How do I hide an emissive object but keep its affect on the global illumination?

I have some static objects in my scene with emissive materials:

Is it possible to hide them, but still have them cast light into my scene via Global Illumination?

Thanks in advance!

I am to interested how to achieve this, hide Render Source.

If anyone knows how please share.

Just set a new layer “Emissive” to the emissive object, then in main camera → CullingMask un-select the the new layer.

@dskeith set Alpha of Base Map to 0. Worked for me.
