I am new to the Blender community. Recently, I'm working on a school animation project which I created some animations and applied volumetric scatter in the scene to create depth. Unfortunately, due to the limitation of the renderfarm, I had to separate the scene into foreground, mid-ground, and background to reduce the workload of it so it matches the requirement of max 15 minutes per each frame.
The problem is that when I composited 3 layers in AE, layers overlapping each other. It made the mid-ground and background extremely dark because of the first layer of volumetric.
Here is the example scene without any layering:
Here is the layers that I used:
Here is the combined image:
I know this way of layering is wrong so is there any way to do it or maybe in passes?
