: This is arguably the most impactful technical update. It allows users with NVIDIA RTX cards to utilize the dedicated ray-tracing cores for much faster interactive and production rendering. Color Assistant
For animations or multiple views of the same scene, save your light cache and irradiance map to disk and reuse them. This can reduce rendering time for subsequent frames by 50% or more.
Noise (grain) is your enemy. The key is the Noise threshold in the Render Settings > Sampler . Vray 4.2 Sketchup 2020
This is often caused by out-of-memory errors. Check if your textures are unnecessarily large (e.g., dozens of uncompressed 8K textures). Use the SketchUp Purge Unused function to clean the file, or convert high-poly geometry into V-Ray Proxies .
For users working with scanned materials, V-Ray 4.2 added triplanar projection mode to VRScan materials. This means scanned textures can be applied to models without needing UV unwrapping—particularly useful for complex organic shapes or when working with client-provided models that lack proper UV mapping. : This is arguably the most impactful technical update
The official SketchUp community at Chaos Group is an excellent resource for questions, troubleshooting, and feature discussions
Gone are the days of manually placing Sun objects. This can reduce rendering time for subsequent frames
Switch your primary GI engine from Irradiance Map to Brute Force . Brute Force avoids splotchy artifacts entirely by calculating light values per pixel. 3. Materials Appearing Flat or Lacking Depth
: Performance optimizations made GPU rendering approximately twice as fast as previous versions.
Finding the perfect color for materials, lighting, or environment settings can be surprisingly time-consuming. V-Ray 4.2's Color Assistant simplifies this process by providing intelligent color variations based on hue, saturation, and luminance adjustments.
However, the acceleration isn't uniform across all scenes. Chaos Group's internal testing showed that scenes with massive geometry but relatively simple materials benefit the most—sometimes seeing improvements of over 170%. Scenes with complex material calculations but simpler geometry may see more modest gains, typically around 7-30%. For RTX 2060 users, test renders showed improvements from 4 minutes 34 seconds down to 3 minutes 5 seconds—a meaningful reduction when rendering multiple iterations.
