I know exactly what you mean. Although as of yet i have not done any texture mapping. I was just making a 100% bryce spaceship and the model was pretty descent but i just couldn't seem to get the textures to work right. I dont know what it was. Eventually... after many hours of playing with textures I finally got something that was semi descent. I'm about to post the model in the free stuff section and put in a new post telling people about it in just a few minutes.
