Thanks for the pinning tip, that worked nicely to display the HLODs in-editor:
Following the mesh and material references for the HLODs, I found that they’re using the default FlattenMaterial_WS_Normal_VT material. In the material I was able to change the colour output, confirming it is what I’m seeing:
The only place I found a HLOD material setting was inside the merged HLOD layer I’m using, but changing this didn’t affect the Flatten material reference. You mentioned that the landscape settings have their own HLOD settings, so I assume they’re controlling it.
Unfortunately I couldn’t find any HLOD material reference in the details tab for my landscape, are there any additional landscape settings somewhere else?
This feels a lot closer to a fix, thanks.
