Painting the exterior in Photoshop
The first thing I do when I get my base renders is make a list of all the changes I want to make. For the rover I look at how to get back to the faceted look that I was originally going for. This means simplifying surfaces wherever possible, in particular the area around the escape hatch. I don’t change too much however, because I need to stick to the metric block-out I started out with. In addition, I check in with the 3D department, to ensure that the new shapes I’m coming up with are physically possible.
