How do IK and controllers work on import into Unity?

Hello there,

I’m starting IK bone based animations of characters.

As I don’t want to go through a 2 monthes workflow and finally see that some modifiers are not supported by Unity iPhone, may I ask you this question :

How does Unity iPhone import animations ?

Does it simply capture the transforms at every keyframe ?

Or does it import the IK modifiers and then apply them ingame ?
What if there are some custom controllers to IK chains, does Unity import them correctly ?

This is very important, as I think simple transform capture would be the very best for iPhone performance.

Thank you for your response :slight_smile:

IK and IK controllers don’t import

Unity uses and supports keyframe based weighted bone driven animation only (with interpolation naturally), it will not do any realtime IK resolving.

Thank you, so I just make my IKs in my favorite 2D app, and then export it in FBX format, and that’s all ?

Or I can’t use IKs at all ?
