Yup that will work. But fair warning it can get slow really quickly if you have to do this a lot.

<p>I have a 3D Scene in Nuke with several cards behind each other in 3d space. Is there a way to multiply them on top of each other? Like with layer blending modes in After Effects but still keeping it a NUKE 3D scene?</p>

I don't think it's possible without doing a 2D merge on two rendered elements

Figured out a solution. See answer on the bottom.

Can I multiply 3D cards in a Nuke 3d scene on top of each other, like i can multiply layers in After Effects?
