When I create a "Shape Layer" I'm unable to make any changes to the layer via the rasterize. It will not let me deselect it. The sun icon is in the box next to the shy box. The reason why I'm asking for help is any shape that I add in AE is not being effected by the rasterize and shows jagged edges in text or shapes. Do I have to select something in options for this to work? I've googled for this but I've only found info talking about .Ai files. Or, is that the only way to take advantage of the rasterize?
Here is a image on what I'm talking about. Please help if you can.
Your composition resolution is too low. You've expanded your viewer to 400% size, with the result that your pictures look pixelated. Switch the viewer to 100% and everything will look nice and crisp, but much smaller.
Adjust the size of your composition and resize the objects in it.
