You pretty well listed all my dirty secrets from my bad SkUp habits that I’ve gotten away with up until now. This is how I’ve always done things but it looks like it caught up with me today or I added the straw that broke the camels back. And yes I probably piggy backed the Layout file from a previous file that might have been linked to another SkUp file still. Thank you for looking at all of this and pointing out what I’m doing wrong. Lot’s of old revisions. In any case I have to look in to how to reduce my material size somehow for future use. What Clean Up file do you use to reduce edges, faces, etc…I’m not sure how I feel about merging material. My materials are usually very specific. I’ll have a look and let you know if it works better on my end. Thank you!
