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

I believe the viewers add some randomness to the blending functions used to
blend the terrain textures; therefore its highly unlikely that 2 viewers
will see the same results regardless of the underlying OS or platform. In
fact you will likely see different results with the same viewer on the same
machine across different login sessions.
All of the blending occurs on the viewer and there is no way for the server
to enforce any particular interpretation of the terrain settings by any
viewer. If you find that having a grass texture in the 3rd box produces a
more appealing result when viewed with your setup, bear in mind that others
will likely see it quite differently. This is really a deficiency in the
design of the basic terrain system. If you want something more consistent
or better in some other way, you might consider using a mesh (or multiple
meshes) for your terrain.
