rigul64, thanks for the tip. _______________________________________________________________________________________________

Quote - And I would also go with three mixed materials instead of  snow and a two tone mat.....(or maybe you did, I can't tell from here)...mix the rock and snow with environment settings and save it. Then make your bottom mat and mix it with the one you just saved again with environmental settings. That should let you adjust all three layers separately. Make sure all mats are set to object standard or parametric...not world or the same as the above will happen.

Monsoon, The Object and World orientation makes total sense the way you explained it. Thanks! You said you would go with three mixed materials. Could you explain how to do this? and What do you mean by mixing with "environment settings"? Thanks!
