I captured a room via photogrammetry, i need to keep the lighting from the room (wasn't shot with flat lighting for re-lighting, I want to maintain that lighting so it will match captured footage.
Currently, I have the texture on the room's emission channel
For objects placed in the room -- they don't really cast shadows because the surface they are contacting is essentially self-illuminated.

Is there a different process I could go about making this work?

Thanks in advance for any ideas!

Render kernal “Info Channel” and then “diffuse filters”.
I think that is what you are looking for.
