... Maintain UVs and Textures?
- thomas (Unlicensed)
The exporter plugin reads and exports an object's existing UVW tags and does not perform any changes. Assigned textures are also evaluated, but here only a material's “Color” channel is analysed, and the path to an assigned bitmap is used. Other channels with bitmaps, e.g. “Bump” or “Displacement” are not considered. The reason is that RealFlow can only display the “Color” channel's texture. RealFlow provides a few more texture types, e.g. property and wet-dry maps, but they are not related to any Cinema 4D materials.
Put briefly: You are responsible for the correctness of an object's UV coordinates.
When you use wet-dry or property maps (e.g. for an object's friction) RealFlow will consider the included UV coordinates to map the textures onto the object. If these coordinates are wrong you will also get an unusable result. An unmistakable indicator for problems with your UVs is when wet-dry maps do not show any particle marks, but all surfaces are pale grey instead. Also when the wet marks are mirrored then you should check the UVs in Cinema 4D.
Objects with a texture tag, and an image map in the material's “Color” channel, can also be displayed with this texture in RealFlow. For a detailed workflow description, please read the “Using Textures” chapter from the RealFlow 2014 manual.
