@darragh
plz write your code into the code-tags, it makes it a lot easier to read

the second thing: i guess you use chunkled terrain...rename the terrainmodel, so taht it ends with "_n"
If that dont help control the size of your terrain...it should be 33x33

if u copied the script exactly from the aum there shouldnt be a error in the script :]


btw: that are just nice waves, if u use a shader 4 it ;P
