What programs can I use to create terrains for OpenSim?
If you are after simple terrain files (jpg, gif, etc), you can use Photoshop or any number of freeware programs, like Gimp. If you want more complex terrains, you will need programs that output to standard 3d raw format (aka r32 or r64). L3DT and Terragen are two of the top commercial programs for this. (anyone know of a freeware one?), or you could, with some practice, use Blender. The free version of L3DT can make terrains up to 2048×2048 in size, or 8×8 regions. You can use `terrain load IMG yourfile.png` to load greyscale PNG files. Remember to use something like `terrain rescale 0 25` to make it visible.
