The only problem I think that only two things could cause the animator to be broken is you turned off the loop time or you don't have wire defaults on. For me it worked perfectly first try.
I have the files for it, I've try porting it by no luck since it's using animation rigs, and bolden. but if anyone is able to do so. Let me know! My discord is dwxght_soft
