Bug Reports and Help / Re: SRTM Seafloor
« Last post by kris392001 on September 15, 2018, 10:56:16 PM »
Thanks, that raises the flat seafloor to the level of the coast unless I'm missing something.

What I'm trying to do is a apply a gradient/slope from the coast level (140m) down to the current seafloor (0m) at a distance from the coast (500m?

Perhaps there is something I could do with blur and a mask.

Combine a "constant" with the terrain, set combiner to "max" mode. Then set preview to the combiner, and then raise the constant height until the land is level at the beach. Next you can select this area using a "Height selector" on the original unmodified terrain (use height=0), and the use it as a mask when you combine the previous terrain with your "seafloor" terrain "inverted", use the "subtract" mode in this combiner.

Hi All,

I'm starting to clean up some SRTM data and wondered if anyone had a method or macro for applying a gradient from 0 to the coast (which I managed to raise to 140m in Photoshop - see image). I tried putting a gradient mask around in Photoshop but the results weren't very satisfactory. I'd like to try and get a reasonably realistic seafloor.

Edit: I realise I could erode but I don't want to change the existing land form.


Feature Requests / Disable splash screen when running from script.
« Last post by jshort on September 13, 2018, 07:47:45 AM »
Would it be possible to disable (with a command line flag if not by default perhaps?) the World Machine splash screen when running it from a script? It steals focus, making it hard for me to work on other things whilst exporting from multiple scripts sequentially.
Feature Requests / Vastly speed up interactive preview
« Last post by Foxer on September 11, 2018, 10:22:04 AM »
Man this thing is making some fantastic moves in the last year! Improvements in the UI and pretty much everything....but

The preview is slow while making adjustments. With complex networks you will find that you are making adjustment and wait wait wait for it to flow through the graph and update (although it IS much faster than it used to be).

When adjusting the sliders you are not getting to use all the cores like you do when you are "building" (and I do get why...multi-threading real-time interactions isn't simple). 

This puts you in a situation where you have to constantly build build build to see the output at reasonable resolutions. I wonder if there is a way to speed this up?
Geology and Terrain / Re: What are my output mask options please ?
« Last post by WFab on September 10, 2018, 12:25:03 PM »
All erosion types (natural filters), output some sort of helper mask, besides the processed heightmap. For example, "Erosion" device outputs "flow, wear, and deposition" masks. You can output these using "height output" node. Also, you can use "bias/gain" filter on them to bring out some contrast and brightness, if you desire so.

About the provided example "snow", the snow device outputs a helper mask known as "snow depth mask". You can save that using a "height" output node as well. In your "examples" folder, look for "RGB Examples>(RGB) Snow Device Example".

Hey all,

Having lurked around the forums long enough, I've taken the plunge to register as i need some help please.

I'm trying to make a terrain for use in UE4, I'm only learning so no project in mind, what I can't figure out is how to output good quality masks for my surface materials, all I can manage is to mask by slope or height, what other options are there and how do i use them ?
For example how would i get a mask for this snow ?

I'm ok with using WM2, I can get the results I want, I just can't get my surfaces to output, things like cliffs, snow, grass, cliffs and beaches etc
I'm not looking for a splt map, I was looking to export each mask as a black/white image, so i can assign each surface to an image.

I also suck at image software, even M$ Paint get's the better of me, so no PS here  :?

Many thanks in advance,

Alright then! Have fun with your world, and do share a screen or two when it's done!

Thanks for the offer, Pratyaksh, I appreciate it. Stephen got back to me and the answer turned out to be embarrassingly simple. I had assumed the the Mask Extents output should be used but it turned out I needed to use the Heightfield output on the File Input node.
Bug Reports and Help / How To Make A Terrain Smaller in World Machine
« Last post by MarsMiner on September 07, 2018, 10:01:06 AM »
Hi all,

I am new to both the forums and world machine and am having a problem. I have spent quite a lot of time creating a terrain with layout generators and all sorts. I plan to export it in small chunks by moving the world extents along and re exporting a new area each time (I am using the basic edition so I am doing this to get a slightly higher resolution.) However, I have realised my terrain is massive and it will take me a long time to export it a small area at a time. Is there any way I can scale down all my layout generators and everything so it is easier? I know I will get less overall detail but that doesn't matter. I can't just export it and scale it down in my game engine - the entire idea is I need to make it all smaller in World Machine so I can export at a high resolution in small chunks, but I won't need as many chunks.

Is there any way to do this other than start again and design everything smaller?
