What is V-Ray light cache?
Light caching (called “light mapping” in older versions of V-Ray) is a technique for approximating the global illumination in a scene. The light cache is built by tracing many, many eye paths from the camera. Each of the bounces in the path stores the illumination from the rest of the path into a 3d structure.
How do you save V-Ray light cache?
To save a separate Light Cache file for each frame of an animation, append d suffix to the name of the file.
Why is my V-Ray so slow?
The more polycount, the slower the rendering. If you are using Vray, always proxy the ones with high polycount. I.e. If you render your final image at 3500px you don’t need more than 4000px image anywhere. Material wise: avoid using too much glossiness and highlights.
What is Max Subdivs in V-Ray?
Max subdivs – Determines the maximum number of samples for a pixel. The actual maximum number of sampler is the square of this number (e.g. 4 subdivs produces a maximum of 16 samples).
What is irradiance map in V-Ray?
In V-Ray, the term Irradiance map refers to a method of efficiently computing the diffuse surface Irradiance for objects in the scene. The Irradiance map is in fact a collection of points in 3D space (a point cloud) along with the computed indirect illumination at those points.
How do I get high quality render in V-Ray Sketchup?
In V-Ray for Sketchup, Rhino and Revit, render quality can be improved by dragging the Quality slider to a higher quality preset. Increasing the sampling limit for higher image quality requires more time to render and in this case slower render times are expected.
How long does V-Ray take to render?
Most renders will give their first image within 30 seconds, but it may take 3/4 hours to give a clear image. Large images (greater than 5 megapixels) may need to be left overnight to become clear.
What is min shading rate in V-Ray?
Min shading rate – Controls the number of rays shot for Anti-aliasing (AA) versus rays for other effects like glossy reflections, GI, area shadows, etc. This setting is especially useful with the Progressive image sampler.
How reduce V-Ray render in Maya?
To denoise a separate Render Element, select it from Render Settings > Render Elements > Added Render Elements. In the Attribute Editor, go to Extra Vray Attributes and enable the Denoise option.
