I have taken an eps file, put it in a composition and added some scaling and transforming effects. At this stage I have clicked the continuous rasterisation switch and all is working fine. The Vector shape has sharp edges.
But I would like to bevel and extrude my logo. So I need to change my logo into a Shape Layer. However I can now no longer click the C.R switch. It's greyed out. When I turn on Ray Trace 3D and add effects and lights, the edges on the now shape layer look stressed and rough as if the C.R switch did nothing.
