Region Crossings

There have been reports of worsening in vehicular region crossings recently (by coincidence, Caitlyn and I ran into so particularly unpleasant crossings over the most recent weekend). Simon Linden agreed to have a poke at server logs, time permitting, to see if there is any other change in crossing stats. He also mused on the potential impact of mesh bodies and attachments on such crossings, which constitute a considerable amount of additional data (including saving and restoring the state of scripts associated with them.

It was also pointed out that worn mesh attachments bring with them an (unneeded?) physics shape calculation, potentially adding to the load. This prompted a further discussion on whether any attachments should have a physics shape data used or calculated until such time as it is physically rezzed in-world.

As a first point of call, Simon repeated that as time permits, he’ll look into what goes into the region crossing calculations, and have a closer look at attachments physics calculations in general to she what is going on.

What Is the Lab Working On?

Things seem pretty quiet at the moment, but the Lab is working on a lot right now, although much of it is transparent to users, as Oz linden indicated at the Simulator User Group meeting on Tuesday, May 2nd:

At the moment, we happen to have a number of projects in flight that are either not good to discuss (security changes), or system upgrades that really shouldn’t be visibly different…. that’s unfortunate, but we’re getting started on (or getting ready to start on) some that will be much more interesting.

The recent changes to land access and control, together with the upcoming changes to allow region / estate staff to better managed Public Access regions are examples of more visible changes affecting users – or will be, once the viewer has been updated to handle the latter; and there a further changes to the likes of region-level ban lists coming down the pipe which will also bring visible changes to the viewer and provide better controls / support for land owners.
