As the title says, I’m using world compostion and I’m trying to generate LODs for every tiles of my world.
In the past, you had to get a Simplygon licence to merge static meshes into the landscape LOD, so generating LODs was only converting the landscape tile in a static mesh without using the static meshes on this landscape.
Now you don’t need Simplygon, generating LODs doesn’t only convert landscape in static mesh but is building a static mesh by merging all static meshes on this landscape.
The problem is I obviously don’t want my 3000 static meshes on a landscape trying to be merged in a single static mesh because :
- It takes way too much time
- It eats so much memory that the editor fill my 32GB of ram, then crash to an out of memory error
- Who wants to get any small prop to be merged in a distant LOD ? This is useless and add more polygons for nothing.
I looked almost every setting and I can’t find any one to exclude one or all static meshes from the LOD generation and only generating static mesh LOD of the landscape.
Is it possible?
I even tryied to look in the source of the engine but didn’t find anything.
I noticed there’s a “include component for HLOD mesh generation” in details of static meshes but it looks like it’s only for HLOD generation as switching it to off doesn’t change anything.
