I’m designing the trees for my PC game and taking the opportunity to learn Blender 2.6 at the same time. I want my trees to be limited to single objects using a single texture. I want the tree bark texture to transition from a rough looking bark at the trunk of the tree to a smoother bark at the top of the tree. I have a texture containing a rough bark image and a smooth bark image. I have created 2 UV maps for the tree, one for the rough bark and one for the smooth bark. I can switch between my UV maps in the UV Editor. How do I blend the textres/UV Maps, and how can I then interpolate between the two so that I have more rough bark at the bottom of the tree and more smooth bark at the top of the tree? OR am I going about this entirely wrong?
