include your textures in your .bsp file
by adding the red part in your .bat file
@echo off
hlcsg
-nowadtextures mapname
hlbsp mapname
hlvis mapname
hlrad mapname
copy mapname.bsp "D:\CSNS\cstrike\maps"
cd D:\CSNS
pause
hl -dev -console -game cstrike +sv_cheats 1 +map mapname
or you can use this one .. this is more troublesome and space demanding
@echo off
hlcsg
-wadinclude wadname mapname
hlbsp mapname
hlvis mapname
hlrad mapname
copy mapname.bsp "D:\CSNS\cstrike\maps"
cd D:\CSNS
pause
hl -dev -console -game cstrike +sv_cheats 1 +map mapname
nowadtextures is better so use that one
