Every time we switch back and forth between two scenes, the node materials are re-rendered. This can take a long time depending on the scene. I noticed that it only happens when VRay is set as the render engine. Normal node materials with default engine does not re-render here. Is there a way to freeze the preview of a material or to fix the problem in general? The standard VRay materials do not re-render.
