Megaprim 666 x 666 x 666 ?

Just wondering if anyone made a megaprim 666 meters by 666 meters by 666 meters, a size prim which could be nicknamed "the Satanic Majesty", or some such.

Suzanne - I know from reading yr other posts that u know a lot about this kind of thing - so while we r talking about megaprims, would u please tell us newbies what a megaprim is exactly (besides being big) and why we would want one? thanks - Saucy

Certain sizes are useful when you're trying to save prims.
I wouldn't have a use personally for megaprim that is 666x666x666 unless I want to make my own havoc 5 or something.

Sl's prim size limit is 10x10x10
There were some prims created via an exploit where one or more dimensions exceeds this limit.
These are called "megaprims"
They are useful in making larger builds. A 20x20x.5 prim uses 3 fewer prims than using 4 10x10x.5 prims to cover the same space.

would a mega prim that size even rez in a sim or would it be too big?
i mean wouldn't it overstep the sim lines?

Wow, you would need to own 9 sims (3x3) to rez the thing.

I think I need one anyway.

would one rez in a region though i wonder or would it not rez because of sim lines?

the bigest i have rezzed is a 256x256x256 and it ate up the whole sim lol
i was worried it was gonna crash the sim lol
actually rezzed two because the first one rezzed over head

The LL intended limit for prim size has been and still is 10 x 10 x 10. This used to be a good idea for technical reasons related to LL's implementation of Havok 1 as our physics engine and the way the virtual space in SL is simulated by dividing it up into processes which are run on thousands of separate computers. It also reduced the ability of users to make trouble for other users with huge prims, intentionally or accidentally.

The code that checked to see if a prim was larger than 10 x 10 x 10 was in the viewer code, secondlife.exe. This allowed the "notorious griefer" Plastic Duck to create some prims that were larger than 10x10x10 by bypassing that check. Plastic Duck used an account by the name of Gene Replacement to create these older megaprims, so all the old megaprims will show a creator of Gene Replacement.

I believe at some point this check for prim size was added to the code the server runs, so that if you did send a request to create an oversized prim to the server, the server would reject it.

When Havok 4 got implemented, the check was apparently left out or disabled on the server side, thus allowing the oversized prims to be created by those who new how to do it with either a modified but basically normal SL viewer, or a libsecondlife based client, or by manually creating an object creation request packet and injecting it into the stream sent to the LL servers using a program called SLProxy.

The check for prim size at time of creation has been added back to the server code now, so the new round of megaprim creation has come to an end.

Big prims make it much much easier to build big things, that's the primary reason why big prims are nice.

I think big prims may reduce the number of triangles your video card has to draw, so it might be faster to draw a big building made from megaprims than one that looks the same but is made of lots of smallers prims. Perhaps someone will clarify that or correct it.

You should get megaprims because you can. They're free, and you might find a use for them. They won't hurt anything sitting in a box in your inventory.

There are some problems or limits with megaprims. One limit is that each face can only have one texture on it, and textures in SL can only have so many points by so many points. So if you want to make a 256 x 256 square to be a lifesize ground surface, there's only so much detail you can put on the image, whereas if you made it out of a grid of 10 x 10 meters squares, each square could have a separate texture, and thus your composite surface could be immensely more detailed than the same surface made from one prim with one texture.

There's a still current thread at /327/af/259306/1.html with a list of free sources of the new megaprims.

a 666 x 666 x 666 prim would be able to rez in a sim(I think), but you'd want it phantom or you'd go flying XD As long as the centerpoint is in-sim it should be fine. I've rezzed a 256x256x1 on the edge of a sim, with about 100m off into the void, so there wouldn't be a problem in all likelihood.

Also, it would not be visible unless you were 2 1/2 sims or so away from it's centerpoint, or high enough in altitude.

Furthermore, I wouldn't recomend it unless you OWN the aforementioned sims. Otherwise you're violating the TOS, and probably gonna cause some lag too, though I dunno how much.

The new batch of megaprims has a huge number of sizes. Ones like 30 x 20 x .5 are more likely to be broadly useful than giant ones.

To fully appreciate the the 666^3 Devil Prim, one should own a 3 x 3 grid of sims, and rez it in the center of the center sim. Then you could fly around the perimeter of your estate, looking at your Prim from Hell, marveling at it's demonic immensity.

... or rez it at <128,128,333> on an island then hollow it, or rez it as a tube with .05 hole on the Y-axis and 90 degree X rot

/me snipes at Suezanne.

The possessive form of it has no apostrophe, debbil-woman ;-D

i had asked this in anther thread but never really found the answer heheh..
what is a safe size before you have to make a mega prim nonphysical?
is it as soon as you leave the default bounds set by sl or is there a size we should and should not go physical or non?

/me remembers why he likes Annabelle so much

That is an error I have to correct quite often.

For decades I coudn't remember which way was correct. There's no logic to it. It's just arbitrary.

At least now I can finally remember which way is right and which is wrong, but I still type it wrong and don't notice it.


Far more disturbing to me is my increasing tendency to make mistakes like typing their instead of there. I used to not have that kind of problem at all. Now it seems that I will sometimes start doing them backwards fairly consistently, which to me is something worse than just getting them wrong at random occaisionally. "Occaisionally" is another one that I have always had trouble with.

The Flock browser has built-in spell check, but it won't deal with its versus it's.

I've tried using the Grammar Slammer grammar checking program on forum posts but it's way too awkward.

i would really like to switch to no capitals like many do in chat but when i try i always go back and change it, except in this paragraph here which is an example. i would love to be able to not use the shift key. shift keys are bad. i just had to uncapitalize parts of this example paragraph.

I recommend adopting the use of "ther" in both cases, as it is clearly an insignificant typo and its use is free from worries that one's literacy or spelling prowess might be called into question

I think the new large prims were limited to 256m. Nic's custom viewer to 100m.
And, I think, that calling a prim by a satanic name and a size as you mention would be just asking for trouble.

You might be right, perhaps something like "Griefer's Delight" would be better.

You there! Child! Are you a Son of Adam?

Would you like some Greifer's Delight?

Sorry, the closest I made was a 64x64x64. I guess I was focussed on making "good" megaprims, for structural purposes. I wanted walls , platforms, and domes and parts for big airships. Some of the dimensions I made ranged into 128... but that was only because I was making things like 2X,1X,1X... so 128x64x64

How did this go from Bay City to Megaprims? lol

I know about over 10.000 megaprims but no 666x666x666.
It gets VERY scarce in sizes above 512 along any axis, most focus on sizes<=128 , closest it 600x600x? or many 512x?x?

hmm, I concentrated on binary powers and increments of 5 & 10m when I was making my megaprims. There were very few above 30m because my parcel isn't all that big, and even building on a full sim there are more uses for modest sizes that really massive ones.

That said, I couldn't resist a matt black 10x40x90m prim I called "My God, it's full of stars!"

damm i have a prim i think its 69000x 69000 something mad like that ive rezzed it and shit i have a whole sim in my pocket

That would be more like 72647 sims. (OK so I rounded down.)

A sim is 256 meters on a side, and 65536 meters square... and god hope I never come in contact with a 69000x69000 prim XD it would eat the grid o.o
