Altocumulus R&D

That's very tasty.

Thanks

njeneb, yeah slow computers are OK for final renders while working on something else, but I have no shortage of slow computers...  It's the iterative process of getting to the final render, that's where we all need TG to be faster.

Are the cloud quality samples as low in your large render as they are in the file you uploaded, Matt? Really only 0.25 quality but with no acceleration cache? I rendered it out of the box and it looks very clean, no noise at all. And the rays appear to be multi-coloured too, not just lighter coloured shafts that I usually end up with, these resemble the spectrum. This is great, I love that network for the cloud shapes too, I could never have thought of anything like that. And it looks so simple.
Now we can all see TG used absolutely correctly(), brilliant, cheers!

The cloud samples and atmosphere samples are the same as when I rendered it, but mine was rendered using different render settings in 2.1 so it's difficult to compare directly. I tested it in 2.0 and it seemed reasonably noise free and rendered in a similar time at the same resolution.

Yeah, I think it was cloud quality 0.25. I disabled the acceleration cache because I noticed some problems with it.

nice altocumulus indeed.
and nice to see you rendering something Matt ! ^^

I second that, beautiful clouds

[j meyer]

Yep,nice clouds! And thanks for the files,always good to have some
examples done by the man himself .

thanks Matt!

Thank You Matt!  Just inserted these into my Mt. Rainier scene. I'll post the results if it works out.

looks good..

hope to test on my rig soon.

thanks Matt

OT, if you want to examine e.g. the output from the Colour adjust shader in Matts cloud layer:
Creat a displacement shader, connect the output from the from the adjust shader to input 2 of the
displacement shader. Double click the displacement shader. Right click and select "Open in new window"
If you place the mouse in the new view, you can directly reads the numerical output from the adjust shader
as y value in the view.

With regard to low samples, I've noticed this in a couple of the NWDA packs - it seems to be something you can get away with with thin cloud layers.

Correct, the thinner the cloud layer, generally the lower the samples needed for good quality.

Matt, thank you for the files; but, how do you reseed the cloud pattern?

[Matt]

Create a Constant Scalar function and connect it to the "seed" input of the perlin 3d function. You can then enter any whole-number value in the Constant Scalar function.
