Had a few problems since re-installing Windows and AE CS5. Mask tool works, can create masks in layer, but everytime I select Roto Brush or Paint Brush and click into a layer to do something, no luck. Absolutely nothign happens, settings for the brushes are fine, just not being applied to any layer, plain solid or a picture. I am not new to AE, been using it for a long time, but rarely use AE for these features. Any ideas on how I can actually start to paint in AE?
Are you working in the Layer panel? The paint brush tools, including Rotobrush, only work in the Layer panel. Double-click on the layer, then you should be able to paint.
Thanks mate, I realised with the change of workspace, I'm used to the Text workspace as a pose to the one which it was set on I was working in the wrong preview. Also it was auto locking my layer for some reasons, but now that's resolved too. Thanks, you definately helped.
