This does not make sense.  Looking at the code, the only time 
IRRenderer_Texture_ConvertSize is called is if the texture dimensions 
are not powers of 2, or they exceed the GL_MAX_TEXTURE_SIZE parameter 
of the OpenGL renderer.  Neither should happen for a 256x128 texture.

Does anything show up in the console?

No idea.  I duplicate trimeshes all the time.  Though I don't use 
ordered display groups.  If you have a 3DMF file that, when loaded, 
cannot be duplicated, you can send it to me and I'll take a look.

1024x768 is pretty big, and of course 768 is not a power of 2, but 
still this should work.  Conceivably it could depend on your video 
hardware.
