Hi Zuzana and Goetz,
yes, there are effects but they are not visual, and cannot be captured by a screenshot. What happens is the following, I save the textured object and open it in a 3rd party 3D modeler to fine touch the texture. Specifically I use 3D Coat.
When I import the RC generated model into 3D Coat to paint on the texture, the 3D Coat brushes do not work. They paint only certain spots and not others. Apparently they make use of the normals to decide on what side of the faces to paint.
As a matter of facts, if I process the RC generated mesh with meshlab, as I described, then 3D Coat paint brushes do work fine as usual. My conclusion is that the original normals are inverted or anyhow misdefined.
thank you
Massimo
