The coming Quick Graphics Viewer now in RC has some odd behaviors. Well, it is an RC version, so no surprise. One of the ideas with this viewer is to reduce render lag by telling the viewer to avoid rendering complex avatars. These are avatars with lots of high polygon count attachments and large textures that require lots of computer power to render.

There is a setting in Preferences* that lets you set a personal limit for what you want your viewer to render. Any avatar over that limit will render as a jelly baby. But, if you change the setting to NO LIMIT you’ll find there are still avatars that render as jelly babies. What’s up with that?
