Cirrus sunrise
« on: November 10, 2017, 10:35:15 AM »
Trying to replicate a phenomenon.
Screenshot of node network.
Thanks for the hint on the setup Dune. I got this far but I am missing something, as I do not get the curves in shader preview like in the simple road setup. (Yes, I see the similarity) ;D

Dune, why do my curves not transfer?

You need to use a Get Position In Texture instead of the Get Position node. The latter works on final render position, the former allows you to distort the position call.

Also, I just noticed, you should try and plug your Sin Scaler 01 into the input of your Warp Input Shader 01 and bypass the Transform Merge Shader 01, that will allow your vector displacement to warp the Sin function set.

Thanks Hetzen! I tried that w/o the transform merge and voila! I got some very cool patterns that I want to try elsewhere, especially with a low scalar on the sin side. Psychedelic fractals!
WIP I will add some more vegetation to pick up the highlights.

These clouds are awesome.  Glad you guys got it figured out.  Way too complicated for me.

Thank you!
My profile picture is done with an image map mask.....I can make a trillion of those a day, but this node stuff is fun too!

Awesome, glad you got it working and looking good. I agree, it is fun working with these blues, especially when creating abstract stuff.

You can do all sorts of things with that network. You can get the negative values of a sine curve to be always positive by adding an Abs(olute) Scaler after the Sin node, that will give you constant bumps. A bit like Perlin to Perlin Billows.

You can also Add to the 'X to Scaler' node another PF, distorting the position input, which will 'warp' the sine pattern in a similar way you've used the Warp shader for the above. I'd put a Multiply Scaler in after the PF to make the position distortion more than 1 meter if you did decide to try that.

Lady of the Lake.
It doesn't have to be complicated using blue nodes. You can simply mix two PFs just by putting them both into an Add Scaler node for example. Or get marble like patterns by swapping out the Add with a Difference Scaler. You don't need to know math to do that. Try a few simple things out. The node preview window inside each node, is useful to see how your pattern is changing through the network, and before you know it you've made a great texture.

Yes, I think a lot of people are a bit too 'afraid' of blues and don't touch them by principle. They're very handy as an addition.
