Rendering in Layers

Hello

I’m looking to do a render that has quite a few human models of which each has a couple of 8k texture maps. My computer isn’t able to render all of them at one go so I’m trying to figure out how to do it render passes under compositing.

However once I activate my hdri and click the environment under the passes for the background layer, it seems like that’s all it renders… for every layer.

What am I doing wrong?
Here my composite node map

That is rather a simple node tree.
Problem does not come from Compositing Nodes Editor.

Check ViewLayer properties in dedicated Properties Editor tab and Outliner.
You may have enable the Render Single Layer option or disable collections you want to render.
