No need to apologise for sharing

Update available in Reactor now, thanks and please check

Nice Suggestion @Millolab !!
I don't know what's the algorithm for that, do you happen to know it?

Fusion includes image functions for this:
inimg:AlphaMultiply(outimg)
inimg:AlphaDivide(outimg)

Thanks @SecondMan, it all works as expected now.

Thanks @Chad, I really like the built in Image functions,
but I did notice that when you have a fuse that uses a DCTL kernel, using any of the Image functions makes the fuse significantly slower.

So I added the code to the GPU code instead, it's only like 12 lines.
Here's the GPU code:

Did I implement the Alpha Divide/Multiply right?

Thanks again,
David

Hi everyone,

When I was first making this fuse, I saw that in the After Effects "Tint" effect there is a convenient little button that allows you to automatically swap the 2 colors from the 2 color pickers.

I didn't know how to do this back then, but I finally figured it out.
Here is a little update with the button added.

Thanks again,
David
