Hi all, I have been struggling with retargeting mixamo animations that have root motion.
I have linked a video to show the issue: https://youtu.be/9yoHR_XZGN8
What I’ve done:
I downloaded the mixamo base skeleton, and copied it, and made a modified skeleton in UE with a root bone called “root” though I have also tried “Root”. Then I downloaded mixamo animations and assigned them to the original mixamo skeleton. I then went through the retargetter (exporting the files first) to retarget the original animations to the modified skeleton with the root bone. Then in the retargetter’s opstack I have tried Pevis motion followed by root motion. In the preview window I can see the root bone moving correctly! However on export, the animation loses the root motion and the animation is stuck in place.
Oddly I have also tried with the root bone named “Root” with a capital R. In that case, the animation again moves the skeleton, but it will snap back even with root motion enabled (in the animation montage) suggesting that it doesn’t approve of the capital R.
Anyone else having this issue? Or if I’m doing something wrong? The warnings about IK goals are just because the one I video’d I had turned those off in the opstack. I have tried both with and without retarget IK goals enabled and it doesn’t seem to matter.
