Can´t increase foliage density // Static mesh bounding box too big?

Hey there,

I´ve been having a really annoying issue when trying to paint static meshes as foliage, where I can´t increase the density high enough: Even at the max density of 10000, the meshes are still way too far apart from each other.

I´ve checked the static meshes and I think the problem is related to the bounding box, as that is a lot bigger than the actual mesh.

I´ve previously changed the mesh scale using the build settings, but I´ve also tried externally rescaling the meshes in my DCC and then importing at normal scale, but the bounding box is still off.

Any idea how to fix that and if thats really the problem with the foliage density?
