No Ambient Occlusion for Trees in the Distance

[Integreater]

Hello,

i have a Problem with the Trees. The trees that are farer away from the Camera have no Ambient occlusion. Its for a Cinematic Shot, so i dont care about performance here

Information:
Trees: EuropeanHornbeam
Nanite Settings: Nanite enabled, Preserve Area checked
Material Property (Leafs): Opacity Mask Clip Value 0.1
RenderSettings: Support Hardware Ray Tracing enabled (Surface Cache), Generate Mesh Distance Fields enabled. No Ray Traced Shadows and Skylight
What iam missing here?

Check your ambient occlusion settings in the post process volume

If it’s not the SSAO view distance, which might partly be your problem, it could also be global distance field view distance which is hard capped unless you use CVARs.

Try something like this:

r.LumenScene.GlobalSDF.Resolution=500 (lower if it crashes)
r.LumenScene.GlobalSDF.ClipmapExtent=15000
r.Lumen.TraceDistanceScale=5

Thank you Guys,
i fix this Problem by using the Console Variable r.RayTracing.Culling 0 see here: Shadow Distance, I also increase the Max Trace Distance in the PPV.

I also recommend to read this, if you have similar issues:
