Raytracing. No GI on mirror raytraced reflections
Hi there. I don't know if I'm missing something in my workflow, but I can't find a workaround to make reflections look how they should on mirrored surfaces.
I'm working in a project with some clean mirrors, It seems that Raytraced Global Illumination is not working within the reflection, whatever tweaks I made on the material, post-process or Lighting elements.
Everything seems to be right, but i only see direct lighting in the mirrors, not GI at all. Am I doing anything wrong?
The issue can be seen in the picture below. The mirror reflects the walls black, while in the scene are lit by the GI. You can find the post-process rendering features setup as well.
The lighting of the scene is made through Sun & Sky + Rect Lights on windows. All them with Cast ray tracing shadows, affect ray tracing reflections and affect ray tracing Global Illumination enabled. The only thing I tweaked was the skylight intensity to 0, as far as it was bleeding a terrible blue color all around, reflections included, It looked like a fake raster effect. I post as well a picture of how it looks with skylight turned on (1). Is there any work around on a per-object or per-material basis?. Maybe through Console Commands or DX12 tweaking?.
We love the new raytracing features in Unreal, but this kind of issue makes us doubt about it's production use for archviz where pure plane reflections are often used.
Any help would be appreciated.
Thanks in advance
