.Map :: MoHAA Mapping

Hi gang,
any idea where i can get the rogue plugin.
Have built a prefab for my map and there is big shear of white through it for some reason.
Was playing around with bending shapes and i feel it is a face or texture or something and i now cant use that prefab

That means that there's something wrong with the texture!

Its not visable in the editor but is during game play
how do i find it
