Does editing an mdl modify your warcraft game or just map?

i've thought of changing an mdl.. and know nothing really about them, but before i start i'd first like to know if this is going to screw up my game? cuz i dont want to mod my game.. i just want to mod my map only because i play warcraft on bnet all the time with random team ladder..

also if it messes with the nature of the warcraft 3 game than that means that wont other people have to modify their warcraft game to play my map to see the model changes?

i just want to keep it strictly map-changes so that anyone in this multiplayer map can download on bnet and play instantly without them doing anything special on their end.

Importing an mdx file into your map will not affect your game, it will only affect your map. As I said to you yesterday in the other thread you posted, you would be well advised to take a quick scan through some of the tutorials in the modelling and animation forum, if only to get a feel and understanding of what you are getting yourself into. - And as I said, think about it this way, people play games like DotA and ToB, each of which utilises numerous custom models - if you have played those maps, then surely you can see that your game itself has not been affected.

oh, i keep thinking that that some mods require the game to be edited. i remember back in warcraft 2 there was a starcraft mod that required an overhaul to the whole game.. so if you wanted to play it again normally, you'd have to reinstall.

warcraft 2 and warcraft 3 are much different so no editing an mdl and reconverting to an mdl doesnt affect the game it affects the map the mdl is imported into
