Material Editor, Custom Curve Interpolation

Development Programming & Scripting

Hi there,
is there a way to use a custom curve as interpolation between two values within the material editor?
The only thing i found was lerp, but i need a curve like this:

I am not really fluent at math, so some help would be really appreciated :slight_smile:

Kind of old question, but in case anyone runs into this:

The following function yields Quad interpolation: clamp(ttt*(t*(t*6-15)+10),0,1) - given a value of t between 0 and 1
The curve looks like this:

And the Material function looks like this:

EDIT My Function has a mistake in the graph - the argument at the bottom most left should be a 6 not a 5.

Yes, you are absolutely right. In addition to your answer i would suggest to use a custom node. You can just paste the interpolation function needed (Quad, Exponential etc.) in a custom node and use the parameters of the function as inputs.
