My animation does not work properly when I play it on my custom rig, for an example, I made two simple animations of jumping to my custom rig and to the default roblox rig, on my custom rig the torso does not move when on the default rig the torso moves up and down. Every part of both rigs not anchored.
I also think theres can be problem with rigging, but everything seems normal, theres MOTOR6D between humanoidRootPart and torso, so I dont really see a reason for that kind of problem.
Appreciate your help!
