I’m very close to what I want but not quite there…
Here’s a test setup of my interior with a single glowing light using an emissive texture - rendered in Eevee with an “Irradiance Volume” around the room. Notice the walls flush with the light are actually darker than the wall further away.
If I switch to Cycles (default settings) I get this lovely render in the viewport - THIS looks realistic. (Side note - I had to move inside the room, since backface culling doesn’t seem to be working, even though it’s enabled in the cycles renderer- not sure why that is!)
But if I render using Cycles, I actually get NO global illumination!
So I have 2 questions;
- Are there any tweaks I can make using Eevee to make it fill out the light on the closer walls more realistically?
- Why doesn’t the Cycles render look as good as the viewport?
Here’s my Blender file:
