This will seem pretty basic but pls help a newbie learner!
I've created a logo using type and a shape (put simply). Ive transofmed the type to my satisfaction and created the shape that is to be added BUT its in a different composition and its in line form on a white ground - i need it cut out/masked so that it works like the type does ie like a letter that can be scaled, transformed etc so it eventually looks just like one of the letters. Adding the rendered shape as a layer just plonks a white square onto the type and masking it just masks the white square not the graphic. How do i cut it out pease?
Every new user wants to have fun with AE right away, but please, please, PLEASE don't try jumping into the deep end of the pool. You'll only end up frustrated because you need a LOT of basic AE knowledge to use it properly.
So do like every AE user has to do. Start with the basics:
Dave is right. You really should go through that stuff.
In the short term, if you don't want the white "ground", turn off the white layer. If that's not the right solution, we need more info. Though, really, going through the resources Dave linked will solve this problem and many others in the future!
You need to read up on track mattes and masking. The proper technique depends on the graphic.
