i wish we had a better control of light emitting geometry. there was a sort of hack using the falloff node in versions prior 3.04 by setting grazing angles and falloff index - as demonstrated in this video here https://youtu.be/uMckdfFdEko?t=1976 - but with the current node this seems not be possible anymore, at least i didn't find any similar trick to do so. the problem is that sometimes you want to smooth out light emission from low polygonal geometry like a cube or a geodesic sphere.

the most artist friendly way i could imagine this feature would be to simply use the 'smoothing' parameter of the emission material node for setting up smooth light emission as well. of course, some fine tuning control inside the falloff node for this purpose would be always welcome as well!

cheers

Hi 3dworks,
here it seems to work as expected.

ciao beppe, on a sphere it is working as expected. but how can you smooth emission of a cube as seen in the video?
