It would be quite handy if all the pattern components had a "Lerp mode" checkbox which enabled interpolation between the two color inputs.

An example of use: currently it is not possible to make a transparent shaped "hole" in the background because of the blending. With lerp mode you simply set the shape alpha fully transparent and that would result in a transparent result too.

Well you could just have the pattern generate a black and white alpha map and use it to plug into the "lerp" input of a lerp component right? or are talking about something else?

Not so bad, just one extra component.

However I always thought they should be in lerp mode anyway... who uses it in the regular background/foreground mode anyway? It's a strange standard to have.

Are you talking about not being able to give the patterns a transparent color?
Because that annoys me alot, having to use extra components just to get a transparent ellipse or tiles or whatever, lol.

That is exactly what I mean: I expect to be able to define semi transparent something and not having it blended onto some background color (we have the blend component for that).

And Betis I'm mostly proposing this because it is annoying that you have to specify all these extra settings - its not just about the component count.

To me lerp/interpolation would be the natural mode of all the pattern components, and blending is something special (why did FF settle for normal blendmode btw and not some other?)
