Sorry to start a new thread, but I didn't want to put a ton of images on one page. Here's two more pictures of work I've done. They're the Techbot textures. I'm going to post two pictures of the Techbot, one with a clean texture and one dirty. Please give feedback.

dirty

Not dirty enough. Needs more rust. Maybe some dents and scratches, too. Fantastic job, otherwise. (Bob?)

How's this?

Better! And I wasn't criticizing the name; I was just curious. There's a robot named B.O.B. in Disney's The Black Hole.

I was working on making the bottom glass broken, but it doesn't want to work. The highlight stays there with the transmap, and if I turn off the highlight, it looks terrible. So it will stay that way. I changed the symbol for the name so I could give the robots more of a variation. I'm sort of leaning towards a more ancient alien look with the 'dirty' robots. I want to make the 'clean' robots look as if they were man-made.

Concerning the broken glass bottom:

There's a trick to manipulating the highlights on a transmapped object: use a texture map in addition to the transmap. Highlights won't show up against a solid black color.

Create a greyscale transmap with the broken part in solid black (so it'll be completely invisible). Use the same transmap as the dome's texture map. You can still make the glass red (or any other color) using the Object Color button on the Surface Materials panel.

Or you could tint the texture map red instead (so long as the broken part remains pure black).
