Is it illegal to use mega prim on mainland?

Crashing does not necessarily equal lag.

"... on the mainland, if you don't want the lindens to return your prims."

Again, I ask, why not terraform the void on the mainland? It doesn't harm anyone if you do with with small (40m, say) megaprims, and the effect can be stunning.

Because it's technically "extending beyond your land".. and it's encroachment.. even if that encroachment is onto "nothing"..

We live in a borrowed world, and at any moment, the lovely coastal land that you've owned for 2+ years, could suddently become riverfront if LL decides to add a sim "over thar".. it's happened before, and it will surely happen again.

These are the "basic rules" that would seem to keep you in the "safe zone" of not getting your prims returned by the Lindens. Terrarorming the mainland void, and/or extandingg huge prims that cross region boundaries, I think, is a reasonable "rule of thumb" to avoid.

I'm sure there are going ro be edge cases where the lindens will think this is acceptable on mainland.. but if you don't want the lindens getting riled up at you, I would suggest not dropping 2048x2048 multi-sim megaprims. It's certainly something *I* would never ENCOURAGE new-users to experiment with.

Have you ANY statements by ANY linden that they will return megaprims (or anything else) extending into the void, or treat it as encroachment?

Yes, but in the meantime, you're not encroaching on anything.

What's unsafe about getting your prims returned by the Lindens? I've had it happen a number of times, it's no more painful than getting them returned by anyone else. The only thing you should care about is getting them returned when you're actually using them. After a new sim has been rezzed in the void is hardly an example of that.

Now you're being silly. I never suggested dropping 2048x2048 megaprims, I specifically mentioned 40m or smaller ones.

I hear normal prims will also be removed by Lindens if they cause problems. Mega prims aren't illegal, just easier to overhang onto others property, also keep them away from si edges.

Certainly Megaprims USED to cause lag, back in the days of Havok 1.

However nowadays the only lag caused by them is client side.

I remember that larger megaprims caused some performance degradation when placed on region borders. I noticed it myself back when I had my own Openspace sim (*stifles a tear*).

Now with the new physics engine I do not notice any performance impact anymore. I guess they are OK.

And if you rez a cube the same size made from 10x10x10 regular prims, there's no lag?

Prims up to 100 metres should be made the norm.....as should being about to hollow them to 99%.

No 100m is too big IMO, I think 50m is fair.

Should be a power of two. 64 perhaps.

128m like some other places.

No. I'm quite happy with noobs not being able to rezz 100m physical spheres everywhere, when they have the skill they will find larger prims, most of these new builders wouldn't own anything bigger than a 512m plot so why give them such big prims as default sizes.
Maybe going up to 20m would be ok, but bigger, no thanks.

Since a 512 is 16mx32m then the limit should be at an absolute minimum 16m. 20m would let them make prims too big to fit on the plot.

Other sites which allow bigger prims dont seme to have this problem... The availability of bigger prims free up prims on a plot and allows more detail in builds.

And if noobs want to rez huge spheres they can easily be obtained in far bigger sizes than 100...

where ? Im interested !! Ive seen other sites offering 100m and a 99% hollowing feature but not 128 ....

When the megas will be "legal" they will be included in the client (read: not forced back by the server when resizing/creating) to being used by anyone, until then LL doesn't want em (otherwise they would have set the limit to 100 not to 10.. na?). It's pretty clear to me.

I disagree. Megaprims ARE allowed, on the mainland or anywhere else. ANY builds, mega or not, that cause problems or encroach on your neighbors are subject to AR and may be returned to you by LL.

And if they are allowed why you can't size a prim up to 100 meters? Are you telling me that Linden Lab is deliberately limiting the client and servers because they are sadists?
You know that in a recent server deployment they left open (by mistake or not) the server size enforcing, to the possibility to create megaprims returned back for a while, but then they hurried (2 days) to deploy a new server to fix the "problem"? That's pretty different than "allowing" megaprims, unless (as i said) they are sadists and they wanna look at us managing with our inventory to rez any sort of prim to find the "good" one, while the "create" button (and resize) would just works.
Hmmmm...

You're not cleared for that information.

No, maybe 10m is perhaps just the largest size they want any newborn being able to rez.
Other grids with 128m limits have mainly experienced builders rezzing things, most griefers would have a field day on a alt grid rezzing replicating 128m mario cubes on a physics engine worse than havok1 where they are sharing 18 sims per server. How to take half a grid down in minutes except there's usually only 2 or 3 people there to notice.

10m was selected so the maximum radius was 5m, when they were doing inter-sim physics within 5m of the border. They haven't done inter-sim physics in a long long time, 10m is really just a leftover.

Did you figured that those "replicators" uses a prim stored into the object inventory and they doesn't "rez" anything from scratch, so actually they already works with 10,20,128 or 128.000m prims..?
And limiting the server to *anyone* to 10 meters because the doesn't wanna new born rezzing larger prims? Whenever i think it is a "ehhhhhhh?" reason, wouldn't be easier to limit em only on the interface? They have introduced a server-side limitation *after* the users started to use self-compiled clients (or proxy/or unoficcial client) with the limit disabled (none of these operation would be performed by a "newborn" because they doesn't want *anyone* to create megaprims.
So again if they doesn't allow the megaprim creation by *anyone*, i don't see how they may allow or support their usage, especially on mainland, unless.. as i said.. they are just sadist.

the only thing that would bother me with creating mega prims would be that griefers could too..instead of crashing a sim at a time couldn't they crash whole estates much easier in less time?
