So, I really love the ability to change the different input curves when customizing my brush, but ever so often I run into a roadblock. Sometimes - especially when I’m making pattern brushes that are meant to change based on distance or time - it would be very useful for me to make a part of the curve, well - not a curve, but rather a straight line, or a ‘step’. Right now, as far as I understand, the values between the points I set in the curve customization space are based on interpolating the simplest polynomial (which I imagine is very efficient computationally) but there is no way to interpolate the values between any two points linearly, or immediately go from one output value to the other without any interpolation.
I am providing a mock-up, to clarify what I would like to be able to do.
The symbols and shortcuts I added are just examples, but I believe it conveys the general idea. Right now it’s not really possible for me to accomplish something like this, at least not conveniently or fully.
I could more-or-less get the “steps” if I only flip between 0% and 100% output, with no ability to get any intermediate values, and I think it’s technically possible for me to insert a straight line into the curve if I manually set every single point from 0 to 100. And even then it’s not gonna be perfect, since I can only set the coordinates in increments of 1.
So, yeah, while I imagine it might be a tough thing to add, since it requires messing with the some basics of brush operation, and would probably impact performance (at last of the more customized brushes), I think it would be a pretty cool thing to have. And that’s very important.
