Objects - Texture: MultiBody
MultiBodies do not support wet-dry maps and you can only apply a diffuse map.
Load Texture
You can load any texture map and apply it to an object with UVW coordinates:
If the UVWs are wrong in your 3D program then they cannot be correct in RealFlow.
RealFlow does not offer any tools for fixing UVWs – you have to do this inside your 3D program and reexport the object.
RealFlow is not able to handle bump, specular, displacement, or normal maps.
