I am creating procedural clouds in Blender Cycles as shown in this tutorial: https://www.youtube.com/watch?v=Ba18cwDSAsk
After that, I would like to create a series of them, so as to generate a tileable picture, using an addon from stuffmatic
The problem I am encountering is that the procedural cloud material is still "opaque" somehow, it blocks the view from the cubes in the background, as seen in the attached screenshot.
I played around with the nodes, tried to put a Translucent and/or transparent node in the "surface" output of the shader, but it didn't work. I also tried masking the cube somehow to keep only the volume but I didn't succedd either... Also tried changing some camera and rendering options but didn't help either.
It sounds strange that volume only materials have opaque surfaces, anyone had this problem before ?
Any hints are welcome :) Thanks for your help.
