Where would I put an expression that trims my in points? Surely not in a transform attribute like position. If necessary I can probably skip the expression, and roughly trim the layers by hand.
thanks for the reply. I solved my problem last night though. I didn’t use a custom shatter layer. Having used a custom shatter layer with the same alpha channel as my logo, my problem was solved. This did mean that i couldn’t use the glass shatter preset, so i had to create a shatter matte which i did with turbulent noise and colorama.
