Bug Reports and Help / Re: Delete Device Bug?
June 05, 2010, 04:37:34 am
It happens when you have selected the group before deleting the device. I'll add it to the bug tracker.
There are multiple ways to fix this. Here is one of them:

Let H be your heightfield an D the details that you added.

What you did is this:
A = D-H
You get the details/structures that were added by erosion. Values below 0 will be clipped, but...
You can also do it the other way round
B = H-D
in which case you get the details/structures that were subtracted by erosion.
Create a new map with a height of 50%. Let's call this map G. And do the following.
Final result F = G - B + A

Now all you have to do is teach your 3D program to interpret 50% as 0.
Why don't you render it 8k the first time and then downsample/export it using a new WM file?
The resolution dependencies aren't caused by seed values. You're simply getting problems when the output of a device relies heavily on features in the input that only exist in the hi-res version.
Devices that work with high frequencies, derivatives or other small details are particularly affected. Erosion for example is somewhat chaotic, butterfly effect-ish.
I had a similar problem once. It stopped after I first saved a file.
Hm... That's odd.
Two things you could still try:
1. Look into the paths shown in Preferences > Paths
2. As a last resort, use windows' search to search the whole drive for the file/folder.
Have you looked into your Documents folder? And maybe into Appdata etc?

What security verifications? The windows accout control stuff? I believe you can minimize them by setting your paths (those for macros etc) to a place that isn't "C:/Programs".
If that doesn't help, maybe try to run the whole program as administrator (right click > run as admin)?

Personally, I'm running Windows Seven and don't get any notifications at all.

Tmd files are world machine files that you have to open with world machine.
Macros and Plugins / Re: River Bed Macro v0.9

No, it's not.
The macro was made for the free edition which lacked the curves device. This is no longer the case, the curves device exists in all versions of WM and is a much faster tool than the macro was.

Have you checked if it appears blurred in 2D view too?
Do you have any resolutiondependend devices in your network, like Blur or Erosion with scale independent unchecked?

WM2 can do everything, WM1 can - why do you prefer WM1?

Take a look at the sticky topic just above your thread ;)
General Discussion / Re: The Right Tool for the Job?
February 11, 2010, 04:24:48 pm
World Machine is a tool for creating terrains - you will have to do the rest of the 3D stuff in a real 3D program.

But the part about generating the terrain looks feasible :) (except realistic rivers)
WM can export maps as Wavefront Objects (obj) so you can easily use the generated terrain in the 3D package of your choice (TG2 is a relatively cheap landscape renderer but animations are tricky). You can also generate maps at different resolutions for LOD purposes.

I suggest you download the free version and just give it a try! It doesn't have some of the features of the commercial version but will show you what WM can and can't do.
General Discussion / Re: Hills and Mountains

Can you post a screen shot of what you have so far? (any why it's not enough four you)

I think you might have some success with voronoi.

You might also look want to take a look at my voronoi noise macro (http://nkblog.nkdev.de/?page_id=446) which creates terrains that look somewhat/a bit simlar to what I think you want. Screenshot: http://nkblog.nkdev.de/wp-content/uploads/2008/09/wm-voro-slate.jpg
General Discussion / Re: Hills and Mountains

Just generate mountains and hills in separate generators and combine them?
You'll probably want to use a mask to restrict the addition of hills to the valleys and maybe blur the valleys before combining.
1. Sounds like a memory leak.   
(2.) If this is the case, you can't really do anything about it.
3. I don't think so - it's a software error. Also, the next version will have more sophisticated memory management that makes larger builds possible without buying better hardware.

For now, save before using Layout Mode and kill WM via the taskmanager. This is faster than waiting.

edit: I can confirm this and will write a bug report.
Just color them with equidistant grey values.
You can always rescale the height map in wm using the Clamp device in Expand mode.

Maybe it's even possible to create a map form isolines in WM.. but not without a significant amount of trickery.
probably not

But also search the internet! There is probably a free tool out there to convert iso lines to height maps.
Feature Requests / Re: Planetry Data
January 05, 2010, 08:37:18 am
It wasn't a poor explanation.

I guess the main problem is the poles*. For now, it's probably be best to
0. Set the map extents properly (such maps are in a 2 by 1 format [306°x180°])
1. Make the map seamless in both directions, see this thread: http://forum.world-machine.com/index.php?topic=1159.0
2. Motion-blur the poles and maybe apply a little regular. You'll have to try and see how much motion blur works well.
... I think this could work.

*Someone should remove this amiguity from the english language
General Discussion / Re: Erosion - multithreaded?

Erosion is multithreaded.
Have you set the number of worker threads to something >1?
