| ''%%Centre%%'' is usually close to the mesh’s centroid, and appears to be the center of a sphere used for certain kinds of collision testing. | ''%%Centre%%'' is usually close to the mesh’s centroid, and is the center of a sphere used for certain kinds of collision testing. |

| ''%%CollRadius%%'' appears to be the radius of that aforementioned collisional sphere. | ''%%CollRadius%%'' is the radius of that aforementioned collisional sphere. |

| ''%%NumNormals%%'': If positive, it is a number of normals in this mesh. If negative, it is a number of vertex lighting elements (''%%abs%%'' value). | ''%%NumNormals%%'': If positive, it is a number of normals in this mesh.

| ''%%VisibilityBox%%'' and ''%%CollisionBox%%'' boundaries is always stay axis aligned even after applying tr_room_staticmesh::Rotation (always have 90 degrees step). Additionally, the test whether to rotate the box or not relies on the mesh’s rotation being an exact multiple of 0x4000 (aka 90 degrees). If this is not the case, the box is not rotated, which results in wrong collision checks. | ''%%VisibilityBox%%'' and ''%%CollisionBox%%'' boundaries is always stay axis aligned even after applying tr_room_staticmesh::Rotation (always have 90 degrees step).
