I'm trying to find and edit a few parts for a model i'm doing currently, but with these parts, either part of them when I edit, since there's only one color option for me to change it, it doesn't work right and makes the part look weird, or the parts I'm looking for I can't find at all, which has me believe that they haven't been added, if this is true or not, can anyone tell me, since I've been having this problem for a while, and can't seem to find an answer.
