I have tried the tgc associated with this and it's really great to know someone has gone to the trouble of making this happen.  My problem is that when I use the tgc it covers everything.  I'm obviously hooking it up wrong.  Any help?
So this is Disney World.  Can we live here?

covers the entire terrain?... you have to set the max slope.. in the tgc its set to 16degrees slope i think...

A new test with some fake stones layer

I've created a messy environment to see how snow intersects with other elements. I've also plugged a reduced version (with very low displacement) of the node to the stone layers, plus a lambert shader to give blueish translucency



Here is some nice feature, especially on low right and center of the image: you can see how the translucency color gives a somewhat icy appearance to many zones

However you have to pay attention to the edge softness, sometimes the intersection of snow with stones or terrain can produce strange rendering artifacts on some point. I'm trying to explain why

Very cool.  It does look strange in a couple of areas but overall it looks amazing.

I'm most impressed by the way the large snow overlaps and interacts with the stones.  Great job!

I agree it that really really cool how you pulled that off. I'm still playing around with thge clip file myself.

The world is round... so you have to use spherical projection.

could you share a screen shot of your node setup?... thanks!!,

Amazing Lucio, great work!
Care to share the tgd or node setup, since we're in the sharing area? ;D
Keep it up (to date), fantastic!

Well,

I used it somehow different - but the main part is due to the embossed-snow-idea (though I just went through the written text)

Just have a look. Thanks again to you, Lucio!

wow, neat. yuor ground texture is really cool.

Impressive work Volker, looks really great :)
Seems you're learning pretty quick. The image looks pretty "complete", all elements are present.

Hi Martin,
thanks for the flowers. The image shows yesterday's state of art ,-)

Today, I remodified almost anything. Changed terrain-appearance, colours of the shaders, added fog (for foreground depth), refined the displacements and so on ,-)
The same procedure as the last days. When almost finished I am getting unsatisfied :-)

The image is just a hint that the 'embossed feature' can be used not only for snow  ;D ;D ;D

Regards,
Volker

I understand, and I don't want to sound arrogant but I already thought about using it for sand etc. as well... And like I said you worked that out pretty well :)
However it's one of the best, may be even the best, way(s) to create realistic convincing snow.

I'm curious about your "update" on this one.
Funny to hear you're getting unsatisfied when being almost finished with your image :) Sounds very recognizable! ;D
