Importing Custom Pathing Maps

I can't seem to find the pathing textures with my MPQ extracting programs, my guess is because they all seem to be .tga

anyways, I've been importing textures I've made and think that to make them actually work they need to be a specific color, tell me if I'm wrong with that.

Any information on getting custom pathing maps to work would be much appreciated :)
(such as the specific color they need to be, or some of the pathing textures)

Would be really awsome to make water-pathing enablers to, a lot of fun things could be done with that.

As for water: I have NFI how they implemented water pathing, but, I do know the way they did it is horribly fucked.

you can make terrain water-pathable by SetTerrainPathability().

All right, thanks for the help :)

Thought the universal pathing blocker was a shade of gray, white makes a lot more sense. ever thought you could block ground and air but allow buildings, that's pretty cool.
