the snow has a bad repeating problem, but looks like it tiles quite decently (in terms of how the tiles are laid out). One idea, that i had when you sent me the grass files, was that the textures seem to be (the original ones) a solid color with specks all over it, perhaps you could go with a not solid but low noise texture like you have with the sand, then draw full on details over the specks, that dont rly matter which way they face (preferably not on the edge of a texture). gimme yer thoughts on this.
As to the highwind issue, texturing one of the games models that dont have textures is something i want to look into, but you'd still have to export the model and unwrap it, because not having a texture, there are no uvs. for something blocky like the highwind... make a new one
I will be experimenting wtih this concept for summons, as it would save a ton of time modeling, (and the models arnt that bad to start with)
