Instance collection from geo nodes with Altermesh in Unreal Engine

Hi!

I’m using Altermesh plugin in UE5 to import geo nodes from Blender.
I’m trying to have an instance of multiple meshes along a simple curve.
It is easy to ralize instances but not efficient at all as UE will creates polygons for each instance.
Do you know a way to instance multiple objects imported into UE? I tried to instance a simple blueprint with a random pick item but it instance always the same mesh…
