Bug Reports and Help / Problem Importing .tif generat...
Last post by rogue24 - March 29, 2019, 11:43:36 am
Hello,
I am new to World Machine and I am having trouble importing a DEM in .tiff raster format generated from Agisoft Metashape.
I want to import the DEM and edit it in World Engine.

When I import the .tif DEM, no terrain is displayed, only a while block (maybe max value?)
Any suggestions would be helpful.


Thank you,
Tony

Bug Reports and Help / Bug: River reaches with trapez...
Last post by mattnava - March 29, 2019, 11:38:40 am
It seems that if a river reach is using the trapezoidal channel type, it will not contribute any data to the flow map(making a totally still river), even when flow speed is specified manually and set to 1. Changing the reach to use the curved channel type makes the river generate flow data. The expected behavior is that either channel type should generate flow data.

Thanks for the clarification. Heres hoping for support of distributary connections at some point in the future!

Hi Stephen,

thanks for replying, I am looking to include them into the terrain as some part of the geo and the height map, we have shots where the trees would be miles away from the camera.

I was able to get it to show as spikes on the terrain that looks OK, but I was wondering if there was a more refined way of displaying them.

Hi Matt,

Just to copy our helpdesk conversation here for others' use:

When you connect a child river to a parent, the child river is forced to flow into the parent as a tributary. This is usually what you want; a tributary flows into its parent. Since that relationship is forced, the option to flip the river direction is removed.

While the opposite sometimes does exist in real life (so called 'distributaries'), it is relatively rare and occurs mostly near river deltas, etc, where flow splits apart. The manual river system supports only tributaries at present.

Hi there,

Are you looking to "simulate" trees in World Machine by including them into the terrain or texture created from WM, or drive vegetation in your renderer with a weight map?

For the first, there is a macro included with recent World Machine builds called "Vegetation Scatter" that will do what you want; feed it your existing texture and a weightmap governing how to distribute the vegetation.

For the second, the latest build 3025 'Alpine Lakes' includes a Select Wetness device that is great for plant placement as it produces an index of soil wetness; otherwise, try using the erosion flowmap output for a similar effect.

In XCOM, characters move from square tile to tile. As result, terrain must be aligned to the square tiles. Any idea how do a map, where terrain is aligned to these tiles? So it never happens that slope goes through a square tile intended for movement?

Hmmm. It seems like its only supported to connect rivers coming from upstream, not splitting rivers downstream. That seems like a somewhat arbitrary limitation... Is that by design for some reason? Can we get the ability to do either? That would enhance the direct-ability of these rivers greatly.

Hey, Im trying to draw some branching rivers using the river node. When I snap a river to another, I noticed that the option to switch the upstream end of the stream disappears from the right click menu. Unfortunately, the direction of the river also changes to face the incorrect way sometimes. Seems like a bug! Am I missing something? is there any documentation about how drawing these rivers is supposed to work? thanks!

I attached an image showing the issue. the lower long river was snapped to the upper long river and its direction reversed. its no longer switchable.

Im using the latest dev channel release 3025 Alpine Lakes.

hi everyone

Huge fans of world machine and been using it on many projects, and we are working on a movie that has these aerial shots of some mountains, .

I am trying to work out a way of maybe scattering very small trees.

there was a previous post here with someone that was able to nail that look, and I wondered if you guys can suggest ways of creating the same exact look?

any help and feedback would be greatly appreciated
