Hi.

I have run into a little problem with a morph I am doing. Basically, I want to tie two seperate morph targets to the same custom attribute controller using a float expression. . . But whenever I go to select the control in the custom attribute as the control for the variable in the expression box, it is grayed-out.
Does anyone know why this is the case, and how I should be accomplishing this if I can’t do it in the way I have tried?

Thanks in advance for any help.
