How do I get a colored object to glow on white? Emission works great when the environment is darker, but I'm having trouble getting a colored object to show up on my white surface. I tried lowering the roughness, but that ended up making it look more like a reflection. I know it's not realistic, but it's the effect I'm trying to go for.
This is where I'm at:
Switch the render engine to Cycles and Emission will cast light onto other objects as expected.

In Eevee, shift+A Add 'Light Probe' &gt;'Irradiance Volume'

Scale it up so the inner bounding box surrounds the scene.
In Render Settings under 'Indirect Lighting' you'll have to 'Bake Indirect Lighting'

In this image I've already baked it so you can see the result. Hope that's what you're looking for.
