Column width 50% UI Text Box type warning For your Dome light to work properly with Dome Tex make sure the following are set appropriately in the Details panel of the .hdr texture: In Compression category, Compression Settings are set to HDR (RGB, no sRGB). In File Path category, the Source File is valid and accessible. V-Ray loads the texture from that directory during rendering. If the texture is not found at the specified location the dome light will not contribute to the lighting and the scene will render black. In Texture category, sRGB is not checked. This setting specifies whether or not the texture has linear colors or sRGB color values. In the case with .hdr textures they have high dynamic range values in linear color space and sRGB should be turned off.   Column width 5% Column width 45% Image Removed Image Added
