Q:

Hide mesh light source but keep the light it EMITS using EEVEE?

I've made a mesh that has an emission shader and I'd like to hide the mesh but keep the light that it emits. Is it possible? I know it's possible in cycles. But I wish to know about EEVEE.
I've tried using the 'hide from render' ( in the outliner ) button but it doesn't work.

A:

You can do it with a shader like this - This will exclude the object from visibility, but will allow the cast lights and shadows to operate. However, since you are using an emission object to cast your "light", you will need to bake the lighting from it using an Irradiance Volume, before it will show up in the render. Also - remember to set the Blend Mode to Aplha Clip.

To get the full effect, make sure to enable "bloom" in Render Properties.
