V-Ray 5 for Maya available now

Key features include:

LIGHT PATH EXPRESSIONS
Output any lighting contributions with Light Path Expressions for fine-grained control in compositing. Use boolean operations to easily combine LPEs, or quick start with built-in presets.

ALL-NEW V-RAY PROXY
Improve viewport and render speed with the new VRay Proxy node — а simplified single geometry node structure with easy-to-use, rule-based material and visibility assignments.

LIGHT MIX
Explore different lighting options from a single render. Interactively adjust lights, without rerendering with the Light Mix render element.

NEW COMPOSITOR
The new Layer compositor lets you fine-tune your images directly in the V-Ray Frame Buffer — without the need for a separate post-processing app.

ACESCG COLOR SPACE
Select industry-standard ACEScg for rendering with automatic color space adjustment for textures, dispersion, sun & sky, and light temperature colors.

ENHANCED GPU RENDERING
Power up your renders with all-new GPU features, including 2D displacement, support for OSL textures, memory tracking and initial out-of-core implementation to handle your largest scenes.
