I needed an IK solver, this solves IKs. Simple as.

tried it after struggling hard with Unity's Animation Rigging which seems simple in videos but is complex while using. Kudos to Developer.

It really helps to grasp the concept and it's easy to adjust the script. I managed to make a walking controllable crayfish which can jump, run, climb, ...

The IK part works great! I have been looking for something like this. But... when I use it on my model, it completely messes up the leg mesh and resizes it and makes it all wiggly.

i have some weird bug with the pole but exept that for a free asset i am surprized

Really simple and working good, end of the day it will be useful. But! there is a big problem. For example in runtime, i am setting hand positions and rotations, copying it, stopping engine, paste then fixed coordinates, play the engine for looking is it ok? No it moves default coordinates. Why? is anybody living this situation? 1- JUST get target transforms original localpos and localrot to vector3 and quaternion before Init(); 2- in init reset target position and rotation than bottom paste values tagret.localposition = originalPosition, target.localRotation = originalRotation; you can check my code, look at //EDITED: https://justpaste.it/cg3fi

This works 1000 times better than the built-in animation rigging. But I would like to see kinematics displayed in the Animation window when animating

I've tried a variety of IK solutions.. You'd be surprised.. Fast IK is the only solution that works with other ragdoll&bone physics assets, thanks to supporting changing the execution order. Lifesaver! Wish I tried this first

Easy to set, works fine, as a free asset, it's very nice.
