Allright Rig For Unreal Engine 4

[anonymous_user_bb2c1c15]

Thank you for this detailed explanation, !
First of all, you don’t need to create a “CustomController” for the LeftUpLeg bone. It seems, that system conflicts with the existing controller when trying to add FK controllers to the limb. Also you need to set “HipsIk” as “Parent Bone” for your Fk/Ik leg rig. There is no shoulder bone in leg, that is why you don’t need to create additional controller like in case with shoulder.

Alright, I did what you suggested but the error is still happening and crashing Unreal. Here’s a clip of that.

Edit: I use HipsCtrl instead of HipsIk in the video. I tried with HipsIk and it still crashes. No change.
