[Opensim-users] More 0.6.7 ... Re: Multiple regions using 0.6.7

Fri Oct 16 19:42:47 UTC 2009

I think it is fair to say that 64bit support is still suffering from ODE and openjpeg issues. Most that are using OpenSim are going out of their way to use 32bit OS in both Windows and Linux.

Certainly, 64bit will be the future some time, but those working with it need to accept that they are blazing the trail a bit.

  I am running 64 bit linux at work and had exactly the same two 
problems that
you did.  The avatar problem was resolved with the default settings plus 
changing
av_capsule_tilted = false. There was no other solution that worked - the 
avatar's
legs were bent otherwise, or the avatar mesh intersected with the 
terrain mesh. There
is still the occasional flailing of the avatar, which is something I 
wish we could get rid
of, but we are just living with that: 
http://www.cise.ufl.edu/~fishwick/swimming.png --
seems to be an in-between state where the avatar is neither flying nor 
upright.

  As far as the textures, yes, there is something odd going on but a 
recent fix was made to
transition to a library CSJ2K in 0.6.8.  You'll need to download the 
bleeding edge
version, though, to take advantage of this. I am not sure if the 
releases cover the
CSJ2K fix. You'll also see a huge # of warnings from CSJ2K in the 
console (more
than before with the older decoding approach), however, the 
client-server interaction
regarding texture retrievals is much better. I am not sure if the new 
library solves
all texture issues. There are one or two that never seem to fully 
resolve regardless
of camera-focus/zooming or time waiting.  Make sure to "clear cache" in
the viewer before launching.

  Regarding region crossings, I have not had any issues, though. I am 
using Standalone
with a 2x2 set of regions.
