I keep getting this happen to me every time I model a distant terrain.

Any ideas?

you have autosmooth on?

[042nrogera2]

Yep. Autosmooth is off. I noticed that half of the model is fine while the other half is messed up.

maybe meshparts are uvmapped on top of eachother?
Not sure if it would matter, but it does on some EA stuff

I've tried a brand new mesh and still have the same problem. Could it be that I have too many polys in one group?

i doubt it, i dont know enough of worlds to help you out i am afraid.
Just make sure its properly uvmapped, other then that i wouldn't know(has it bones/joints?)
