Hi Annabelle,

the region interface and the estate tools aren’t all that useful to begin with, and when you’ve got access to the server side of your OpenSim installation, the console commands or database editing work much better and more reliable than any inworld tool. It takes a little getting used to it, but when you get the hang of things, it’s easy.

Personally, I only use the estate tools to change terrain textures (because finding and replacing the UUID in the db can be a bit complicated).

Yeah! that got it ;-) So the region interface is not geared for mega regions?
Thanks so much for your help!

Hi,

I forgot to ask: How do you try to upload the terrain? Via the Estate tool in the viewer, or via command line in OpenSim? If you haven’t already done so, try the terrain-load command like this:

1.: Change to the region you want to change the terrain by typing: change region XYZ (where XYZ is the name of the region)
2.: Load the terrain by typing: terrain load ./xyz.raw (xyz.raw is the name of the .raw file of the terrain). Make sure the path is right. ./xyz.raw assumes the raw file is in the /bin folder of OpenSim. If it’s in a subfolder or an entirely different folder on your computer, the path might be a little more complicated.
3.: You should see the terrain loading inworld, when you’re on or next to the according region.

Greetings

Hi V,
that workaround didn’t work, it still kept loading in the SW corner ;-( ..I will keep trying and let you know if I have any success with another procedure- thanks for your help. A

Hi Annabelle,

I don’t use megaregions because they’re producing more issues than they solve at the moment. What you describe is a “feature” that has its own Mantis for more than a year now. The only workaround I can think of is as follows:

1.: Disable megaregions by setting CombineContiguousRegions=false, either in your opensim.ini or in the divapreferences.ini in the config-include subfolder (if your sim on a stick is based on a Diva Distro; it sounds like it is). Restart opensim.
2.: Upload the terrain files as described above.
3.: Enable megaregions again (if desired) by setting CombineContiguousRegions=true; restart opensim again.

Good luck.

Hi V-
Thanks for this great tutorial. I was wondering if you could advise about a problem I am having with a 4 sim mega region I have made on a usb stick. In my efforts to enlarge the height map from single region to a mega region, I have increased the resolution to 514 by 514 as advised, and made the .raw maps as advised in Baliwick. What happens is that the 4 maps all keep loading into the same region. Even if I am on the SE, the raw file I am loading will load onto the
SW region. I set this mega region up with this tutorial- http://vw-standards.wikispaces.com/Research+-+USB+OpenSim
I thought it was a good, well presented tutorial, but not sure why
your mapping will not work. I also tried your mega region desert
collection, and that would only change the southwest corner as well.

is there a naming issue that is happening when these sims are set up, or is the problem with the maps?
Many thanks for any and all help!
Best-
A

Stumbled across you blog – great article this

OpenSim already has some native support for terragen files but it has been borked for the longest time – seems no one cares about terragen – L3DT gets all the love when it comes to OpenSim terrain generation

there is a patch however http://opensimulator.org/mantis/print_bug_page.php?bug_id=1564 that’ll allow you to import your megaregion terragen files directly into OS.

This will allow the load-tile console command to splat a single .ter file across a megaregion for you – handles the rotation issues as well
