Why is ABC 3D model so broken animation?

ABC 3D model animations often appear broken due to rigging flaws, keyframe mistakes, or software/format incompatibilities. Rigging issues—like incorrect bone weights—cause unnatural movements (e.g., limbs bending oddly). Missing or misplaced keyframes lead to choppy, disjointed motion. Using the model in unoptimized software or unsupported formats disrupts smooth playback. If the model’s from a third party, check its original rigging specs or test it in the software it was built for to fix the issue.
