Grain effect is not moving with moving shape layer

[lee jungb8564692]

Any one has a suggestion on how to make grain effect follow the shape when it moves.. Default is that when I apply a grain effect on a shape layer, and I move the shape layer, then the grain effect just stays in place and doesnt move with the shape layer... it looks like a grain overlay over the entire composition.. looks weird. Thnx!

I think this is happening because shape layers are always "continuously rasterized". One possible work around is to make a new solid, add a mask, and copy the shape layer path to the mask path. So long as you don't continually rasterize the solid, your grain will move with the layer.

More explanation of why this is happening is here: https://helpx.adobe.com/after-effects/using/layers.html

"When you apply an effect to a continuously rasterized layer, the results may differ from the results of applying the effect to a layer without continuous rasterization. This difference in results is because the default rendering order for the layer changes. The default rendering order for a layer without continuous rasterization is masks, followed by effects, and then transformations; whereas the default rendering order for a continuously rasterized layer is masks, followed by transformations, and then effects."

Thnx for the reply and suggestions @synthetick ! Much appreciated. But the thing is that the layer I want to use it on is going to be scaled up very much so I have to use continious rasterize. Or else I could have used pre-comping the shape layer, but without Continious rasterizing thats not helping me either.
