Houdini 22 is one of the biggest SideFX releases in years, a 30th-anniversary update that lands with native Gaussian Splatting, a refreshed interface, a maturing Karma renderer, and a huge expansion of Copernicus. We already tested the early beta releases on our own farm, and we're making a simple promise: within 24 hours of Houdini 22 releasing, you can render it on Drop & Render.
Quick answer: Drop & Render is an official SideFX partner that tested the early beta releases of Houdini 22, so our render farm is ready within 24 hours of release. You can submit Houdini 22 jobs straight from the HDA with one click, render Karma (CPU and XPU), Redshift, Arnold, Octane, V-Ray and Mantra, run PDG/TOPs graphs, and even offload the new Gaussian Splat training and rendering workloads to our farm. Frames write straight back to your drive, and every asset is scanned and remapped automatically.
What's new in Houdini 22
Houdini 22 was revealed in a sneak peek on 8 June 2026, launched at an event in London on 17 June, with the full keynote published on 22 June. SideFX skipped a 21.5 point release and jumped straight to a new major version, a signal of how much is packed inside. Here's what matters most for anyone rendering at scale.
Native 3D Gaussian Splatting
This is the marquee feature. Houdini 22 can create, edit, rig, animate, relight and render 3D Gaussian Splats natively. Splats can be reconstructed from photographic input or generated from your own rendered 3D scenes using a camera array, and, crucially, training is parallelised through PDG/TOPs. You can even convert volumetric elements like clouds and fireballs into storage-efficient splats. Relighting and final rendering happen inside Karma.
A more mature Karma
Karma continues its climb toward a production-grade renderer. Houdini 22 adds instanced mesh lights with per-instance control over colour and intensity, equiangular multi-importance sampling for cleaner point lights inside volumes, a native flake shader, and dedicated curvature and ambient-occlusion shading nodes, all riding on updated USD and MaterialX.
Copernicus goes big
Copernicus, Houdini's 2D/3D image framework, is one of the most heavily updated systems this release. Highlights include a full Paint 3D texturing package, Neural Cellular Automata for organic patterns that grow seamlessly across UV seams, a new ripple/adjacency VFX solver, and live Session Sync with Unreal. The terrain and heightfield toolset has also moved into Copernicus, with SideFX citing performance gains of up to 5×.
USD world building in Solaris
A new render-time scattering procedural runs Houdini Engine inside Hydra, so a USD scene stays lightweight even with hundreds of thousands of instances. Camera-frustum culling saves memory, ambient-occlusion masking places instances intelligently, and the Edit LOP gains physics-based, RBD-driven placement.
Characters, foundations and AI
KineFX and APEX pick up IK limits, set-driven keys and nested clips in Motion Mixer, plus retargeting and grooming improvements. Under the hood, Houdini 22 ships a refreshed UI, continues its migration to a Vulkan viewport, and introduces controllable ML pipelines that plug in third-party models like SAM and Detectron while keeping results reproducible. Even Bullet gets love, with new bending and metal-fracturing behaviour.

Gaussian Splats change what a render farm is for
Here's the part most farms will miss. Traditionally, a render farm renders frames. Houdini 22 turns Gaussian Splat creation into a procedural, PDG-driven workload, and PDG-driven workloads are exactly what a farm is built to accelerate. Training a high-quality splat is compute-heavy and embarrassingly parallel, which means it can be distributed across many GPUs at once instead of tying up your workstation for hours.
Our farm already handles PDG/TOP graphs, so the same one-click workflow you use for frames extends naturally to Gaussian Splat training and rendering. Point your camera array, build your TOP network, and let the farm do the parallel training, then render and relight the result in Karma.
There's a second advantage that matters for anyone working with client material. Gaussian Splats are usually trained on real-world footage and photography, which is often confidential. Drop & Render runs in our own EU datacenter and is ISO 27001 certified and GDPR-compliant, so your source plates and trained splats are processed on EU-sovereign infrastructure, and they never have to leave Europe. For studios reconstructing sets, products or locations from proprietary footage, that's a genuine differentiator.
Ready within 24 hours of release, as an official SideFX partner
Drop & Render is one of the few official SideFX partners. We already tested the early beta releases of Houdini 22 to confirm that our farm will be ready when it releases, so you won't be waiting for us to catch up after launch.
On the farm you get:
- Every Houdini version, so you can match your local build exactly and avoid version-mismatch surprises
- One-click submission directly from the Houdini HDA across SOP, ROP and LOP networks
- Automatic asset scanning and remapping, so no more "missing texture" nightmares
- Direct-to-disk output: finished frames write straight to your drive, no manual downloads
- PDG/TOPs support built into the HDA, ready for procedural graphs and Gaussian Splat training
- Full simulation and file-cache rendering for bgeo, vdb and abc
Karma XPU and the VRAM question
A recurring worry in the Houdini 22 community is VRAM, because the move to Vulkan and heavier COP and Karma XPU workloads mean GPU memory pressure is only going up. That's a problem on an 8 GB or 12 GB workstation card; it isn't one on a farm.
Our nodes are built around high-VRAM, current-generation NVIDIA GPUs specifically so that Karma XPU, dense Copernicus graphs and Gaussian Splat training have the headroom they need. Instead of trimming your scene to fit a local card, you send it to hardware sized for the job, and your machine stays free for lookdev.
How rendering Houdini 22 on Drop & Render works
- Install the Drop & Render HDA in your Houdini 22 session.
- Choose your render engine: Karma CPU/XPU, Redshift, Arnold, Octane, V-Ray or Mantra.
- Submit with one click. Assets are scanned and remapped automatically; PDG/TOP graphs and caches are handled for you.
- Frames write straight back to your drive as they finish, ready for review the moment they're done.
That's it. The same workflow scales from a single test frame to a full sequence, and now to Gaussian Splat jobs too.
Key takeaways
- Houdini 22 is imminent; public release is expected around mid-July 2026, and it's a major, feature-rich update marking SideFX's 30th anniversary.
- Drop & Render will be ready within 24 hours of release, as an official SideFX partner that tested the early beta.
- The new Gaussian Splatting tools are a parallel, PDG-driven workload, ideal to offload to a farm for both training and rendering.
- EU-sovereign, ISO 27001 infrastructure keeps confidential footage and trained splats inside Europe.
- Karma XPU and heavy Copernicus graphs run on high-VRAM nodes, so VRAM limits stop being your bottleneck.
