I'm pretty sure a tutorial walk through will be up at some point on but I thought I would share with you what I know in the meantime. The range of values should be something like. 2 You can play around with this setting but generally. After you have executed the first command, execute: terrain multiply. If you are in world and doing this, make sure you fly well above the terrain, otherwise if you are in the way of a mountain, it will just swallow you up and you will have to regenerate. Make sure the raw file is located in your bin directory otherwise OpenSim can't see it. Name the file and save it.Р”Р‡rom within OpenSim's server console, type the command: terrain load-tile f32 myfile.raw 7 1000 This is important - you'll get a blob if you don't or it just won't work at all. Set the file type to RAW, click the Options button and change the last setting in the list (can't remember the name of it) to float(metres). Choose the Heightfield map, this is all you need to export. When exporting the map, go to File: Export Map. But unfortunately when the map is loaded into OpenSim, the mountains are severe, so try experimenting with this and use a lower altitude setting than you might at first consider. When you create your map in РµвЂ¦С“DT, it is tempting to go nuts with the mountains, which I did. In my case, I am creating a map that should cover a 3 sim by 3 sim area, so, thanks to nebadon and the folks on the OpenSim IRC channel, I found out that this configuration requires a 12x12 map, which can be configured when you create the new map in РµвЂ¦С“DT. РµвЂ¦С“DT also gives you the ability to randomly generate maps too if you're in a hurry and you don't care what the map looks like. This tutorial will take you through the basic steps of creating a map from scratch, which if you are a creative type, is loads of fun. The best place to get started making maps is here. I'm thinking this may have something to do with my internet connection and less to do with OpenSim. When I load the terrain map while I am in world, alone, it works fine. I did notice however that when I try to load a terrain map while I am in world with a friend, I lose all internet connectivity.

With some trial and error, about 8 hours worth, I am now able to generate a map in РµвЂ¦С“DT and load it into OpenSim without any difficulty. Using РµвЂ¦С“DT I can generate a map that covers all 9 sims. In OpenSim, I have now created 9 regions, or sims, that form a 3x3 configuration. The screen shot at left was taken from within the РµвЂ¦С“DT viewer, which actually lets you fly around the terrain map once it is rendered. The terrain maps can be exported to a raw file format and then loaded into OpenSim.

You may also apply ' terrain rescale ' to fit you expectations.There's a free software program out there called РµвЂ¦С“DT that you can use to generate terrain maps, and this thing rocks my virtual world.

In OpenSim the sea level is 20, therefore you may have to do ' terrain elevate 20'.

Where x1 and y1 are the numbers of H/V tiles (one tile is 256x256 ) and posX/posY correspond to the region at the left-bottom of the terrain. In OpensimР’В : in the console typeР’В : terrain load-tile x1 y1 posX posY

Choose R32 and check Options / InvertY = false.

File / Export / Export map / Heightfield.

Do any tuning if you want ( I did no tuning in this example).

in ' Heightfile import options (2/2)' set 'Horizontal scale' (1 pix = x meters, in our case =1) and choose the Min ( -20 deep sea) /Max altitude.

in ' Import height map (1/2)' browse your to your image file.

in ' Design map' (5/5) lease as is and click 'OK'.

in ' Design map parameters' leave as is (4/5).

scale to '1' and set the width/height to your terrain size ( 256x256 per region, with 4 regions you shall enter 512x512)

File / New project / Designable map (1/5).

Brush your land in your favorite paint tool and save it as a PNG or JPG image ( JPEG image introduces some block artifacts due to the DCT compression method) - For information North is up and South is down.

I use another method to generate terrain thanks to the very valuable РµвЂ¦С“DT software. NOTE: Up to now, I have not succeeded this way. Where correspond to the picture ( BMP, TIF, JPG, PNG). Once in an OpenSim console, type: terrain load Using this software, you can create realistic looking terrains, water bodies, etc., and apply various textures on them. The greylevel correspond to the Height field. РµвЂ¦С“DT or Large 3D Terrain is another free world creator software for Windows.
