[Opensim-users] Mucking around with IAR asset UUIDs outside OpenSim: Will anything bad happen?

[James Hughes]

Hi Edmund,

Thanks for your work on Sloodle. I loaded an IAR with the new system a 
couple of weeks ago to check it out and I ran into something similar. I 
resorted to diving into the IAR and trying to fix it. But, didn't get 
too far. I have been meaning to ask Justin about it, but have been 
pretty scattered lately. Hopefully he can give some insight - and 
hopefully I can have a little time to check these out again and offer 
some feedback. The last time I tried, I wasn't able to get all the parts 
to work, possibly for the reasons you are discussing.

Thanks
