The previous part of this tutorial is OpenSim Terrain Tutorial via Blender – Part 1. The previous part is about getting terrain from Second Life and OpenSim into Blender. This part is about exporting the terrain from Blender 2.59 as a height map image.
Height Maps via Blender Nodes
By the time you start this tutorial you should have a completed terrain or at least have a test terrain to try.
Also, you should have a backup of your region. Loading the tutorial can mess up your region. So, a backup is a good idea. In OpenSim I make OAR file backups. (save oar [filename.oar] – save to OpenSim’s working folder. You can specify a path.)
Now is a good time to back up your Blender file too. It is a great idea to work in a copy of the file.
Updates: Includes minor updates for use with Blender 2.63.
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 into Blender and Part 2 about getting terrain out.
Terrain Imported from OpenSim
I’ll be working with Blender 2.59 and OpenSim 0.7.2 Dev. The height maps can be used in either SL or OpenSim.
Terrain Vertices Count
First I need to know what I’ll need to export for use in OpenSim. Plus I have a terrain in OpenSim (OSGrid) which I’ve worked on for some time that I want to get into Blender and start from there. So, I need to import and export terrain to and from Blender.
