In the video, you can notice that when rendering the normal game view, the ambient occlusion (AO) disappears as I move further away. However, when I switch to the material AO view mode, it doesn’t fade with distance. What could be causing this issue? Why is it behaving this way? I’m using Lumen, and I disabled static lighting to make material AO work.
In the normal game view, Lumen calculates AO based on screen space data, which naturally fades with distance because it relies on visible geometry. As you move further away, details get smaller on screen, and the AO effect weakens or disappears since there’s not enough screen information to generate it accurately.
