V-Ray Next for Maya is now in open beta and everyone can try it out!

We also have a new section in the forum that is open for everyone that wants to give their feedback:
https://forums.chaosgroup.com/forum/…-beta-for-maya

Here are the highlights of this release:

- New IPR architecture - the IPR architecture has been redesigned allowing instant feedback and supports for animations.

- New Toon shading - the new V-Ray Toon material (VRayToonMtl) allows for complex non-photorealistic cel shading. The V-Ray Toon shader for outlines (VRayToon) has also been updated with new features.

- Adaptive Dome Light - the new Adaptive Dome Light delivers faster, cleaner and more accurate image-based lighting. It also eliminates the need for separate light portals.

- Auto Exposure & Auto White Balance - the V-Ray Physical Camera is enhanced with options for Auto Exposure & Auto White Balance.

- Integrated NVIDIA AI Denoiser - NVIDIA AI Denoiser is available as an alternative denoising engine. Note: For Beta 1, this feature is available on Windows only.

- Faster GPU Rendering Architecture - V-Ray GPU has been redesigned for better performance and faster parallel processing.

- GPU Volumetric Rendering – V-Ray GPU supports volumetric effects such as fog, smoke and fire.

- New Hair Shader - the new hair material (VRayHairNextMtl) renders more realistic hair with intuitive melanin color controls and with accurate highlights.

- Denoise Render Elements - denoised Render Elements can now be seamlessly recomposed back into a denoised beauty pass.

- VRayMtl - a new “Metalness” parameter is available for easy support of PBR workflows.

- V-Ray SDK - updated rendering architecture that takes full advantage of modern hardware, including optimized vector calculations using SSE 4.2 and customized Intel® Embree ray tracing library 2.13.

- Layered Alembic Workflows – now supporting Alembic 1.7 with layering to enable faster, more efficient handling and updating of Alembic data.
