I needed to edit a terrain file for one of my regions in OpenSim. Trying to smooth the terrain with the terrain editing tools in viewers just was not working. Whether one is targeting OpenSim or Second Life it is the same process. Photoshop is where the challenge is, getting a terrain.raw or terrain.r32 file open in Photoshop. This article shares the information I found and avoids a lot of the link rot that has set in on this subject.
Terrain and Camera
When searching Google one quickly realizes there is more than one type of RAW file. RAW files are used for images files created by many scientific applications… and especially digital cameras. When searching for terrain tutorials on Google use the negative term –camera (minus sign/dash and a word) to exclude information about camera raw files.
