Original report by Anwenn Resident. Unrigged objects attached to the Avatar Center attachment point, appear to render both mirrored in one axis, and then rotated in another. Looking at Anwenn's screenshot, (I've seen her avatar before).. that's definitely flipped left to right (-1 Y), then rotated 270° (-90° or 4.71239rad) on the X axis. The avatar appears to be symmetrical at a glance, but the backpack is not. There is an orange tube running the length of the right-hand side of the backpack. In the mobile images, the tube is on her left side. I've replicated this effect on another account, with another object, created entirely from primitives. It is not possible through simple rotation, to replicate the shape of the objects as they rendered in the mobile viewer. Mobile users see all attachments on Avatar Center, as flipped and rotated, even when worn on other avatars, not just their own.
