Similar to these questions (1, 2, 3), I wish to emit light from some of the atoms in my model. I've randomly generated some atoms to be glowing and blue. I've followed a lot of the methods of these questions in generating my own material. However, I'm not observing (rendered) any light diffusion from the blue atoms onto other atoms and their surfaces. Clearly the light source I've created is working well and creating these shadows.
All spheres share roughly the same material properties, although I'm giving any emission from the magenta atoms and so using a different material node set. I've ramped up the emission strength for this image just to show it's not diffusing properly of neighboring atoms, although ideally I have this lower so there's still some aspect of the atom curvature relative to the main light source observable.
I was wondering if using Blender 2.8 might have changed some of these properties from previous versions, as I'm fairly inexperienced.
What am I missing, to observe light diffusion from neighboring atoms?
