Lumen with Hardware Ray Tracing Enabled No GI on Shadowed Areas

[mackenziex]

Hello! I’m working to create a UE 5.0 project template and I enabled Support Hardware Ray Tracing and Use Hardware Ray Tracing When Available in the Project settings. I can see that the quality of reflections has increased, but when I go back to my scene after compiling the shaders I’m not getting proper lighting on my meshes. Please see the image below:

The Lumen scene overview is showing everything as it should look, so I’m confused as to why the materials are blacking out?

Here’s an image of my project settings as well:

I’ve been using Lumen for a while now with now issues so I’m not sure where this is coming from? I feel like it’s something related to the Lumen reflections as the materials that are more rough are not having the same issue.

Thanks in advace and I appreciate any thoughts.

Here are my laptop specs:
Intel(R) Core™ i7-9750H CPU @ 2.60GHz 2.59 GHz
RAM|32.0 GB (31.8 GB usable)
Nvidia 2080 Max-Q with Nvidia Studio Driver v535.98

So I suspect the issue isn’t related to Lumen, if Lumen is disabled the issue persists. The materials are all Substance Tri-Planar template materials, but the confusing thing is that with the same settings some materials have this issue and some don’t! Maybe an issue with the Substance plugin?

GI disabled in post-process volume.

Figured it out! The substance template was trying to pull and AO texture, on the substance materials that had an AO output it worked, but by calling the default texture for the AO it was having issues, just edited the template and chaged the default AO texture to a white texture. Working now!
