Hi there,
i don't know if there is a mirror somewhere, but i also realised that the wiki seems to be broken ( i just updated trinity 3.3.5a and reextracted the maps)
extracting the maps is done in a few small steps:
I am not sure about Windows, but in Linux:
1) create empty directorys in your servers data directory
#cd ~/trinity/server/data
#mkdir Buildings vmaps mmaps
# ~/trinity/server/bin/mapextractor -i <wow client directory>
#~/trinity/server/bin/vmap4extractor -l -d <wow client directory>/Data
# ~/trinity/server/bin/vmap4assembler Buildings vmaps
' quick edit, I forgot the mmaps:
# ~trinity/server/bin/mmaps_generator
Regards,
Florian
