Basically, I have got this skinned mesh I have imported from Mixamo into Roblox Studio with a Walk animation imported as well, and when I use the R15 Animate script that comes when you load up the game and copy it from inside the character and I paste it into StarterCharacterScripts with my animation ID set for the walk animation, it doesnt play the animation whenever I walk. I have looked for solutions such as deleting the animation controller out of the model but I already have done that.
If anymore info is needed to solve this problem I would be glad to help and take more pictures!
