Hi everyone,
in UE version 5.5.3, I managed to get the impostor baker working thanks to this thread but when I bake it, the AO channel is completely white even if the buffer shows some info.
Did someone find a solution?
So if you go to the ImpostorScene blueprint this blueprint is what indirectly contains the material used for capturing specific GBuffer render targets and sets the overall environment that will be used during the capture. If you go to the SceneCaptureComponent2D on it, in rendering features > Ambient Occlusion you will see that INtensity has been overriden to 0.
When I set that to 1.0 then AO started to bake correctly for me in the output. I still dont know for sure why it was overriden like this, my intuition tells me to avoid some sort of undesirable effect with lighting during the capture but I still dont know for sure. If anyone figures out it will be useful to know for sure.
