I am bumbling my way through creating a file and I am doing something wrong, just not sure what it is. I am happy with my design and thought I would add a material over it, just for a bit of realism. It looks like a simple process and I have done it once on one part of the model but when I go to select another part to put the material on, it wont do it. I suspect I am only one mouse click away from getting right but I am not sure why it worked on one face but not another.
