I'm still around. Modding has been non-existent for the last few months as RL has taken precedence. The last week I've managed to do a little bit more which you will see shortly, but as far as updating what needs to.. I haven't. It was easier to 're-learn' from starting a new project.
@zak4862 , sorry but I've never used sketchup, so am unsure how it would import the model into blender. All i can suggest is to understand the basics of blender and re-read my tutorial, when i'm talking about UV unwrapping that is when i'm preparing the model for texturing.
When using blender and if you already have a texture file image, open it in the UV/Image editor, then enter the mesh of your model into edit mode and start selecting the faces and UV unwrapping upon the loaded texture in the the UV/Image editor.
I think a couple of the other banished modders use sketchup and import into blender, they might know more about importing the textures with it.
