I create 3rd person project.
Add Mixamo Anim Pack and Animation Starter Pack.
Then I do retargeting of the Animation Starter Pack to Kachujin_G_Rosales Skeleton, and all was fine.
Ok, Then I try retarget Base Animations to this skeleton… And catch strange situation:
How I can fix this?
I know this is late but it may help others having the same issues. There is a problem with the base TPS template animations and character, the TPS Template animations are setup with the root bone rotated incorrectly. The skeleton has the root bone rotated Z up/Y forward and the anims have it Z forward/Y down. If you enable “show bones” you will see the incorrect rotations, to get a good visual of it make a quick 1D blendspace and do a blend between a TPS template anim and one from the anim starter pack and you should see the weird rotation occur when you slide through the blend space…any of the idles should work for the visual or the run from TPS and the sprint from anim starter pack are good visuals too I hope this helps. Try the anims here and let me know if they work better for you: TPS Corrected Anims
Life saver!
But there is no corrected walk animation. Is there anywhere we could get that?
Sorry about that, the one provided by epic is missing a frame once we exported it so we had to make a new one real quick both are now in the file if you use the ThirdPersonWalk anim you will notice the slight glitch at the end due to the missing frame from exporting it. The animWalk is the one to use that we recreated as closely as we could to the original. Hope this helps.
If you look at root rotation it probably will be wrong
Just to help others people:
Go to your skeleton → Retarget Manager → Modify Pose → Reset.
I literally have the exact same problem in that exact same order. Knew I wasn’t the only one
