Feet not moving/Legs not animated for some motions?

[chubbidust]

Hello! I didn't know who else to come to with this issue so I thought I'd look for some help here!

I've downloaded an mmd model and downloaded a bunch of motions and decided to use them in blender for fun. When I load the motions onto the model, the arms are animated just fine, but the legs often have issues and I can't figure out why. Disabling the IK and stuff doesn't fix it, either. The scale of the model and motion are the same, I checked.

Some motions work just fine, but others the legs and/or feet just stay locked in place and look odd.

Make sure the motion applying to the same model is working well in MMD, and we can not solve the issue exactly without a sample file. Thank you. 😢
