Our team is pleased to present and recommend for use the plugin "V-TayMtl Converter 3", which, in addition to converting materials, lights, cameras, proxies and other scene components, can now also automatically adjust the workspace in ACEScg or sRGB for rendering in V-Ray!
This corresponding function does the following:
depending on the option selected, switches to ACEScg or sRGB in the [Render Setup> Settings> Color management> Rendering RGB primaries]
finds all VRayBitmap and VRayColor maps in the current scene and determines the purpose of these maps - displayed in color (diffuse (albedo), reflect, refract, translucent, sss, selfillum, environment/light etc.) or with technical data (bump, glossiness, displacement, ior, anisotropy etc.) and separates the map instances (if any) in the conflicting slots.
toggles the [RGB colorspace] and [Color space transfer function] maps according to the selected color space. In this case, the function determines whether a bitmap texture with special suffixes in the file name (_lin_srgb, _srgb, _acescg, _raw) is used or the file name is used without a suffix.
optionally, you can enable gamma correction in [Render Setup> V-Ray> Color mapping] and rename duplicate map names that may be after splitting instances in conflicting slots.
"V-RayMtl Converter 3" allows you to switch to the desired Color Space with one click!
