SUN-38 is a bug report in the Second Life™ JIRA. The details of the JIRA item are visible to most SL users, I think. In case not, the title is: As users of kneel/lay/sit animations and tiny/giant avatars, we need a way to change the body size in SSB sims.
The description of the problem is:
In server-side baking regions, it becomes impossible to change your avatar’s apparent size (bounding box X and Y sizes and pelvis to feet length) since the LLAgent::sendAgentSetAppearance() function becomes a NOP.
All TPVs are providing a way to adjust your apparent avatar body size: this is of uttermost importance to adjust the height above the ground for sitting (on ground), kneeling, crouching and laying anims (since those specific anims are sensitive to the pelvis to feet length and changing your shape or shoes affects this length, that, when different from the length the animation was designed for, makes your avatar either float or sink into the ground).
RLV enabled TPVs even provide a way for scripts to adjust automatically this “Z offset” so that any avatar sees the animations played right (see the full story about this feature here: http://sldev.free.fr/forum/viewtopic.php?f=7&t=447).
Such a “Z offset” also allows to adjust your avatar’s position for devices you “sit on” and that play a sit animation without letting you adjust its offset (which, again, depends on what shape and shoes your avatar is wearing).
With the appearance of rigged meshes and the tiny or giant avatars, it also became very important to adjust the bounding box (X and Y sizes) for the avatars: a tiny avatar should not bump into obstacles like if its shoulders would be 45cm wide when they are only 15cm, and giant avatars should also have a possibility for their actual shoulder width to be taken into account. Granted, the current (non-SSB) servers do clamp the values sent by the viewers, but at least, there is some possible leeway (and it would be a good occasion to remove that clamping, or at least to allow for a wider range of values).
Being unable to adjust our avatar body size in SSB regions is a MAJOR regression. Please, provide a way to do it !!!
If you only use the SL Viewer, you may not know about the Z-Offset. But, you have seen the reason for it with shoes. When one puts on various shoes they may appear to float above or sink into the floor/ground. This floating/sinking is caused by a combination of how the shoes fit and the size of your avatar.
