[solved] Does iOS support 32bit index buffers?

[simedj]

I can't find a clear answer to this question... what do OpenGL ES 1/2 stipulate? My code is built for D3D and GLES2 render systems so do I need to make sure each submesh is limited to 65535/3 indexed tris or was that GLES 1 only?

Any definitive online resources welcome.

OpenGL ES itself only supports 16 bit index buffers. But iOS supports the GL_OES_element_index_uint extension that allows for 32 bit buffers. And we do support it in Ogre.

Does that mean that if iOS is the only GLES platform I want to support, I don't need to do anything to make 32bit indexed models work? Or is there a config/build setting I'd need to enable?

That's correct. The index size is pulled from the mesh and the correct options are used in the render system according to that info.
