When "A" value is 100, "B" value is 0.

[PEN]

I want to wire 2 orient constraint weights to custom attribute slider like next. When Blend slider is on 100, target "A" should be 100% and target "B" on 0%. If I change slider value to 0, target "A" should be 0% and target "B" 100%.

How I can do that?

Thanks for helping.

B=100-A

This rely was to short to post:) So now it isn't.

Thanks for reply Pen.

Hmm... Max says --Incompatible types: 100, and undefined
Something is wrong there:sad:

My expression is now Orientation_Weight_1=100-Orientation_Weight_0

Are you using a wire param? Is so you need to wire to the spinner directly for both. One expression will be...

theSpinner

and the other...

100-theSpinner

"theSpinner" will be what ever track is that is controlling it.

Max says --Incompatible types: 100, and undefined

because Orientation_Weight_0 is... undefined
assign a value to Orientation_Weight_0 before calculating Orientation_Weight_1

Oh yes... Simple math:)

100-spinner value(if 100) = 0
and
100-spinner value(if 0) = 100


Now it works! Thanks.
