Whoa dude!!  That mountain mat is awesome!   That whole scene is awesome!

I've been relying on bitmaps for so long...I've tended to shy away from procedurals. But that's changing...I just got AsileFX's Advanced Material Creation and am studying.....

I like your process of creating the complex mats first via layers and then mixing the resultant 'simple' mats..... I'm still struggling with proper distribution with alpha channels and trying to get the right blend between layers.

Love that Shasta water....

This thread and LMclean's thread has been very informative and enlightening....

Checking out GeoControl...the upcoming release looks very promising for Vue.

Been playing with Joe Chip's method of making the mountain ranges and it seems there are mixing possibilities for the terrain editor as well......who woulda thunk it....mountains from waves lol.......lots of possibilities with throwing a procedural on top of a grayscale..and mixing more than one grayscale together in PS before hand....

Wish I didn't have to go to work...just wanna bang on my keyboard all day lol...
