How Do I Query Directly from Animator Controller on The Transform That Is Being Fed To My Bones?

Let's say the animator controller is at work, and one of my bone, e.g. "arm_L" is being override by custom script so its transform doesn't represent what's being fed from animator controller.
Now, I want to know what's being fed into it from the animator controller from that very frame so I can do my thing in script. Is it possible and how do I do it?

 

You can look into Animation C# Jobs.
It allows you write an Animation Job that gives you access to AnimationStream and more importantly AnimatiionHumanStream which you can use to access the input transforms data at runtime per frame and modify it as you like. Then you can can write a Animation Job Playable that can be played using the Playables API

 

thanks for the tip I'll look into that right away.
