real, Cosplay As…, and a retrospective of Phil Solomon’s work, called Interplay, a filmmaker whose turn to machinima in later life was the inspiration for the festival theme.  As one might expect, the organizers dive into each sub-theme to tease out their narrative through a selection of works across a span of 27 years of machinima practice.  Unfortunately, I didn’t arrive in time to see all the selections, but the ones I did see were very interesting. 

Image: Programme Cover (link to Festival programme here)

Many of the films were ones I had not previously seen – experimental films tend to be distributed in a different way to traditional machinima, using mostly artistic channels, and so often make their way directly to independent film theatres and galleries as a consequence.  This of course diverges from the traditional approach to machinima-making of community-shared content, through which debate and practices are openly discussed.  What was interesting with the presentation was the mix of older work with more recent pieces, effectively positioning machinima in a narrative of avant-garde practice and demonstrating experimental applications by artists/filmmakers for an audience that clearly had interest in the work if little experience of machinima or games specifically.  I got the distinct sense of the emergence of a new generation of machinima fans – both creators and audience – and also the sense there is demand for a new way to experience machinima on larger screens from this audience, especially with technological advancements that make quality of content higher resolution and approaches employed by artists accessible in the experimental tradition of film viewership.  

It was also interesting that the foundation of machinima was considered relevant to the presentation of avant-garde works both because its origins lie within 3D real-time games engines and also because the use of game as a creative matrix for storytelling beyond gameplay conveys subversion, virtuality and transcendence – all themes that resonate well with the experimental arts movement.  Drawing on Solomon, however, the rationale for including machinima was the transformation from analogue forms of film to digital, with all the nuances that brings – relating to the breadth of creative practices, methods of transferring work for exhibition, storage and also presentation to audiences.  What was interesting in this is that many at the festival seem to have little conception of either the term machinima, the game communities from which it emanates or its impacts on popular online culture.  Filmmakers selected appear to have forged their own practices, sometimes as multimedia artists, using games as found tools and environments.  Some were clearly also a little reticent about being associated with its background and origins, the taint of the M.com years, and probably alongside that the many issues the community has collectively faced in relation to the recognition of originality, ownership and authorship of works created.

Of the themed selections I saw, in Open the Map, the idea that games whet the appetite for utopian experiences was demonstrated through the selection of two films.  The first was a documentary about a group of queer teenagers living through the challenges of Covid by escaping into Minecraft to connect with each other in a virtual safe space they made their own.  The film, Tracing Utopia (2021), was directed by Nick Tyson and Catarina de Sousa, and was based on their observations of working with the teenagers over an extended period of time.  It highlighted well the essence of community and collaboration, something that has always been the heart of machinima.  The second was Alice Bucknell’s three-channel installation converted for the festival to a single channel, called The Martian Word for World is Mother (2022). This film was made in Unreal Engine and showed three different visualisations of Mars (the Green, the Blue and the Red), each being a post-human perspective on the future colonisation of the planet, drawing inspiration from popular sci-fi tropes on the interplay between ecological, economic and political ideologies.  These include Elon Musk (terraforming), Donna Harraway (Cyborg Manifesto), Ursula K Le Guin and Kim Stanley Robinson’s 2009 Mars trilogy, among others.  It is Bucknell’s Blue Mars that is shown on the front cover on the Oberhausen Film Festival programme, illustrating how multinational organizations convert permafrost into water for sale back to Earth – something she presents as a speculative near future. Not exactly a vision of utopia per se but her Green Mars was an interesting approach to reflecting on how the technologies used to exploit Mars in her Red and Blue versions may help Mars bring back to life its former natural habitat for its own end.  She includes a mystical (textual and aural) language that was created using Scottish Gaelic, Helene Smith’s invented Martian language and sounds of Arctic wind, created using a text-to-speech AI and the assistance of OpenAI’s GPT-3.  A fascinating creative process and captivating to watch and listen to.

In Unlock the Real, older films were used to position machinima through documentaries, for example Harun Farocki’s Parallel I (2014) showed how games have advanced in their representation of assets such as trees, clouds, water and fire from the earliest machine dashes in the 1980s, to squares of the early 1990s, to more modern mesh representations such as in GTA in the 2000s.  That reflective process of course, with recent developments in the representation of fluid, skin and movement dynamics integrated now into so many tools that creators use, whilst incomplete in Farocki’s work perfectly illustrated how games have focussed on advancing realism.  This was then followed by works that demonstrated aspects of even greater realism, from shape and form, to speed of movement (Benoit Paillé’s Hyper Timelapse GTAV, see below), to representation of human experiences and the interplay between virtual and real, and even the way that in-game corruptions of brands really don’t hide what they represent any more (Jacky Connolly’s Decent into Hell, 2021).  Indeed, Connolly’s clever interweaving of photographs and real film into the GTAV landscape was quite a trippy experience.  It is not often one sees that trajectory so clearly but Vladimir and Dmitry’s curation made it easy for less experienced machinima followers to make the connections between virtual game worlds, film and real-life experiences.

Benoit Paillé’s HYPER TIMELAPSE GTAV (CROSSROAD OF REALITIES) (available on Les Nuits Photo Festival Vimeo channel, released 30 Nov 2015) –

The Phil Solomon retrospective, themed Interplay, was equally fascinating, with introductory comments by Ip Yuk-Yiu and Lynne Sachs who both knew him personally.  Solomon was a key influencer in the US avant-garde film scene, and one of his early works had previously won an award at the Oberhausen Film Festival (Remains to be Seen, 1990 – a clip of which you can see on this Vimeo channel).  Vladimir and Dmitry selected two of his early photochemical 16mm films: The Secret Garden (1988) and Twilight Psalm II: ‘Walking Distance’ (1999).  These had a mesmerising depth to them apparently achieved by applying an emulsion to each frame and then transferring it using an optical reader.  They were juxtaposed with the subsequent selection of Solomon’s tribute following the passing of his lifelong friend, Mark LaPore, in a trilogy of machinima films made using GTA (San Andreas). The trilogy was called In Memoriam: Rehearsals for Retirement (2007), Last Days in a Lonely Place (2007) and Still Raining, Still Dreaming (2008). Interestingly, Yuk-Yiu commented that he never fully appreciated Solomon’s machinima work when it was released. This was primarily because he could not see a connection to his previous work yet the interplay was evidently between chemistry and code (analogue and digital) techniques as well as presence/absence represented by the virtual world.  However, the rather melancholic scenes in the machinimas, which seemed to somehow represent Solomon’s search for his friend through the glitches in the game world, may also have been connected through another film that Solomon made with LaPore in GTA, released just a few days before he died, called Crossroad (2005).

Panel Discussion

I really enjoyed the opportunity to participate in the panel discussion as well as the various follow-up chats with others visiting the event.  On the panel, each of us had very different experiences and perspectives of machinima, and we were asked some great questions about how we came to machinima, how we see it evolving and what its future will be. A question that emerged was at what point is the term machinima no longer relevant. From an avant-garde perspective, some questioned whether machinima’s history got in the way of framing their work.  Well, of course, many of us long-timers have had those discussions over the years but it was interesting to hear others discuss this too. I really liked how the critical reflection suggested that it is its adaptability in reflecting latest technological and game advancements as ‘machine cinema’ that keep it apart from other creative practices – an observation I like to think the pioneering Hugh Hancock would have been supportive of. 

Machinima is also clearly a good fit with the avant-garde scene, which of course is well reflected in Matteo Bittanti et al’s VRAL Patreon project, where you can find monthly film selections and interviews with creators. Matteo is also one of the founders of the Milan Machinima Film Festival, along with Gemma Fantacci, a student of game-related counter-culture, whom I had the pleasure of meeting in person for the first time in Oberhausen (although earlier this year we also chatted for the Digra Italia talks series).  Indeed, a number of the directors included in the machinima theme at Oberhausen were ones the Milan team have featured, as indeed have we on the CM podcast.

Another interesting audience question was also about the nature of 3D and its continual re-emergence in film, and how it differs in games. It was clear that with a primarily film-based audience, some struggled to appreciate the nature of 3D and realtime concepts that are so well understood in game worlds. Of course, anything rendered for a 2D screen immediately makes it difficult to imagine depth dimensions, or indeed the methods used to capture and edit scenes, for example using mod tools within 3D environments.  Part of the reason is the different uses of the term 3D: in-game experiences are a 2D illusion of a 3D representation rendered through a screen. 3D films in contrast are a fixed view perspective generated by overlaying stereoscopic views.  I’m sure they exist but, thinking about this, I don’t recall ever having seen a 3D stereoscopic machinima.  Nonetheless, the nature of machinima remains a challenging aspect to communicate and convey – as indeed do the differences in the experience one has when viewing the work in a publicly shared environment such as a cinema, gallery or arcade compared to desk-based screens, handheld or even hyper-personal VR screens.  For example, most machinimas we review on the CM podcast have never been intended for consumption on the ‘big’ screen and it certainly isn’t made using large format screens. This is something I recall thinking about at great length for the 2007 European Machinima Festival as well as the various showcases of works I’ve made over the intervening years, not least because detail is emphasized in ways that is never really experienced in a 3D game environment.  And even though many avant-garde works are intended for larger format screens, this aspect does not seem to be a particular focus of directors.  Thus, the 3D/2D transformation highlights another important yet completely unexplored and unappreciated aspect of machinima as avant-garde or experimental film, perhaps related to the closed distribution methods and consumption experience design strategies used as previously highlighted.

In sum, Oberhausen International Short Film Festival was a fascinating in-depth review of different avant-garde perspectives on machinima.  It was a real pleasure to have time to talk to some of the participants in the programme who made the journey from across the world to attend.  I was especially thrilled to see the baton for the development of a new appreciative community being picked up by Dmitry and Vladimir – the huge effort they had made in devising the programme, engaging with creators and connecting the dots across the generations of machinima and filmmaking traditions was outstanding, and evidenced in most of the theme sessions selling out.  I was really pleased to hear they are potentially going to be doing more of this in future and I’m certainly looking forward to catching up with them soon to hear their reflections and future plans too. 

And finally, something I haven’t experienced since I was a teenager was the beautiful plush setting of the cinema in which the programme took place, complete with red velvet curtains and projectors (when required) at the Lichtburg (meaning ‘fortress of light’) Filmpalast Gloria auditorium (see above). Oberhausen is the oldest German short film festival, founded in 1954, and one of the most significant for the development of production conditions in Germany.  In 1962, the Oberhausen Manifesto declaration by 26 filmmakers at the eighth festival is attributed with having created the basis for the success of New German Cinema worldwide.  I therefore thoroughly recommend finding the time to visit and support a future festival.

Quake 1: Ray Traced Mod by sultim_t (Dec 2022)

Ricky Grove Blog December 19, 2022 Leave a reply

Even the everyday gamer knows how much graphics technology has advanced over the last few years. The days of the old, pixelated textures on walls and rocks are long gone. So much so that gamers with more advanced skills have gone back to classic games like Doom and have re-coded them to include advanced graphic technology like high-definition textures and ray-traced rendering.

I’m not going to go into detail about ray tracing in this short article. You can find a complete explanation here. Essentially it has to do with how light is reproduced in a 3D game engine. Ray-traced rendering makes everything in a 3D scene look more realistic and believable. This is why adding ray tracing to games like Doom and now Quake is so exciting. The original blocky look to the game is gone. In its place is a more believable environment that adds so much to the atmosphere of horror in the game. This is perfect for those who want to go back and play the original game: it’s a better experience. It is also great for those first-time gamers who didn’t grow up with Doom or Quake.

Although certainly not at the same level of realism as modern games like Elden Ring, the new Quake mod is pretty damn good if you ask me. The sultim_t team deserves a standing ovation for their hard work.

You can download the Quake Ray Traced Mod by clicking the link. We also have a short trailer that sultim_t put on out the mod. The comments for the video are worth a read as well. Of course, you need to buy Quake from Steam in order to get started. The mod is free.


Projects Update (Nov 2022)

Tracy Harwood Blog November 14, 2022 1 Comment

This week, we take a look at some interesting projects we’ve found in our monthly search of the inter-web for all things machinima / virtual production / real-time. We bring you projects using Web3, made with a HUGE cast, mix virtual and real, and 2D and 3D animation styles

Crip Ya Enthusiasm by SnoopDogg (rel 16 Oct 2022)

Apart from the typical SnoopDogg lingo, which you either love or loathe, this is an interesting short made in Unreal Engine 5. It is not so much interesting because it is a music video by a self-confessed creative tech lover with a novel storytelling approach to putting his content out, but because it is being distrubted through Snoop’s new Web3 platform called Astro Project as a gamified experience or, to use his term, a ‘metaverse music video’. The characters used in the video have been made available on the platform’s marketplace as NFTs and other creators are being encouraged to create and share content through the platform to unlock exclusive content and hosted events. Anyone buying the characters can do anything they like with them, include them in their own creative works for example, using the blockchain tech embedded in their creation and distribution. So, whether you like the content or not, its the platform process used that is particularly interesting in this project.

As with all things NFTs, it is worth noting that really, its success is only as good as the marketing effort through which you can achieve decent audiences in order to manipulate the market parameters. Obviously SnoopDogg has an upper hand on this.

SAPIENS by Lukas Klosel (rel 7 July 2022)

This is a cinematic short about the impact on man on our planet. Its a very provocative film, which does include some disturbing scenes (so if you’re sensitive, you may want to miss watching this one). We’re not exactly sure what creative tools have been used in this one, and the description doesn’t say, but certainly there’s a fair amount of post-production as well as mixing of real and virtual content so there’s bound to have been some use of virtual production tools. We include it though because of the way it mixes virtual and real scenes, how it portrays its focal story through visual concepts (and lens focus) and clever use of sound design.

Sandstorm by Wailander (rel 13 May 2022)

A more traditional machinima made in Star Citizen, this has some great dynamics, played out by the 97 players involved in shooting the scenes included in the finished video. Its an incredibly complex set of scenes with many participants involved in portraying the details of the rather loosely defined plot. Its creative goal, however, wasn’t so much to tell a story as to bring together as many different players as it could. We certainly think it delivered on, drawing in organizations from five different countries (France, USA, Switzerland, Belgium, Germany) and portraying as accurately as it could how fighting unfolds in this expansive engine. The story is held together with a front end briefing against which they do periodic updates. The credits section alone is something to just take a look at. The final scene intimates a continuing saga and we look forward to seeing that and perhaps more of a story integrated into the fighting action too.

Roborovski by Rick Pearce (rel 2020)

Too sentimental for Ricky perhaps, but certainly not one for Nemo-loving children, this is short that mixes 2D and 3D animation styles very effectively. Made in Unreal Engine 4.21, primarily used in order to test the creative pipeline in the engine, the film won Flickerfest’s best animation award in 2020. It was made by Pearce’s Spectre Studio and funded by Screen Australia, so it is by no means a naive creative endeavour. The video is above in the title link, but here’s a behind the scenes look at the making of the film, which is particularly interesting too.

The Walker by AFK – The Webseries (Rel 5 Aug 2022)

Finally, this month, a revisit to a little bit of old-style fun made in Unreal Engine 5, invoking all those great memories of RVB Series 1 (Rooster Teeth, for those in the know). In this short, some incredibly well done Star Wars comedy voice-acting, told through the suits of the Empire’s Snow Troopers, located deep in the bowels of an ATAT. Enjoy!
