http://www.realsoft.info/modules.php?op=modload&name=News&file=article&sid=66 http://www.realsoft.info/modules.php?op=modload&name=News&file=article&sid=115 BTW: In my opinion "you" should think about the difference between "connected" and "separated" UV-faces, too. Very important for SDS in "smoothed mode". Maybe texturing objects is as hard as animating objects :-? Have in mind that RS has UVW-Coordinates (W is the UV-Coordinates Z-Axis, important for using UVs with procedural textures ;-) not UVs only... If that's not enough: You have the possibility to combine different "layered" UVWs ;-) One last link left: RS v4.5 ;-) http://the-final.com/rs/Mapping_is_everything.zip (Head has multi UV via channels) My conclusion after working since some days with RS Uvs. It's getting better and better. Not perfect at all because of the different smoothing but ok for me.
