Gerald Hoffpauir asked about the background of my View-Master image and how I’d made it. I had to admit that it was just a boring old HDRI because I didn’t know how to make realistic looking weathered cardboard boxes…
So I set myself a goal of learning how to do it this afternoon.
Edge extrusion (as opposed to the face extrusion I’d only ever used before)
Solidify and UV Unwrap BEFORE you bevel the edges
Thanks Gerald for asking the question that pushed me to learn something new. Still a long way to go, but this is a start.
