I'am new in fusion.
I made a composition with a layer animated by a tranform node and an other not.
I wanna make a shadow of the one that don't move on the one that move.
I use for some nodes to modify the static one and give it the aspect of a shadow and put it with a merge between the static layer and the moving layer.
The moving layer is smaller than the static one and i need to have the shadows only on the surface of the moving layer. But If i try to connect the output of the animated transform of the moving layer on the mask input of the merge passing by a bitmap node in alpha mode, i don't have the shadows on the entire surface. It be cutted.
I think it's an alpha problem but i don't know how to fix it.
Do you know how to get the alpha (or visible pixel) data of a tranformed layer ?
Thanks a lot for your help.
