First off this post is in the wrong section. This should be in Help & Support. I’m not trying to tell you what you should and shouldn’t do but if you don’t know how to look at the already added player models and understand it or at least google it first before going strait to this forum and posting then please at least google it. It’s a pain in the ass when people come up here and post their problems in the wrong section.
