[Client] Custom Models - Weird Streaming Issue

[Torque]

I've noticed that when looking at a custom model from the East (Facing West), the model seems to stream in much later then when approaching it from other directions. Anybody else noticed this and is it a model issue or a SAMP issue? Wondering if there's a solution to this. I'm no expert with custom models so wondering if it's something I need to change in Blender.

Thanks.
