Ok, hello again all.

I am going to request that unbroken have another look at his obj files , and try to fix the materials as discussed and perhaps group some of the parts.

for a simple prop the main frame, front wheels, axles, castors and castor wheels could all be one part with different materials.  The castors for example are two castors in one obj file and so cannot be rigged without splitting into two obj files.  (or parts)

The reason I am making this request is the front wheels. When I look closely in Poser they have some normals facing in and some out. Poser makes this look broken.  I can't find a fix that doesnt involve changing them in modeller.  I have not checked other parts.

Let me know if thats acceptable. If not I will continue with what I have.
