A long time ago (the files are now missing due to hard disc failing)I used the 'lava' texture to simulate lava flowing down a mountain side - and very realistic it was !!
I can't remember the coding (I think it was quite short, using U and V) and I can't find anything about it in the manual.
Can anyone help please? I think I used a lava 'sprite'
Yours hopefully, David.

PS I am using A7 and c-script
