This could be totally irrelevent.
but I thought I would add that I’ve got HLOD issue’s on a map and I think its related to using a texture data asset in a props primary slot, the referenced material is an instance of M FortniteBase Parent, with colour changes.
I think it’s related because I have another map that does the same and it’s the only thing in common
I cannot reuse the same HLOD layer, everytime I make a tiny change even a settings change, it won’t launch and the HLOD will fail a build HLOD, however making a totally new HLOD layer and building it works.
I stopped using a regular launch session with it ages ago, the push changes and the HLOD layer being funny gave me some issues.
So I’m a little sus on custom materials and the HLOD layer.
Its been quite a while since I’ve tried doing without replacing the HLOD layer, things could have changed a bit since then
