V-Ray 7.4 Expands GPU and Gaussian Splat Power in Maya and Houdini

V-Ray 7.4’s Real Message: GPU Choice and Modern Pipelines Matter

V-Ray 7.4 GPU rendering for Maya and Houdini is a pair of coordinated updates that emphasize broader GPU choice, more intelligent handling of 3D Gaussian splats, and tighter links to modern pipeline tools like Bifrost and Solaris, all aimed at keeping high-end VFX and animation workflows responsive and future-proof. Chaos did not ship a flashy new flagship feature; instead, it doubled down on the idea that artists need flexible, hardware-agnostic rendering and direct support for emerging formats baked into the tools they already use. This is an opinionated move: rather than chasing buzzwords, V-Ray 7.4 focuses on the boring but decisive details—performance, integration, and practical controls—that determine whether a renderer fits into production or becomes a bottleneck.

On the Maya side, the headline is clear: AMD GPU rendering joins existing options in V-Ray GPU, the hybrid GPU/CPU render engine, for the first time since V-Ray 3. That alone changes the buying calculus for studios that have standardized on AMD hardware or want the freedom to mix GPU vendors without sacrificing V-Ray 7.4 GPU rendering performance. The Houdini edition, meanwhile, pushes deeper into Houdini Gaussian splats and volume work, adding relighting controls and more nuanced volumetric options. Taken together, these updates say that Chaos sees the renderer not as a monolithic product, but as a family of pipeline-native tools that must respect the realities of different DCCs, hardware stacks, and data formats.

Maya: AMD GPU Support and Bifrost Integration Are More Than Box-Tick Features

In Maya, the most consequential change is not some exotic shader; it is the decision to welcome AMD GPUs back into the rendering fold. V-Ray 7.4 for Maya boosts performance by "up to 13%" on Windows and up to 6% on Linux, with additional speed gains available to AMD GPU users thanks to renewed support inside V-Ray GPU. That support, implemented via the open-source HIP framework and previously rolled out in the 3ds Max and Blender editions of V-Ray, signals that Chaos accepts heterogenous GPU farms as a fact of life rather than a corner case. This matters because studios are tired of lock-in: Maya AMD GPU support is not a courtesy, it is an acknowledgment that renderer choice should not dictate hardware politics.

The Bifrost story carries the same theme of practical respect for existing workflows. V-Ray 7.4 now supports Bifrost 3, the latest iteration of Maya’s node-based simulation framework, and adds coverage for meshes, strands, instances, animations, and material assignment directly through the Bifrost graph. Instead of forcing TDs to jump through translation hoops, the renderer meets Bifrost where it lives. Add in extended support for 3D Gaussian Splats, including relighting controls and GPU-based clipping of unwanted regions, and it becomes clear that Chaos is aligning V-Ray with the formats and tools that are already gaining traction in VFX. These are not headline-grabbing gimmicks; they are targeted answers to daily production friction.

Houdini: Gaussian Splats, Volumes, and Solaris Show a Clear Direction

On the Houdini side, V-Ray 7.4 takes the same philosophy and applies it to where Houdini excels: complex data, volumes, and layout. Support for 3D Gaussian Splats, first introduced in V-Ray 7 for Houdini, is extended with controls for relighting splats directly inside V-Ray. That is a strong signal that Chaos expects splat-based representations to be more than a research curiosity. By letting artists shape lighting on Houdini Gaussian splats within the renderer, V-Ray 7.4 stops treating splats as opaque data blobs and starts treating them as first-class citizens in the lookdev process. The decision to add native parallax interiors via VRayParallaxTex, removing dependence on third-party OSL shaders, follows the same logic of pulling common tricks into the main toolset.

Volume work is where the Houdini update quietly becomes strategic. New control options for rendering volumes include a Multiple Importance Sampling option for volumetrics, building on the "re-imagined" Volume shader introduced in an earlier V-Ray 7.2 update. This is not decorative: nuanced sampling is the kind of thing that determines whether volumetric scenes can be rendered consistently or devolve into noisy compromises. On top of that, support for Open Image Denoise as a hardware-agnostic denoising option joins NVIDIA OptiX and Chaos’s own denoiser, which again points to an intent to avoid vendor lock-in. It shows an attitude: V-Ray wants to be the renderer that respects the chaotic mix of hardware and data that defines Houdini-based work.

Solaris, USD, and Pricing: V-Ray Is Betting on Standardized, Rental-Only Pipelines

The deeper integration with Solaris in Houdini and USD-related improvements on both sides say more about Chaos’s long-term view than any single shader. V-Ray 7.4 improves support for Solaris, Houdini’s look dev and shot layout environment, adding compatibility with the Stereoscopic Camera, night sky controls for the V-Ray Atmosphere LOP, and better motion blur handling. That is a clear vote of confidence in USD-driven, layout-centric workflows. On the Maya side, support now covers USD for Maya 0.35 and 0.36, the plugin versions tied to the latest Maya releases. Again, this is not glamorous work, but it is essential: a renderer that cannot live comfortably inside USD is a renderer that gradually gets sidelined.

The business model follows the same pragmatic thread. Both V-Ray 7.4 for Maya and Houdini are available rental-only, with V-Ray Solo subscriptions priced at USD 89.15 (approx. RM420) per month or USD 540 (approx. RM2550) per year, and V-Ray Premium at USD 129.90 (approx. RM615) per month or USD 778.80 (approx. RM3680) per year. Prices have increased by USD 10 (approx. RM45) per month and USD 60 (approx. RM285) per year compared to the previous release. The opinionated takeaway here is that Chaos believes V-Ray’s value lies in staying current with standards like USD, Bifrost, and Solaris—and it is comfortable charging for that ongoing alignment rather than selling a static, perpetual product.

Conclusion: V-Ray 7.4 Chooses Pipeline Reality Over Hype

V-Ray 7.4 for Maya and Houdini is not about one killer feature; it is a clear commitment to the unglamorous realities of production pipelines. Maya AMD GPU support reopens hardware choices and boosts performance within V-Ray 7.4 GPU rendering workflows. Houdini Gaussian splats gain relighting controls and volumes gain more intelligent sampling options. Both editions deepen their ties to Bifrost and Solaris, reinforcing that modern VFX work revolves around simulation graphs, USD layouts, and mixed-format assets. The opinion here is straightforward: Chaos is betting that artists care less about buzzwords and more about whether the renderer respects their tools, hardware, and data. With V-Ray 7.4, that bet looks well placed.
