Blender 2.5 has a new import feature that can be used for making terrain in Blender. Most terrain tutorials are about getting terrain into Blender and little if anything about getting it out. Those that are about exporting terrain are mostly for Blender 2.49. There are enough changes between 2.49 and 2.59 that it is hard to figure how to accomplish 2.49 tasks in 2.59. This article is about importing terrain to Blender and exporting for use in Second Life and OpenSim. Part 1 is about getting terrain in and Part 2 about getting terrain out.
