In the picture you see the same prop.
On the left side (imported and textured obj.) before and on the right side after turning into a prop and reloading from library.
I modelled it in Cinema and exported to obj. I noticed this kind of disappearing with two other of my models. One common thing is that in the areas that don`t show up boolean operations were involved in creating the model. In Cinema everything is fine and normals seem ok. But in Poser !

Any clues to what went wrong during prop conversion -
Is it a Poser Problem?
Do I have to curse Cinema?
Or just simple human incompetence?

Heh, I know it has something to do with reversing normals, but what the exact fix is, I don't remember. Try playing with normals settings in poser until someone with a more definitive answer comes along. Tilandra (also a Kel(Lee) C...)

Had such happen before, but the missing poly showed on the imported *obj, not after making a prop out of it.It happend to me after doing boolean operation on the object,so i try not to use them.

I am not familiar with Cinema4D but check if you have non-planar polygons, if so triple them, check if you have polygons with the normals reversed if so flip them. You might have back to back polygons that need to be merged. Try to have only three point or four point polygons. Hard to tell without seeing the wireframe.

Do the missing Poly's show up on render? The fix I use for small problem areas is to zoom in on the areas, use the grouping tool, select & flip the individual polys.

Im not a expert with the Poser Grouper, but I read bloodsongs tut about fixing normals and I basically did like leather-guy suggested - no fix - In any case it took me longer to play with the grouper than to reconstruct the problem areas with a different approach (no use of booleans)like thgeisel suggested. I try to avoid it now - just would have been nice to use it some times... At one time I got so frustrated that I downloaded the trial version of Rhino and started digging through the interface. Maybe its the kick in the ass I needed to learn Rhino whick is I think a better choice for modelling for Poser Thank you all for your response! kelc
