Quote - Well there are numerous places that either seem to twist from one set of normals to another, or actually have entire polygons with reversed normals.

This causes havoc with how the shader interprets interactions with light. By me putting a proper wood shader here, it becomes clear that the geometry is totally messed up.

I marked up some of the issues I saw on just one section (fireplace).

The wood panels on the right here are behaving correctly. Those on the left are not.

And the fireplace has issues, too.

Thanks for replying!

That's really interesting. I've had some serious issues with messed up geometry when trying to use Reality 3. I sent two of the sets to Paulo at Pret-a-3D and he said that the normals were all wrong. About 33% of the content that I've tried in Reality 3 has issues such as that, which is another reason that I gave up on using it.

I've had no such issues in Poser, as of yet.
