[Opensim-users] PC vs Mac OS Viewer Issue (with a Solution)

[Mister Blue]

I have created terrain meshes using Blender and various manipulations.

A very good tutorial for creating terrain meshes in Blender is
http://www.youtube.com/watch?v=g2EMquDN7qQ which goes through the steps of
sculpting and painting a new terrain. Blender also has a mesh deformation
based on an image so it is easy to do a heightmap or pre-existing RAW file
import.

If you are making a mesh for a whole region (256x256 meters), one "trick"
is to create a mesh that is 256x256 in vertices but is only 64x64 blender
units. The viewers only allow importing meshes smaller than 64m in any
dimension so you must create your terrain mesh no larger than that. But
OpenSim has a console command for resizing objects. So, you create your
terrain mesh 64x64 blender units (which become one OpenSim size unit which
is one meter), import the mesh, and then, on your region's console, do a
"edit scale theObjectsName 256 256 properScaleForZ" where "properScaleForZ"
is the Z size noted at import time times 4.
