Hi @hieblertom , @brisck1 @glitchered @Matthew.Ivey @motorsep @Miguel1900 ,
There appear to be a fix to this problem, according to the above link.
This is a commit for 5.4, but its been quite easy to convert to 5.3.2
I have put the replacement binary dll file in a new repository along with the updated source.
EpicGPULightMass Landscape 5.3.2 Patch/README.md
This has been built to work with 5.3.2
The only was this can be tested is by the people highlighted
Therefore please can you report back
This is the cross link to original request for 5.3.2 back port of the patch
Epic’s GPUlightmass - original request
Update
Feedback suggests that problems encountered with this patch are in fact due to Windows 11(Eleven) DirectX 12 Ultimate DXR drivers
There is NO official support for Windows 11 on Unreal 5
