displace cloud by normal

[Dune]

I guess this is not possible.... but it would open a lot of opportunities, like cones (without blue nodes).

Clouds don't use normals. You have to define a volume with them.

Good thoughts Ulco. Tried your suggestions but couldn't get a working chain. Then, the Plane with Painted shader worked; but, the clouds looked more like Casper the Friendly Ghost. Tried different cloud settings but gave up. Maybe a way of 'resizing' a localized cloud mass would work; i.e., shrinking (or expanding) the overall cloud mass size?

There must be a better way of doing this.

Maybe being able to replicate and localize a steam cloud mass like this.

Yeah...that would be very cool...also for train engine steam and chimney smoke

And you "define a volume" by....? or are you referring to the settings we currently use...sometimes definitions confuse me .

Clouds do not use displacement data at all. They use color info to define a shape (volume). Color intensity controls volume density.

Can a cloud be 'driven' by an object to conform to a shape? Or conversely can an object be given a cloud shader?

[Oshyan]

Nope and nope. It would be a cool feature, but not currently possible.

I thought so, about the normals. So it's blue nodes after all.

There was a thread sometime back where a number of 3d shapes where created with clouds using blue nodes but I can't find it,

thanks Oshyan...did not know that,,,,

[Dune]

Yes, there are some blue node combi's about. In fact, I probably seen them all and use a few, whether or not adapted.

mhaze - Here you go,it was within this thread.

Blue nodes or for some easy shapes like a cube you could use SSS projections.
On more than one axis,that is.

that's the one, cheers
