That might be it - it was something with replication of the nodes across the network, so you're probably right.

Ah, well these experiments have thus far been strictly single player, so I could totally have that crash waiting for me as soon as I try to network it. Looks like a good thing to try...

Hey @

is there a good place I should go to find heightmap data for real-world locations? I've been thinking I'd really like to recreate some real terrains... I'm not too concerned about doing the whole streaming terrain thing - if I could just find a way to get a black/white heightmap image that'd be awesome.

Well, if you were in the US or interested in US locations, the answer is emphatically yes:

http://nationalmap.gov/viewer.html

For Australia or Europe, or other parts of the world, I'm sure there are sources but I'm not sure where they are... however a little looking around reveals that you can find SRTM data at (I think) 30 meter resolution here:

http://eros.usgs.gov/

There might be better data somewhere - for the US data in my first link you can get it down to 10 meter resolution, I'm not sure what is the best available in the rest of the world. You could also ask around on forum.flightgear.org for sources, a lot of those guys are based outside of the US.

You also might potentially want to take a look at my original "T3DTerrainMaster" project on github,

http://github.com/ChrisCalef/T3DTerrainMaster

just for ideas on how to import the height data, although I'm sure you can figure that out easily enough on your own.

Good luck, let me know how it goes!

Thanks for the tip, I'll see what I can find. When I saw that first link I was like 'whoah America has a national map, too?' Here's Australia's :D I also found this, which relies on Bing Maps' API.

Another tip: if you don't already have it, grab 3DEM from here:

http://www.visualizationsoftware.com/3dem

It's an extremely useful tool for converting from SRTM and several other height data formats into .raw or image files. With it you can combine multiple height data files into one and then save them all in a format more useful to your final application.
