Counter-Strike: Source : Bot's Navigation file for the map DE_DAMAGED_BETA
Nav Creator: Meurglis3, Release Date: November 12 2015
Here is the Navigation Mesh for nice old school map de_damaged_beta by Unslord / Gary Hwang (relesed June 2007).
It's fully created from scratch and carefully hand-tuned (manually optimized) .nav-file because included in original map archive .nav-file was simple auto-gen (absolutely not playable, imho).
Approximately 90% of the all auto-generated areas were remade manually. The special attention was paid to difficult complex of vertical pathways at Bombsite B (which in the original file was missed completely).
Well... bots use all possible ways now and perfectly moves through all map. So you won't find a silent corner where they wouldn't stick the curious noses! :-)
Also this Navigation Mesh is fully Place Painted.
NOTE: For possibility of comparison and in-game testing the original .nav-file by map creator available to downloading with the same map.
Play and Enjoy! Also your responses are still important for me ;-)
