I've moved your reply which was posted into another thread here:
quote:thank u for answering, yes i assigned a multi subobjects material to different faces using uv map then using unwarp uv i flattened the mapping, anyhow maybe i made a wrong manipulation cause on other objects the plugin work fine, it is realy a nice plugin.
Well if you have valid texture coordinates on the object then there are the possible cases that I can think of which may cause black render:
you are trying to texport using mapping channel A but the mapping coordinates are applied on another mapping channel
mapping coordinate face normals are flipped thus the backface cull option of texpoter causes them to be culled. You can try turning off the backface cull option. This happens after non-uniform negative scaling such as symmetry modifier.
Texporter is set to show only the visible edges but all the edges of your mesh are invisible
besides that I can't think of any other generic cases. If you can send the object you are having problems with, I may be able to help more.
