Invisibe parts and more

Hello everyone!

As far as you know many boots includes invisible parts. I am talking about texture that hides part of avatar. Some time ago I saw sphere with texture wich shows avatar inside it with one color. The question is - is it special textures (may be shaders)? And where can I find complete list of such textures?

Thank you.

Shoes commonly have an invisiprim to render the ugly parts of avatar feet invisible while leaving the shoe intact. You can make one yourself by dropping this in a prim (not including the "

" tags that are for formatting in this forum)....

CODE

default
{
state_entry()
{
llSetTexture("38b86f85-2575-52a9-a531-23108d8da837", ALL_SIDES);
}
}

Thanks, but I've been talking not about invisible parts only. I am interested if there are other types of nonstandard textures. Water for example.

The invisiprim textures are really the only "magic" ones, they're really very ordinary textures and the viewer happens to apply special treatment when it sees those UUIDs. (They are really alpha masks for blending terrains, it was a bug in the blending feature that originally opened up the invisiprim effect).

Here is a simple recipe for the avatar silhouette trick:

1. Make a sphere
2. Hollow it out, 95% will do, you'll want it phantom so you can walk through
3. Temporarily dimple it to make texturing easier, end dimple .5 or so.
4. Get some alpha on both the inside and outside, just select the sphere and set the whole thing to 1% transparency for now.
5. select texture on the inside and tint it some color, leave the outside tinted white for now.
6. At this point you can set the end dimple back to 1
7. And now the magical part: set both the begin and end twist on the sphere to 180 degrees.
8. Walk into the sphere, your avatar will be rendered as the hollow face's texture & tint.


That same twist trick is one of the ways people make "cel shaded" prims. A second way to get the cel shade effect is to use two concentric prims, where the outer prim has a solid inside and a transparent outside.
