Issue with landscape HLODs

[inedria]

Hey there -

I have an issue with my HLODs on a landscape. This is a 4km square brought in from Gaea, and materials are applied and blended on weighted layers using masks. Screenshots are a bit blurry on the ground, I’ve taken these screenshots from a Shipping build with RVTs in place. However, I get the same issue whether I’m using RVTs or not, so I’m eliminating that. This hasn’t happened on any other map from Gaea or World Creator, so I really don’t get what’s happening.

The issue is that one specific part of the map is transparent when far away, and as I move closer to it becomes dark, then a weird texture, then totally normal when I get close. Each HLOD transition changes the texture to something else wrong, it seems.

This is a single landscape, unedited at this point, and apart from this 0.5km zone, I’m not seeing the problem on the other 15.5km of edges…

Has anyone come across this or got any ideas? Thanks in advance!

Edit - if it helps anyone have an idea, I notice the issue is happening on the boundaries between these specific Streaming Proxies (and only these ones).

The landscape LOD doesn’t have the same HOLD detail, try increasing the HLOD polys or moving the load range further out to match between the landscape LOD and HLOD.

Thanks - could you explain just a little more, please? I don’t get what you mean by saying the landscape LOD and HLOD don’t have the same detail.

Increasing HLOD polys - Is that just adjusting the screen size LOD 0, or something else? (I’ve gone from fractional to 10 here with no real useful difference)

Load range - is that just the call view distance? (I’ve tried from distances where I can just see the mountains to well beyond them, no difference)

Thanks again!

Each color represents a different Landscape LOD. If your HLOD has lower detail than landscape LOD, gaps will appear due to differing polygon counts.

By setting up the Load Range in World Settings, you can adjust the HLOD streaming distance to match the Landscape LOD detail from a distance.
