Hi Victor, There is no particular reason, other than it being a demo that shows "big clumps" are possible and a use case of them. So you can use an obj mesh to replace it.
As for the physics, a clump representation offers more surface roughness, so it could lead to higher drag compared to a smooth mesh-represented surface, unless you specifically model the mesh surface to compensate. However, in the case where the drag is provided mostly by the grousers, my experience is that the discrepancy becomes less pronounced.
