This is a pair of resizable and tintable round sculpted prims that painted in black and with some level of transparency they give the effect of progressive darkness. So when these prims are set to be phantom, avatars can walk into them, like walking into darkness and then keep on walking and they will progressively come into the light again.
Main applicacion for this kind of effect are for tunnels, pits, cave entrances, corridors and even to simulate dense water on swimming pools when u give it a tint of blue, or red of u want to fill your pool with blood.
The difference between the included prims are that one of them has double the progressive density making a finer effect.
Play with the level of transparency and the length of the prim to adjust the progressive effect to your needs.
Also available as square progressive prims. See related items below.
