Help please! =)

Ok, i made a model with autodesk 3ds max. made a .mdl file of it then convert it to .mdx when i import it to warcraft 3 world editor it is invisible...

how can i fix this? it is invisible ingame and in the map maker. it doesnt have a texture. restarting the map maker doesnt help. i followed a tutorial but it doesnt work for me. please helpzz

i used materials from autodesk to paint the model. maybe it could be that w3 map editor can find this materials. how can i import them to w3 map editor? i dont have a file of it? they say i have to import the skin to. how do i get a skin of it? i want to keep it the colour i made it with 3ds.
