That's a really nice subtle effect Martin. Thanks for sharing. It will be good to see the difference with the less warp at feature.

I'd also like to have a play with this effect on a planetry scale to see if you can get a gas giant timelapse effect??

Cheers

Nice test Martin. Makes me want to try this kind of effect

Very cool. This interests me a lot martin, good job as usual! Perhaps you will get so good with animating clouds that it will become very easy for you to explain things to simpletons like me. I read your tut on animating clouds, but it was over my head at the time, perhaps I should revisit it.

Thanks, folks.

Badger, I don't think I've ever made a cloud tutorial, or really any tutorial, I made a grass surface and I think an old crappy fake caustics one a few years ago, which I wouldn't even advise anyone to look at these days, and I think that's the only actual 'tutorials' I wrote.
I usually just find a cool thing/s, post some files and explain how I've done it for the benefit of anyone who cares to read it or, I'll just share what I 'think' I know about things in places like this.
Maybe you're confusing Martins? We are many in these parts!

Has TU maybe made a cloud animation tutorial, I know he did a cloud function one a while back.
If I have, I've forgotten about it now so, it probably wasn't up to much in the first place! I don't think I have, though.

The above doesn't get much easier to explain, though. Point your camera to the sky, add a cloud layer, keyframe the 'warp amount' on the first and last frames, hit render sequence.

"cloud function one "

thats the one. Apologies.

I've got v2 done now, with 'less warp...' disabled.
Just the same warp settings otherwise.

Next I'm going to significantly raise the warping to show the broiling effects you can get with the density warping, the link in the first post shows an early tester where I used much more warp, that should look good at higher quality and resolution. Think I'll just do 10 seconds this time, instead of 30, update later...

Cheers!

* And here's one that I did before any of the other ones on this page. I didn't post it first because it's much more subtle and you can't really see what's going on as well as you can in the newer ones. Might as well stick it up here now that the other two are done, though.

I hope it's just because of the slight drop in cloud samples and smaller resolution that the lighting is broken on this one, none of the other tests have had this flickering, it's the same cloud. #video deleted link removed#

I've reverted back to the original detail and render settings and I'll run it again to see if that flickering goes away.

dandelO · February 16, 2012, 03:09:37 PM

I think it's actually just the acceleration cache, it's set to optimal. The flickering is still there but not as bad as the last tester. A full scene render might be on the cards with nice render settings soon...

Bit of a fail as I buggered up the keying on this one when I shortened the length, doh!. The warp is also way too much but it shows a nice rolling kind of motion near the start can be made, if it was controlled a bit better.

really promising and convincing effect...
ingenious!

dandelO · February 20, 2012, 09:54:55 PM

There are 5 different 30 second warps in this video. http://www.youtube.com/watch?v=ZLBelniBuso

Nice ones Martin. I liked especially the 2nd and 3rd clip.

yossam · February 20, 2012, 10:33:33 PM

These are great.......I like the last one.

Dune · February 21, 2012, 03:37:16 AM

Awfully nice and realistic, Martin! Did you use any other input in the cloud node or just the warped cloud fractal? Reason; if you feed the other inputs with animated warp you might get some dramatic results. Yeah!

dandelO · February 21, 2012, 10:13:09 AM

Hi, Ulco. I did do some messing around with the same thing into the other inputs, the depth and final density inputs make nice results(especially the depth) but the fastest to render is just plugging straight into the density shader port.

Thanks, all!
