I do apologize for reposting this on the forum as I have already asked it in the answer hub, but I’m kind of desperate to try and get to the bottom of this problem.
My original question:
So, as the question states, I’m building a world with World Composition enabled. I imported my tiles from world machine. Everything looks fine.
I used the foliage brush to paint some trees.
Now, what I’m trying to do is to create LODs for my map. I go to the levels list, select a level, then I click on the icon that says “Summons level details”, and it opens up.
When I click the “generate” button, it works. It creates a simplified version for my level (tile), it loads at the correct distance, and all that.
**But the problem is, **the simplified level doesn’t have any foliage instances I added via the foliage brush (or even the procedural foliage tool).
This does work for meshes! If I put some static meshes directly (even the very same trees I used with the foliage brush), they’ll show up. They’ll be simplified and all that, but not the foliage.
As a result, all nearby tiles that are LOD0 have trees as expected, but if I look further towards areas that show LOD1, the landscape is barren. I move closer to it until it loads LOD0, and boom, all the trees are back.
Some things I tried:
- Downloaded an earlier version of Unreal Engine that still supported simplygon, and downloaded and installed the simplygon plugin, checked that it was loaded and all that: The same exact result. Will generate levels, will simplify static meshes, no problem, but not foliage.
- I tried using the “Bake foliage to landscape” option, but it leaves these weird smudges where a tree is supposed to be, so not much success there either.
- I tried all kinds of meshes. I figured maybe I’m missing something about the mesh, so I tried trees from different packs, and even used different meshes with the foliage tool. Same result.
- Tried adding trees via the procedural foliage tool. Same.
I guess I don’t get any answers because this is probably a very niche problem, so not many people had any experience with it, but if anybody knows anything about it, if you could give me the smallest clue so I could continue researching it, it’d be highly appreciated.
Or perhaps I’m doing something wrong? I mean, I could in theory add trees directly as static meshes, but I don’t think this is the right way.
Anything, any hint, any opinion, a direction to look into.
Thanks in advance!
