V-Ray Next for Maya Update 2 is now available.
The update adds support for hardware-accelerated ray tracing on Nvidia’s RTX graphics cards. There's also a new hashmap-based light cache, procedural dust and scratches as a lens effect, Bercon noise, deep EXR output, and support for the V-Ray distance texture when rendering with V-Ray GPU.
V-Ray Next can now use the power of dedicated RT ray-tracing cores in Nvidia’s GeForce RTX, Titan RTX and Quadro RTX GPUs to speed up the rendering process. This is an alternative to the existing CUDA engine (select manually when rendering on an RTX card).
Another big thing is support for the V-Ray distance texture, VRayDistanceTex. What is more, users get a “more GPU-friendly” implementation of the light cache that reduces flicker when rendering animation.
