True Invisibility on a prim or prims

I read a post a few weeks ago which included and talked about an invisibility script, which when run, makes the prim invisible but also you couldnt see anything behind it.

So if you stood behind the prim, you couldnt be seen. So its not an alpha texture.

Anyone have that script?

Ive trawled the forums but mosts results are giving me alpha related posts

It's (probably) the script in those transparent prims that make your foot invisible in high heeled shoes or similar. It won't make you truly invisible because it will affect the environment too - and other stuff - might be fun to play with though...

Search the scripting forum for the word "invisiprim". You'll find tons of examples of the script.

Just so you know, it's not that you can't see ANYTHING behind it. It just hides certain things. Namely, it hides avatars, any surfaces with 32-bit textures, and optionally, shiny surfaces. 24-bit surfaces are always visible.

Or you could leave the prim out of the equation all together, get rid of the distortion on the environment, and still be invisible using an animation that throws your av into the ground.

Probably better to go for the mulyiple invisibility prim trick for the "Predator" look

And avoid anywhere with a second floor or a sewer system or basement.

It's for hiding a friends skybox lol (well it's a holodeck to be accurate!)

So if i cover the holodeck with 32-bit textures OR apply slight transparency, it will be hidden inside the invisiprim?
(Assuming that the holodeck has some sort of mod permissions on the shell...which i doubt)

And what about items that are in the holodeck? (platform, controls etc)

Think I'm gonna have to expirement!

Thanks for the feedback/replies

No, the invisibility prim will not do that. It'll distort some colorations in the environment and completely remove the avatar mesh (not prim avatar parts though) and that's it. If you use a fully transparent texture on the outside of the deck, it'll show the contents and any opaque walls on the opposite side (interior walls in the sight line). Put the skybox above 350 and it won't show on the map. But anyone with a flight assist will be able to find it, regardless of your texturing. Even if you had it the exact shade of the sky surrounding it, all they have to do is switch the time of day and it'd show up very visable.

You'll still end up seeing anything that has 24-bit textures. Which likely means any "naughty bits", prim clothes, prim hair, and a whole lot of other things remain quite visible.

In short, you'e trying to do soemthing that just won't work. It's been tried over and over.

There is only one effective Privacy in SL. Buy a private sim, take the whole sim off the map by unchecking "Public Acess" in the estate tools, and restrict access to the sim to only invited guests who join your land access group. Then only you and your guests can see what happens in that sim. Anything else is trivial to circumvent.

I was playing with invisiprims when windlight was only on the RC viewer and it hid regular 24 bit textured prims (non transparent) from certain distances. I covered my work platform with a mega invisiprim sphere and it made the whole platform disappear. You could see the sphere shape if you were above looking down into the ocean but you could not see it from below or from the side. Invisiprims no longer remove shiny on prim surfaces too.



Well I just tested it on the main viewer and it looks like they did change it back to normal. Looks like it doesn't hide all prims now. I suppose that would break a lot of avatars if it did. At least shiny still works.

I have been able to get some true invisibility by surrounding my stuff with an invisibility prim, and putting a slight transparency on my stuff, even 1 works (texture tab, alpha 1). Likewise, making sure whatever prim stuff I am wearing also has a transparency of 1, its not enough to effect the general look outside the invisiprim, but it is enough to be able to hide behind the invisprim pretty well. Not that I have a habit of hiding or anything...just stuff I have been playing with.

I would like to take a note here that the engine considers invisiprims as fully solid, even if we can see through them and therefore object occlusion culling could cause even solid objects to disappear.

Yeah, Nexii makes a valuable point: the invisibility textures are simply textures that the system treats in the manner of an opaque texture, yet are see-through, and consequentially it will cull out even opaque objects behind it, so long as it does well to completely obscure the entire OBJECT (not just texture or even prim). (This explains Bree Griffin's confusion about something that seems to have changed but really didn't.)

Therefore, if all you want is a room in the sky that doesn't affect the view of the sky, these invisible walls should do the trick, just so long as they're about... *tests...* twice as big as the room? (Note that the sky and the terrain are pretty much the ONLY things they won't affect.) Sounds like time for some invisible megaprims.

Culling does seem to explain what I recall seeing as the avatar always remained invisible while the prims would disappear or reappear based on my camera view.
