As an avatar builder, we are quite dependent on hiding the default 'human' avatar on our builds by using invisiprims. They're clunky, they're ugly, they get in the way, and they're easily seen through anything with an alpha channel texture. We would not need to use invisiprims if we could make the avatars transparent through the skin or clothing layers. I would love for LL to give us the ability to make the whole avatar invisible through regular transparent textures. If that is not doable, could they at least allow us to have "Invisible gloves" and "Invisible boots" that would cover up the avatar's skin? (As many of us have to use invisiprims to cover the hands and legs, this would be a good compromise.)
