I'm working on a proprietary project that has lettering with a white rectangle overlaid in Screen mode at about 35% to convey the idea of a metal surface to the viewer (similar to how the apps launch buttons in iOS have that glossy sheen). My question to you all is, when I have worked on the design in Illustrator and pulled it into AE the white box in Screen mode is visible and affects the layers below.
Now, I thought there was a way to isolate blending modes to groups or layers, so that anything outside of that group/layer would not be affected. Is this correct? My workaround at the moment is to boole the box so that the screening geometry fits to the lettering, — an arduous process. Attached is an example of the effect I am going for. Ideally I'd like to keep my screening box whole so that I can play with the angle of the faked reflection without having to go through the boole process again. Make sense?
