I've been trying to change freckles so that you can wear them as an accessory so i can use contacts and blush on my sims at the same time. So far I've just been changing the category in CTU (and then pressing commit!) but when I try testing it in game it just turns my sims eyes orange. What am I doing wrong?

Since freckles use the face mesh as a base and accessories use the body (theoretically), I don't think you can just change the category like that. Why not just make the freckles into working topical details (the kind that you tick in CAS) instead?

It's not that hard, it just requires a bit of hex-editing.

I have a video tutorial on that here: http://thesimsupply.com/showthread.php?tid=228

The only downside is, you might need Rez Delnava's hack to get them to show up which hasn't been updated. However, just having one extra freckle probably won't cause too much of a problem.

Huh, Rez's mod still works for me I think...
