These following images are individual RenderLayers from Blender that were finally composited in Natron digital vfx compositor. What makes Blender and Natron so easy to use is coming up with a proof of concept just using simple geometry and objects. Blender’s EXR multilayer can render unlimited passes, color and channels. Natron is 100% EXR compatible. Natron can read all of it channels and process unbelievable high end visual effects.
The image below is a Natron screen capture with the node graph merging all layers together using a shuffle node to extract the OpenEXR multiplane image buffers. I had later used two color correction nodes to do some color balancing and overall color grade.
