Re: Opensim-users Digest, Vol 4, Issue 11

Gurcharan Khanna
hi,

i am new to opensim and new to trying to set up a sim; i only have user
experience with sims up to this point. i have one question to start with
about the structure of a sim.

i notice the basic texture maps for a terrain is 256x256. i assume that
is in pixels. i notice also that the size of a region is usually
256x256. that apparently is not in pixels. my question is what is the
'unit' of size for a region? or what is the relation between the texture
map and the region size? is there an optimum ratio? can one make the
texture map as large as one wants to increase the level of detail?
(aside from performance issues).

thanks for any insight or pointers to documentation.

Hi Guruchan.  This size is in meters.  The size of the terrain height map is fixed - higher resolutions are not possible
at this time.

The units in OpenSim are generally interpreted as meters, so a normal region would be 256x256 meters. Terrain textures can be any size that can be uploaded, typically they range anywhere from 4x4 to 2048x2048 pixels and both dimensions must be a power of 2. There are 4 textures for a given region terrain and regardless of size they will repeat every 7 meters or so (I can't remember the exact repeat number). They also blend according to height and some random noise.
