So there are several problems I keep coming up against....first off, when I import the terrain (the tiff file) it seems to either flatten it or cut off parts of it (it's hard to tell, but I can tell it isn't right)....now, if I exit, re-edit it and push "reset" it suddenly looks right (although with a few, especially the Mount Saint Helens preset, still seems stunted)....all the tutorials I've watched never mention it, so I wonder why my version does this....the next problem is texturing....I've followed several tutorials about this as well, and feel like I've followed the instructions to a T....and yet most of the time the material distribution I use, based on the main selector, doesn't fit correctly....technically it's not a selector I'm using but the Tiff file itself, but at least once when I used it it worked fine....

Can anyone help?....
