Hi. For months now I’ve been looking for some kind of library, plugin or whatever to get decent IK into UE4, without much success.
It would be so much more useful, if you simply added rotation limits to the bones/joints for FABRIK and for Two-Bone-IK.
Two-Bone-IK also needs a target-rotation for the hand/foot.
And those limits could be read directly from the skeleton/physics asset, because they would basically be the same as for a ragdoll.
There’s probably more you could improve (like “weighting”), but this is absolutely essential. What good is humanoid IK that doesn’t look natural at all?
