Well, before, I had a terrain and it was shaded with the "shaders01.wdl" script. It had grass, ground, etc. Now, I am using a different computer and when I run the game, it immediately closes again.
Without the script, the terrain is blue and pink. Can someone help me?
Also, Before, the terrain had different textures on different altitudes.
Now, it has different colors (blue and pink) on different altitudes.
I am really desperate at the moment, so please help.

I think it's called a multitexture shader. I'm not sure though.

PLEASE?

Maybe your other computer, where it does not work, has a very old graphics card which does not support multitexturing.

Maybe take a look at the specs of your two computers.

But even published, it does not work on the second computer

Well if Thunder is right...then it wont matter if it is published or not...if the graphics card does not support it. How old is the other computer? do you know what graphics card is in it?

have you put it back on your other computer and tried it there as well after you found out it did not work on the other computer? might be missing a file or something...we need more information

Yes, I think that its the new computer having a weak graphics card, because its a laptop.
Silly me.
Thanks anyways,
