Maps – Enables (default) or disables texture maps. This option is useful for troubleshooting renderings, for example for determining the extent to which texture maps are contributing to noise or other rendering artifacts.
Filter Maps – Enables (default) or disables texture map filtering. When enabled, the depth is controlled locally by the settings of the texture maps. When disabled, no filtering is performed.
Max Mipmap Resolution – Sets the maximum resolution for mipmaped files. All planes with higher resolution from the file won't be used. If set to zero0, the original file resolution is used.
Bake Cinema 4D Shaders – V-Ray does not support natively Cinema 4D textures. For the purpose of rendering, V-Ray internally bakes them. This option allows control over the textures' resolution globally.
Width/Height – Specifies the Cinema 4D texture resolution globally. If you need fine-tune quality control, use the VRayC4DBake utility texture.
