Hi, I need some help with some simple material math’s that I’m struggling to visualize before me.
I wish to merge two opacity masks, one is a simple 0 to 100% gradient, another is a textured mask.
My goal is to basically subtract the darks from the gradient to the mask, and add the lights, so that the mask blends in along the gradient, cutting off completely in one end and becoming 100% solid in the other, while retaining the texture in between. Like how landscape treats height masks while painting with a gradient brush.
Multiplying them together gets me halfway there, so that everything gradually goes white, but it does not remove the darker areas from the textured mask, so the white of the mask is still fully visible at the black end of the gradient. What else should I do?
