1. replace the current .blend file with the attached
2. Compile the iPhone Solution
3. start the app in simulator or iPhone

What is the expected output? What do you see instead?
- The model of the woman is missing.

What version of the product are you using? On what operating system?
The Head Version

I did not know this was a limitation.  

The only way to properly fix this is to, add test that the total number of 
blender mesh indexes is less than 65536, then skip conversion. Any more and the 
mesh won't fit into a 16bit hardware buffer.

OgreKit uses both (with 65536 as the pivot)

Ok.
Where should I test the total number of Mesh indexes and which Conversion 
should be skipped.

Thanks
Andy

Currently, you would test in blender as the total number of faces. (the Fa:#, 
information at the top of the blender window )

In the source code, gkMesh should test and skip conversion to Ogre if 
(mesh->getIndexBuffer().size() > 65536)

You can avoid this limitation by divide your big mesh to submesh.

1. select your mesh, enter edit mode in the Blender.
2. select many vertices & seperate(P)
3. repeat  step 2 until the seperated mesh don't use 32bit indices. 
4. join all seperated mesh to one mesh.(Ctrl-J)
5. done.

We could also split up the mesh at run-time, before feeding it into the 
graphics engine. That's what happened in IrrKit (the Irrlicht based version)

Can you see textures on other models or All textures is invisible in the scene?
