How to create models in XSI and other 3D applications and make them work in Battlefront 1 & 2. Post models, tips for application usage and share anything XSI, 3DMax, SketchUp, etc.
I'd be willing to bet that you're tiling too far from the UV origin. Image below (not to scale):
As the corners of your UVs extend farther from the origin (black dots in picture), you run a greater risk of this UV tearing you see to occur. Either split your tube up into smaller segments (and bring them in closer to the origin) or simply tile your image less (it really doesn't need to be as heavily tiled as you have it).
