question about uv mapping

[meliritos]

hello all. i modelled some units for total war and i tested their mapping with a 3d max render to see if everything works alright and there is little distortion of the skins. In the 3d max render everything looked alright but when some fellows tried to put the units ingame the skins appeared all stretched out. I ask all you 3d max experts, can there be no stretching when i test them in the max viewports but a lot of stretching when i put them in game? Shouldnt the 3d max renders and the skins in game appear the same thing?

To demonstrate what im saying:
this is the 3d max render



little stretching ok?

and this is the ingame screenshot



see the problem?
