bot_sync - Synchronizes the normals of all facets within a BOT primitive so they
are all in the same direction.
bot_sync {bot} [bot2 bot3...]
Synchronizes the normals of all facets within a BOT primitive so they are all in
the same direction. When viewing a BOT with the MGED 'e -m1' or 'draw -m1'
command, if some of the exterior facets are black and some shaded (red by
default), this indicates the black facets have their normal in the wrong
direction. To correct this, it is recommended to first run the commands
'bot_vertex_fuse' then 'bot_face_fuse' followed by 'bot_sync'. If the result
is all exterior facets are black, then use the MGED 'bot_flip' command to
reverse (i.e. flip) all the BOT facet normals. The result should be all
exterior facets become shaded.
