There is one more place to control color mapping - BitmapBuffer - for texture file assets. It has two parameters for converting the image file colors - gamma and color_space. The gamma parameter is considered only when color_space=1 and makes texture reads apply inverse gamma to decode gamma-compressed values to linear. Most integer formats will require setting color_space=1 and gamma=0.454545. When color_space=2, sRGB decoding is performed (similar, but not identical to color_space=1 & gamma=0.4545). Since V-Ray implicitly converts JPEG (or PNG and other 8-bit formats) file data to linear RGB while reading the file, it isn't necessary to change gamma or color_space from their default values for such textures. This is only necessary for images baked with gamma encoding (before any internal conversion, such as JPEG's YCbCr).
