Playing with controller editor now. It's awesome but I don't know how to invert value. I tried multiplying by -1 but this didn't work that way. For example I want to press pen harder and get small dot with maximum opacity and big dot with minimum opacity when drawing softly. How to do this?

hi poniu,

You can have a look on this tutorial who make what you want.


In substance controller are drived by a value included in a range of [0..1].
If you invert your presssure you will got [-1..0] who will be clamped to 0 and generated no effect at all, so you need to Add 1 to your result to retrieve the valid range [0..1]
In your case :
ControlledValue = 1 - Pressure

This can be directly achieved by the Sub operator when you plug your pressure on Input B and set 1 in input A


Hope this help

I got it. Thanks!
