FAQ - Errors
Q: When using V-Ray for Blender with V-Ray for Maya demo nothing is rendered out when I hit render. A: Check the resolution - the demo version has limitation to maximum resolution of 600x450. Q: After applying a VRayMtl to an object it is rendered black. A: If you have "black" objects on render and errors like: warning: Failed to create object of type "BRDFVRayMtl" or warning: Failed to create object of type "BRDFCarPaint" or warning: [MtlSingleBRDF] No BSDF parameter specified this means that you are using an old V-Ray version. Update your V-Ray or use a Layered material. Q: I have downloaded examples from the site, but when I run render I only see the lights and I get no errors but 13 warnings A: If You see just lights and the render is completely dark/without any geometry hit "Export Meshes" before You hit "Render". Q: I can't find the scripts folder on OS X A: It is hidden inside blender.app, just right click and choose "Show content", then navigate to MacOS/X.XX/scripts/startup/vb25 Q: V-Ray renders broken .png images A: Leave the image compression to the default value of 90% Q: There is no V-Ray window on Mac OS X A: There is an issue with the 64 bit version of V-Ray Standalone on Max OS X - it doesn't have GUI; use the 32 bit version to have V-Ray Framebuffer window. You could also observe the rendering process by staring Blender from Terminal. Also enable Output panel and enable "Image to Blender" - this will load rendered image back to Blender in render end. Q: The image is not rendered properly when using Irradiance Map and Distributed Rendering A: Make sure you have saved the Irradiance Map file(s) (.vrmap) in a shared folder. You can use the network path when configuring where to save/load the file(s). Other computers on the network need access to them in order to render the images properly. |
