Hi there,

Just finished a little demo.
The focus on this project was image planes.
The challenge for me was to find a way to export the multiple passes to one exr file and in one rendering.
The main problem in this was the separation of the shadows.
You can simply resolve this with takes but then you don’t have the one file and the one rendering.
So as many as you know and discussed the way to go is illuminance loop.


Screenshots of the shader are in attachment.
I used the following shader exports.

RGBA
Surface color
Alpha

Mask
Mask.red: Diffuse
Mask.green: Occlusion
Mask.blue: Shadows

Thanks to all here and at odforce who helped me understand the illuminance loop.
Cheers,
Claudio
