[Opensim-dev] Ruth vs Gas Clouds: Bug or feature?

[Melanie]

I believe I can explain this.

JCool, the creator of the Emerald Viewer, has been able to shed some 
light on this, since his viewer has been using a similar feature 
from the start.

Bots largely depend on viewer compositing, this means they send the 
individual clothing layers, but no baked ones, and the viewing 
user's viewer composites them into a viewable avatar.

Starting from 1.23, LL viewer no longer send, or expect, compositing 
layers. Avatars no longer carry texture information about their 
individual clothing items. This is to combat theft, avatars now 
carry only the 3 baked textures. Therefore, Copybot can no longer 
rip clothing from an avatar it sees.

Because of this, the "Cloud" stage is perceived to be longer on 1.23 
users, as they don't render until the bakes have been pushed to the 
server and then downloaded by the other clients. An avatar counts as 
unloaded if it's visual params are the default ones OR it has no 
baked textures. Previously, it would count as unloaded only if it 
had no textures at all, or all default visual params.

Since bots don't bake, they will never render for users of the 1.23, 
since it neither creates not expects compositing layers.

Conversely, users of the Emerald Viewer, which features clothing 
protection, appear as light grey avatars until the baked textures 
are pushed to the server.
