I have a simple rig built on a shape layer with copies attached to a slider. When the copies is a non-integer the newest copy is not completely opaque until getting to the next integer. Is there any way to correct this?
I ran into this a while ago so it may have been updated but I think opacity numbers MUST be whole integers when coming in from an expression. That's why you can't manually set something to say 55.5 opacity.
Along with Michael's suggestion, you can also use .floor and .ceiling methods to clip the decimal off and return the next lowest or next highest whole number.
