How to boost indirect lighting only with dynamic actors ?

See picture attached, the set-up is a FPS game with a highly contrasted corridor.
Very few direct lighting coming from a directional light (with dynamic indirect lighting active).

What I’d like to do is boost the lighting only on dynamic objects (The gun and the arms).
Is there a way to achieve that ?

I was hoping to boost the indirect light cache but couldn’t find a way (maybe that’s the wrong way to address that anyway).

Thanks by advance as I’m really stuck here.

Increasing Volume Light Sample Placement Scale value in World Settings may help.

Thanks Jacky, I’ve tried, it helped a little with a more accurate representation of what it “should” look like but it’s not enough.

  • You could try setting your dynamic meshes indirect lighting cache quality to ILCQ Volume instead of ILCQ Point
  • You could try adding a Post Process Volume and tweak the Global Illumination settings or add an Ambient Cubemap for some extra ambient light
  • You could try adding more windows or brighter lights in general to your scene
