Function Node Tutorial

[old_blaggard]

Some people at Ashundar were struggling with functions, and so I wrote a basic tutorial to help them out.  I hope that this will help anyone over here who is still struggling with functions .

hey thanx man....this will help a lot.....

but I am not getting the results.......what am I doing wrong....

Try getting rid of the fractal terrain for starters, and make sure your displacement shader is at 50 or 100.  I would also recommend bypassing the surface layer, as that makes the canyon less prominent and thus harder to see.
