I'm working on my first After Effects project and would really appreciate any help.
Everything was working fine and now none of the transformations or effects I add to the layers of newly added vector files want to work.
They are visible when I open up the comp for the vector file, but they aren't rendering in the main comp.
Any ideas on what could be wrong? I probably disabled something by accident
Nobody can tell you anything without proper system info or other technical details like what version of AE or for that matter what kind of "vector layers", comp details and so on. you are throwing around a lot of vague statements.
