Shared vertex buffer

Hi all!
I'm trying to use oFusion for exporting Max model to a mesh format and I've came upon a following problem. After I load models at Ogre engine, I do some additional processing, and this processing relies on vertex buffer to be shared for this particular mesh. However the meshes I get from oFusion all come with dedicated buffer for each submesh, and I can't find a way to change this behaviour. Can somebody give a hint where should I look and if it possible at all with oFusion?

Thanks!

Shared buffers is not supported (there is not many real cases where this can be used and that justifies the implementation)

Is there any reason why you can't modify the shader to use the vertex buffer stream as supplied?

Hi Lioric,
Thanks for the quick answer. I do not do this for shader, but rather for some CPU-based mesh processing. I guess if the only option I have is to change my code - I'll do it
