Need for instant Lumen scene update

Hello.
I’m using unreal engine to render a dataset of rgb images and segmentation masks. Currently the setup consists of aranging meshes in the scene in one frame, rendering the frame, changing post process material in the next frame and rendering segmentation mask. This goes in loop where every two frames I update meshes in the scene. The problem is that lumen takes multiple frames to update lighting. I know about lumen update speed but that still isn’t enough. Is there a consol command to force full lumen update in one frame or is there a way to skip rendering in movie render queue for few frames until lumen updates.
All help is appreciated :smiley:
