I have created an icon, and I want to tint half of the image to make it darker.
I have created another layer ontop of the icon, so that it covers half of my icon, and decreased the transparency. How do I get that rectangle to take on the shape of the icon, instead of it remaining to be an rectangle?
Start with your icon
For the example I copied the circle becuase I wanted the shadow to fit inside the circle. I placed the transparent triangle on top of that circle.
Open your transparency window. Select both objects and click create mask. I also check “clip” & “invert mask”
