I've used the same renders of my Beetle model on my demo reel for at least two semesters now, so I've finally forced myself to go back and start fixing up some things. I put new shaders on it and built new windows. Later I'll start texturing almost from scratch as I have some more geometry I have to change which means new UVs. I should probably put a license plate on it again too, I'm not sure when that went missing.
