I extracted drg’s auto cannon, and the gun and arms are separated models.

When I try to get them into unity, something wrong happened, I tried a lot of methods. Like using script to attach, using Position constrains and rotation constrain, but still can’t fix this issue. I even tried IK, not working.as well.

In my case, I play the running animation in the arm and the gun was not playing animations.

This is the video can show my problem.

Nvm I managed to solve this by myself, in the import setting, the animations are compressed by default for some reasion, I have to disable it to solve this.
