I have created models of a part that I created in Corel CAD. I have been trying to add texture to the parts but I can't get it to look the way I want it too. The parts are made of wood. Since the part is made of different pieces of wood. I am trying to get the wood grain pattern on the part to go in the right direction. when I unwrap the UVs only a couple of areas look the way I want them too. I have been trying to create faces on my models to separate the areas where the wood grain is going in a different direction but I haven't been successful. I am importing my models as STL files and trying to edit the mesh but nothing seems to work. Can anyone help me?
