[branched] missing detail in rendor
I am having a similar problem. In my case, my render of a model that came from a STEP file lacks all detail in the render (i.e., the detail that is clearly visible when working in the Design view).
DESIGN VIEW:

RENDERED VIEW:

I've tried cranking up the lighting all the way, moving the lighting around, etc., but it always comes out as solid black.
FYI -- all my other projects originated from a SLDPRT 3D model or an IGES 3D model, and those always come out great as photo-realistic images with lots of clarity and detail. However, this one converted from a STEP 3D model has been very difficult.
Thanks for any help you can provide on this.
