This is custom hd textures for mod ESHQ (evil scientist head quarter), update.
Installation: put it in your eshq "valve/materials/common" folder. If you dont have materials or common folder, create it. Change if necessary your config file (host_allow_materials "1" should be in there).
Make sure your settings are ok (allow materials should be checked).
I also have some hd customised models for this mod, they will possibly be uploaded in the near future.
Differences in this update: added some more textures, changed some.
