The static mesh can be as complex as you want, but remember that only one static mesh is allowed.
The dynamic(non-static) bodies can only be built from primitives, that is spheres, boxes and capsules.
However there is no limitation on how to use them so concave shapes is allowed.

You feed tokamak with the triangles you want it to do collision-checks with so if you only want collision with a couple of triangles,just send those to tokamak.
And again, this only works with the static(non movable) mesh.
