Adding more details to the bump map

Now that I've got my corrugations on the main sides and end of my shipping…container, I'm ready to put other bump parts in.…I'm going to look first at the corner boxes here. I'll press Z to zoom and zoom in on them.…We've unfolded these boxes and we can see the UVs are overlapped here, as…there's only two of these pluses available.…What I'm going to do is use a circle in here to simulate the depth in the hole;…in reality, it's going to be just black in the diffuse texture.…First, I'll put a new layer in.…

My general rule in Photoshop is when in doubt use a new layer.…If you are thinking about putting something else in, use a new layer.…Keep this flexibility going all the way through.…What I've also done is to save this as a PSD.…What I like to do is to save this in a working directory.…I've put a directory called working in my images folder in the 3ds Max project.…That way when I'm browsing for textures, all these working PSDs are down a…directory and don't show up on the list;…only the finished textures are in images.…
