Why can't I use put Render Layers in a node group? (Compositor) When I try to create a node group that includes the Render Layers node, I get an error saying it can't create a group with that node. Is there a reason why or some way around it? I don't want to have to plug the input into every single copy of my node group.
Probably because that is a group in its own. A render group. And so Blender just will not let you do that.
