Importing from Inventor and Rendering

[CMP_Design]

When I Import my models from Inventor as a body object or mesh, the topology is very little and there are ngons. Do i still have to convert to an editable ploy and clean up ngons in order to apply a textures for a detailed render? The models are clean when imported and look nice.

ps.

I guess what I am asking is what is the correct workflow?

I work a lot with imported from inventor or other software models (sat,step) and inside 3dsmax as Body Object . in my experience no need to convert them to epoly unless to u need to modify them .

what about adding a texture to the models that would require UVWunwrapping? Is it still ok to keep as Body Object?

In that case you should probably convert to Mesh/Poly first since any change to the Body Object (like changing tessellation, joining surfaces etc) will change the vertex number/order and any information stored in the Unwrap modifier will be lost. Keep in mind this applies to Unwrap only, not the UVWModifier - that one will continue to work since it 'projects' mapping on the fly.

One tip - if you convert Body Objects to Mesh/Poly, a lot of vertices will not be welded which makes it impossible to unwrap properly. In that case, use the ProOptimizer modifier, enable 'Merge Vertices' with a tiny threshold, press Calculte and convert to Mesh/Poly. Now all vertices will be welded and Unwrap will work just like with any other mesh.

Ok. Thanks for the advice. Looks like i'm heading in the right direction.
