If the issue is not found in the render settings or materials, it could be caused by the geometry. The troubleshooting process could dive deeper by going through the parameters of the problematic Material but in most cases, this is not needed. Once the problematic Material/Map is found it could be replaced with similar material or it could be recreated from scratch. If it’s still there, continue replacing materials until it disappears, When the issue disappears, undo the last replacement and focus on those materials.
A good strategy is to replace half of the materials and check for the issue. (Maya) Run the Convert Scene for V-Ray tool. Make sure all material checkboxes are enabled. Replace Materials/Maps of imported objects/libraries - imported assets from 3rd party libraries/software are sometimes questionable. Replace non-V-Ray Materials/Map - the issue may be caused by an unsupported Material/Map of another render engine.
If the issue persists, continue the investigation elsewhere. This is a quick and effective step to save troubleshooting time. It is recommended to start the debugging process by restoring to the Default Render Settings. Oftentimes parameters are wrongly interpreted or exaggerated. Resetting the V-Ray settings to their defaults is a simple step to determine whether the issue lies in the setting values or status. The instant feedback is helpful when setting changes are done frequently and can quickly direct you to the culprit.Ĭheck Render Settings (Resetting V-Ray Render Settings) IPR (available in 3ds Max, Maya, SketchUp, SketchUp(viewport) Rhino, Revit) is a handy tool for scene debugging. In such cases follow the bullet points individually and track which one resolves the Note: the changes mentioned above might prevent the issue from reproducing. Use Bucket Sampler with Min/Max subdivs of 1 ĭisable global features like GI, Displacement, Subdivision and etc. Use small image resolution or a region render Tweak Render Settings for faster rendering:
