actually I'm doing a 3 point loop, so i need the duplicate layer to blend with the background in the main comp as the original is doing with collapse transformation on.
I have a pre comp with collapsable transform on because i need the blending modes inside the precomp but when i duplicate it add a mask to it collapsable transformations doesn't work anymore. Im creating a loop so i need the duplicate to have the same blending modes as the original. I tried to use a track mat instead of the mask on the layer but this also disable collapse transformation.
Is there a way to use masks on layer without disabling collapse transformations ?
