Title: Procedural River Maps (RGB Maps) Discussion
Post by: WAS on November 10, 2018, 04:23:16 PM
I've created a simple river setup which can be dropped into scenes without cluttering it up too bad with tons of shaders as it's neatly packaged. It offers extremely flexible controls in a categorized manner, plus the ability to of course customize the node network to any aspect the author would want.

This topic can be used as a sort of place to discuss the setup, for help or what not. In the mean time, enjoy the previews. :P

It should be up on NWDA by tomorrow. Thought I'd reserve a discussion type topic for it in case anyone is confused.

Thanks Jordan...most useful I suspect.

I hope it makes things easier to drop in and configure a river, especially through already displaced areas via simple masks.

Was doing a scene with PRM earlier and came across a lovely seed for the River LX Path that produces a interesting split in the river. Has a nice little splay in the 0,0,0 8km region as well.

Seed: 4635 (No other settings edited from Vanilla PRM)

Since the store is RIP, is there any other way to get ahold of this file?

I've reuploaded it to the Terragen Faceboook Community.

Looks nice and clean, I know where to look if I need the river land :)

Yes, we've known for a long time now the store has been closed. The file is now hosted (currently) on the Terragen Galleries Facebook group: https://www.facebook.com/groups/Terragen.Galleries/permalink/2400770373382305/

Please disregard Sir. I've found it. About to check it out!

I don't suppose this file is still around anywhere is it WAS? Getting yellow color in Classic Erosion river setup. 😌

This was a NWDA release. We are no longer hosting the shop. In light of that, here is the quick-drop TGC.

If you're looking Kevin, Crisb, or Matt; could you add the TGC to the main post so it is easy to find?

And I see I didn't get lucky by posting my "disregard" post before I wasted your time. Thanks for the re-upload. Come to find out, if I read through the posts, I can read the answer to where it might be. 😀 without asking questions that have been answered already.

It would appear all your hard work and awesomeness has fallen on a mind to dense to grasp the setup. I generally know when Something is going to go over my head. I did not get that vibe on this. I assumed I would use valley, banks and river maps as masks for displacement and veg etc. and be on my way to a meandering river. I've accomplished nothing thus far. Should I happen to grow a brain I will post results. Thanks again.

I hope you read the documentation thingy? Really comes down to just adding seeds to the warping PFs for something new, and the default maps can be used right out of door.

Very True. It's now working as I originally thought it should work, original issue was a complete user error. With that said.. I do believe I have over-complicated the different displacement setups. I believe their is most likely a more simplified approach that also speeds up the scene. Anyone care to peak at this and prove my theory is correct? :)

Honestly not sure why it's so slow. Strange. Doesn't seem like I'd get much use out of this on my old 4 core, and that's what I made this on. Not sure what's up there. It's a very simple setup, and I made tons of river stuff with it in the past.

I know your order could probably be reversed. Start with valley, than banks, than river displacement. Valley map could probably be used here to just mask out the terrain shader.

Well I'm relieved that the only thing I got wrong was the order. I was thinking your reply would hold gross amount more. Thanks for the advice on order, I will definitely give it a shot.

Indeed hard to imagine having the patience on 4 cores. Though I have looked back on some early renders with crap computers with low spec hardware and wonder where the patience came from. I doubt this to be true in your case though. I'm off to change the order of the maps. Thanks again WAS!

I do know that it is probably prudent to share this was meant to just be a drop-in so I didn't have to re-create the same thing over in over.

The concept of this method is just to start off with a 100% soft huge SSS shape (your valley) and than use colour adjusts (or functions) to clamp in your banks and river maps.  Give me a moment and I'll share a more direct example.

Here is another river scene based on the same concept of the river maps. It renders at 720p with default settings in 1:58 minutes.

Added erosion just for kicks, and also showed how to follow the terrain with water when erosion applied.

Thanks WAS! This will prove to be in invaluable share as after in reordered my maps made little or no difference. 
I will probably learn a more proper way of setting up the displacements as well no doubt. 

Thanks! I'm off to have another go at this.

Well I have my free time filled now. This file answered my questions and provided some new knowledge to explore. For example duplicating the terrain to use as a mask! Never thought about that idea before. Interesting for sure. Thanks!
