Dear Community,

I recently created a spiral staircase using an array modifier in Blender but when I exported it to Unreal Engine 3 (using an ase exporter) there was an error that said no collision model. On top of this when I tried to place the mesh into my map it was invisible. I also found that the preview for the mesh (in the generic browser) had only the first step, the step that I duplicated with the array modifier.

I was wondering are array modifiers static meshes? That can be exported to Unreal Engine 3?

And also

How do I add a collision model to my staircase array?
