I am not sure about MGDRAW, but I think it could be dangerous.
The proper way to modify the directional cosines of a particle
is by means of another user routine, USRMED (see details in
Chap. 19 of the Manual). It is activated by option MAT-PROP with
SDUM = USERDIRE. It can be used, for instance, to
implement some sort of albedo reflection at the surface of
a given medium. However, it cannot be used in vacuum.
Sorry if this does not answer your question directly.
