    Invalid numeric result on rotation?

    caiweno9227329

      Hi All,

       

      Thank you for taking some time to read this. I installed AE 12.2.1 and Buik 15.11 to do my school's project. When I try to IK my character's leg, I was prompted on the following error. The reason why I didn't update to AE 2017 version because apparently all my school desktops haven't been updated to 2017 version yet so pardon my old version.

       

      Is there a way to fix  this issue? Any help is greatly appreciated.

          Sure. Fix the expression. It tells you everything you need to know in the warning. You might want to advise the DUIK people that they need to fix their messy code, too.

            Without seeing the expression it is pretty hard to diagnose. Somewhere in the expression you have a situation where something like this exists:

            one_value/another_value equal to zero. I suspect that you are using rotation as a divisor and when the rotation value gets to zero, which is easy to do, the math error pops up. The math error may be able to be fixed by multiplying by the reciprocal or by using an if statement. It's hard to see without seeing the expression.
