Union VFX on production-ready Gaussian splat crowds, fxguide, 2026
Every few months, a new technology captures the attention of the virtual production community. Sometimes those innovations become production standards. Others remain exciting experiments. The real value lies in understanding what they reveal about the direction of the industry.
A recent conversation on the fxpodcast with David Schneider from Union VFX offers exactly that kind of insight.
Rather than treating Gaussian splats as another visualisation technique, Union VFX has been exploring how they can become practical production assets for feature film crowds. Working alongside Clear Angle Studios and its new Volumetric Capture Rig (VCR), the team has developed a workflow that captures real performers as animated 4D Gaussian splats, allowing them to be relit, integrated into CG environments and directed within established visual effects pipelines.
For virtual production professionals, the technical achievement is impressive. For educators and emerging talent, the bigger story sits elsewhere.
Innovation Happens Through Collaboration
The workflow described in the podcast exists because specialists from different disciplines brought together complementary expertise.
- Clear Angle Studios contributes advanced volumetric capture technology.
- Union VFX develops production-ready visual effects pipelines.
- Machine learning supports reconstruction.
- Lighting, compositing and rendering teams refine how those assets behave inside complex shots.
- No single discipline owns the solution.
This reflects a broader trend across virtual production, where innovation increasingly comes from collaboration between organisations, departments and technical specialisms rather than isolated breakthroughs.
That same collaborative mindset sits at the heart of VPSN, where universities, researchers and industry partners work together to understand how production practices are evolving and how education can evolve alongside them.
The Pipeline Matters More Than the Tool
One of the most valuable lessons from this work is that the technology itself is only one part of the story.
Gaussian splats have attracted significant attention because of their realism, but production environments demand far more than visual fidelity. Assets must be stable across time, respond consistently to lighting, integrate with compositing workflows and remain art-directable throughout production.
The engineering effort described by Union VFX focuses on solving those production challenges rather than simply generating impressive demonstrations.
For students, this reinforces an important lesson.
Creative industries rarely reward knowledge of a single piece of software. They reward people who understand how information moves between departments, how different specialists collaborate, and how production challenges are solved collectively.
Those foundations remain valuable even as technologies continue to change.
What This Means for Education
As new workflows emerge, educational programmes face an ongoing challenge.
Teaching individual software packages will always be necessary, but software evolves rapidly. Production pipelines, communication skills and collaborative problem-solving have much longer lifespans.
Students entering the industry today are increasingly likely to work alongside machine learning specialists, technical artists, virtual production supervisors, capture technicians, compositors and software developers on the same production.
Understanding each discipline’s role, vocabulary and constraints becomes just as important as mastering individual creative tools.
Preparing learners for that environment means creating opportunities to experience multidisciplinary collaboration long before they graduate.
Looking Beyond the Technology
Whether Gaussian splat crowds become an industry standard remains to be seen.
The more immediate takeaway is that virtual production continues to expand beyond traditional boundaries. Capture technology, machine learning, visual effects, real-time rendering and filmmaking are becoming increasingly interconnected, creating workflows that would have been difficult to imagine only a few years ago.
For projects like VPSN, these developments reinforce the importance of maintaining close dialogue between education and industry. Every emerging workflow offers an opportunity to ask a broader question:
How do we prepare the next generation of creative professionals for technologies that are still evolving?
The answer is unlikely to be found in a single piece of software. It will come through curiosity, collaboration and a strong understanding of production fundamentals that enable graduates to adapt as the industry continues to change.
