Multi-material is not supported by OpenGL, neither multi-textcoord (unless you redefine the texture coordinates on the fly), so these are not very useful cases to support. > [...] >> They need to be separated into >> different objects, based on material. > Only for (2) > A better alternative should be to export one drawable per material. >> Somebody mentioned here they made a >> script to do that? > Yep, it was me :p. This is not a very good solution, what if I have two materials assigned to the same rectangle/face? You will generate two overlapping faces at the same position and z-fighting occurs. That's bad. Blender allows this, however this is a bad case for OpenGL. >>> Or someway already available in Blender to separate the >>> selected part of a mesh as a new mesh??

Select the object in edit mode (TAB), unselect all vertices (hit A), then B twice (to get selection with the "circle"), select the vertices of the face you want to separate and hit P. It will make a copy of that face as you can see when you go out of edit mode and move the original object. Even easier method - go to UV mapping mode, select the faces you want by clicking them, switch to edit mode (TAB), they will be still selected. Then just hit P to separate them. Problem solved.
