Let me see if I have got it right: you are using my demo (terrain + code) and it works fine, but then you do something and the code doesn't run properly anymore. What exactly do you do? Please give me as many details as possible.
the only thing that's different is I'm using my own level instead of yours, I'm even using your terrain, if I use my terrain it has the same problem + the land grows instead. Also to see my exact script I posted it a few psots back.
I wonder if you merged an animated model with the terrain then deleted it. If so, you may have animation frames in the terrain thats giving the odd behavior 'grows'.
Hmm, well i tried my whpole code in your level only changing to the level to be loaded to yours, and it works fine...so what could be the problem? why in yours and not mine. They seem pretty much the same?
PS: The terrain is def not scaled or attached to anything or animated.
