Terrain issue

[KENNITHH]

Hi there,

I've got this model (.obj) which are some small hills which I fitted to match the map I'm making.

Now the problem is, when I export it as .MAP from Milkshape 3D, the size is perfect but it looks ugly & broke and it has more then 1000brushes lol

Soo..
I created a heightmap texture to make it more beautiful and texture it in gensurf but I can't seem to get the same shape out of it in gensurf as when I export it as .MAP from Milkshape so the size is way off target.

Anyone with better experience?

Thanks in advance.
