Automatic tracks collector for DrawTracks

Dear Rooters
As far as i remeber there is a posibility to force trasport engine create TGeoTracks for vizualisation. But i forgot what i need to uncomment in TGeantTGeo (if correct ?) to do so?

Hi Kiril,

It is the line:
//#define COLLECT_TRACKS
in TGeant3gu.cxx
You can also add a -DCOLLECT_TRACKS in: config/Makefile.linux to CLIBDEFS

Cheers,
