I have 3ds max and I was wondering, does unity accept HI solvers or even IK solvers? I tried looking everywhere but to of no avail, help would be much appreciated. Thank you.
No, Unity does not import IK solvers (or any other procedural animations). If you’re using IK and similar things, then please bake your animation during export to fbx. If you’re importing *.max files directly, then Unity has “Bake Animation” checkbox.
