8b514bccd162Short description of error
I use a Shader to RGB after a principled BSDF to do a toon shader, it works perfectly with lights (eevee next is awesome) but doesn't take in consideration the emission of objects.
Exact steps for others to reproduce the error
Either open attached file or:
the Plane will appear black whatever the emission power, but will work properly with classic lights.
Thanks !

Hi, thanks for the report. Unable to confirm either. Can you share the viewport render result you're getting?
Hello ! Here are some screenshots and the file. You can see the plane's material which doesn't receives the light from the cube when the "Shader to RGB" is connected :)
Thanks, can confirm with both EEVEE and EEVEE-next
Emission doesn't work with the node "Shader to RGB" on EEVEE Nextto EEVEE: Emission not received when Shader to RGB is connectedScreen space raytracing is not possible on any BSDF node behind the Shader To RGB node. This is a limitation. However, they should pick up emissive object lighting from volume lightprobes.
Perhaps you can use a aov for shader to RGb, and combine it with bdsf from main buffer using composition.
