It is possible to save the deformation generated on the terrain and use it as the track default.
1) Open the file wrs/wrs.ini and add the following lines ( or just the second if the "edit" section already exists )
[edit]
deformation=1
2) Drive several laps in testing mode on a track to deform the terrain ( it's possible to use deformation_multiplier to deform it faster: http://forum.piboso.com/index.php?topic=15.0 )
3) Press left ctrl + d: a file named temp.dfm will be saved in the "wrs" directory, in the World Racing Series installation folder
4) Rename temp.dfm to track_id.dfm ( for example: holjes.dfm ) and move it to the proper track folder, with the matching TRH file
5) World Racing Series should automatically read this dfm file at track load time
interesting! thank you
