Hi guys- I have a logo design that I want to animate on. It has curved sections that I want to "paint on". Normally I'd just use the Writeon effect, but I also want to be able to scale or zoom out of the shape plus have continously rasterize on to maintain sharpness. I can't find a technique that will work the way I want, once I make the shape 3d. Is there an easy way to do this with a mask? Here is what the shape looks like:
Yes, you can do it by animating your mask as alpha channel for the logo curve. You need only to precompose mask with logo layer, and then make it a 3d. You will be able to continuously rasterize it still.
You can achieve write on effect with a shape layer drawn on above your curve and applied stroke after. this stroke can be animated and used as alpha.
