Lumen & Stencil Layers in Movie Render Queue

Hi,

I’m trying to render still images with actor/stencil layers (masks) in Movies Render Queue.
I’m using Unreal Engine 5.1 with Lumen, with a Manual Fixe Exposure in my Post Process settings.

The image rendered with stencil layers appears very dark compared with the one without any Actor/stencil Layers:


*In this exemple, I’ve masked some element in the render… The image on the right is a lot darker…

Even if I try to boost the Exposure, the Lumen GI still seems dark… Any idea why?
I’m trying to get a similar result in both images.

It was working well for me in Unreal 4.27 with baked lighting.

Thank you for your help!

I’m having the same issue. My guess is that the problem lies in when the stencil gets applied in the rendering pipeline. If it gets applied before Lumen has done all its GI calculations then it makes sense that Lumen GI doesn’t see the objects that get stenciled out, hence them not bouncing light around properly.

I’d also love to know if someone has figured out a way around this.
