How To Get a Render back to my initial UV Map

[Ramjet]

The simulator process engine gives this results :

All 3d objects made with wings and paint with Photoshop











The problem is that it is not enough good when I look to the renders in the the forum.

It is probably a problem with textures materials that I don't enough master in Photoshop. Here is my question with Kerkythea.

By the way is there free 3d painting or texturing soft, the Wings 3D palette seems to be light, or I missed some important things?

Thanks for your answer Micheus.
