Is this a bug, altering the height of the clouds, changing acceleration cache or any other parameter has no effect. Removing the twist and shear shader and it's OK

I suspect adding the Twist & Shear shader turns the clouds into a terrain based shader. But Matt et al would know better.

"They laughed at Galileo. They're laughing at me. Therefore I am the next Galileo."

Nope. Galileo was right for the simpler reason that he was right.

We need more masking methods so this could be done with something else than just image map shader or is there a way to do this otherwise? I tried but lots of other ways but so far no success. Also a way to make a gradient map from f.e. heightmap would be nice

Once I saw this technique in action (about an hour ago), I realized it may apply to another idea I've wanted to test for a while.  It worked!  Here are the results.  Many thanks for pioneering this.

WOW! Care to elaborate on how you made this work moodflow? Looks fantastic.

Its just like mHaze's method, but instead of viewing from the top, its viewing from the bottom.  MHaze's method was proof that you could create "terrain" using clouds. 

I put the sun just below the horizon to underlight the clouds for additional effect.  This only took me about 15 minutes to assemble and about 5 to render and came out 100X better than I thought it would.

I've seen such clouds hundreds of times for real, now I can finally make them!
Howgh!

here's another clouds from underneath

I found this incredibly helpful for conversion from a TER file to TIF - http://koti.mbnet.fi/pkl/tg/TerraConv.htm
So this is Disney World.  Can we live here?

Cheers Calico - I've had trouble finding this.

I had to convert the 16-bit TIF to JPG before I could get it to work.

mhaze (and all those joining in) - Thanks.  This is so much fun!  It works!
