How to make a single one piece?

[moniker 67]

I've made an huge wall with 10 holes on it where I will set windows. The texture for the wall is not a repeating 16x16 texture but a single big texture. When I load the miobject file on Mineimator the texture repeats in lines. I just want a single clean texture like when you load a cube and you are able to change the offset and repeat options. Any ideas??

 

I can add the texture inside Modelbench but modelbench has no real texturing options like Mineimator has with the offset and repeating options so I can't make the texture fit properly.
