i just converted the script i didn't add extras.
I know, I don't want to sound as if I complain!

For using the script with any model you like you have to find a way to get the xyz position of uv coordinates. everything else is easy. I will look into this in a few hours ('tomorrow')
That's great. If you find a way to do it, that's fantastic. If it costs too much time, you already got the terrain part running. Thank you for that very much.
and why don't you like the idea of materials? it's a ffp effect, so it'S aviable with every version and isn't more complicated than the normal engine materials (which are in fact also ffp shaders afaik)
I thought it restricts to a certain uv-mapping which wouldn't work with the individual uv-layout of the most models.
