Hi.
I'm trying detect if mouse is under mesh or meshpart and if it's clicked like in Model Editor. Somebody could tell me how i can do it?

Please take a look at
Mesh Cuts.h
Bool Sweep(C Vec &point, C Vec &move, C MeshBase &mshb, C Matrix *mesh_matrix=NULL, Flt *hit_frac=NULL, Vec *hit_pos=NULL, Int *hit_face=NULL , Bool test_quads_as_2_tris=true, Bool two_sided=false ); // 'two_sided'=if mesh faces are two-sided
Bool Sweep(C Vec &point, C Vec &move, C MeshRender &mshr, C Matrix *mesh_matrix=NULL, Flt *hit_frac=NULL, Vec *hit_pos=NULL, Int *hit_face=NULL , Bool two_sided=false ); // 'two_sided'=if mesh faces are two-sided
