I got a new computer, backed everything up from old one. Installed HDP 2021 onto this computer, transferred my license number. Imported files. Everything was going great until I did a 3D rendering of my build. The roof, pool, some of the block walls, some tables, posts, etc. are just a solid black color now. I tried to change the roof to red shingles just to see if it would refresh, but it didn't. I checked some older versions I had saved, same thing with those. Any ideas? It's a better computer now than old one, so doubt it is hardware that can't render. Maybe a setting or update I need to do or something? Attaching a screenshot.
