Da qualche tempo è disponibile uno strumento di Unwrap/re-Wrap da utilizzare direttamente in Rhino. Questo strumento,non è specifico di VrayforRhino, ma generico, permette di "stendere" la mesh di un oggetto, anche polisuperficie, in modo da avere a plan view of all sides. Once stretched faces can be changed, with standard navigation tools, scaling and rotation.
The software uses a texture "base" useful to collimate the size of the faces, replacing that with a texture created ad hoc with Photoshop can be mapped, praticamnete flawless, even the most complicated objects.
once the editing stage is the mapping possibilòe reapply the original object with a simple click.

In addition to the package are also a useful plug-in toolbar.
I did some testing with this instrument and I can assure you that it is very intuitive. The hard part is to readjust and reconstruct the faces to match their expectations. Speaking of a free tool, which is useless for 3D painting, we can accept this effort.
