shader modifier? New Shader Op! 2005-03-30 - By Peter MacDougall

Not that I'm blowing my own horn here.... ok I am. :)
I did the chapter in the Carrara 3 Handbook about terrain generation. It
is based on the C3 terrain generator and not the new one in version 4
but the principles are the same. It is a good book overall with lots of
good tips and ideas about working with Carrara and I know you can get it
at a discount as I just saw it at Half-Price Computer books locally.
In a more specific answer....
a mountain range can be generated as a single mesh or as separate
mountains. Probably the best way is to use a single mesh for background
mountains or general terrain and then add mountains that will be central
to your scene as a seperate terrain: like a "hero" in front of a "cast
of thousands". Mountains can also be stacked to create snow or scree
effects: generate a terrain, duplicate it without moving it but then
smooth the duplicate texture this with a snow shader and you have snow
nestled into the valleys. If you add noise to the duplicate instead, you
can create the effect of distant trees.
I recommend taking digital pictures of rocks, making them tileable in a
graphics program like PhotoPaint, Painter, Photoshop Elements, and then
using those with the enviroment shader and fractal noise mixers to
create textures.
In general, Bryce resources can be helpful too as the principles can
also be used with Carrara although the tools do not work exactly the same.
I hope that helps.
