When I do the retargeting process everything looks fine, even the retargeted animation plays correctly in the viewport, but when I use it in my character it’s like the hips does not move with the rest of the bones. (IMG #2).
Any idea how do I fix it? I already tried checking “EnableRootMotion” in the viewport, didn’t help.
First of all, pelvis is the basis of the charscter, so it should almost always be set to Animation Scaled.
You should take care to never scale the pelvis during animations anyway - but thats different from the settings you need. Setting it to just animation will work for almost all projects where the animations were made without scaling the pelvis.
Second, the IK bones can all be animation scaled, since they arent to be mapped to anything on the skeletal mesh.
Third, the rest of the chains can either be set to Skeleton for something retargeted, or Animation Scaled for characters you animated directly without retargeting.
Next.
The only reasons that your hip is off in game is that something else is causing the legs to move out of place.
Maybe IK, maybe a badly layered blend space. Either way something that is applied at runtime.
This being your project and all, if you don’t have a clue what this runtime behaviour is from, you need to go back to the learning process…
