Estate owner is using 256x256 MegaPrims which overlap other openspace sims.

I'm pretty sure this is what they are doing and wondering if I should be concerned from any technical viewpoint?

I rent a whole openspace on a private estate.

Next to me the estate owners have created two new openspace sims, both of which feature just 2 islands in their whole openspace area.

To make the water extra blue. I'm pretty sure they have positioned a 256x256 thin, transparent light blue (ish) megaprim centrally on each of the 4 islands on the two openspaces.

Due to the megaprim sizes and island locations the megaprims are not only overlapping each other but also overlapping "off world" on some sides and slightly overlapping neighbouring occupied openspaces on the same estate.

You can't see them on the other occupied area as the texture/colour fades in from totally transparent at the sides, to a light blue central to the new islands.

Apart from the fact of it being there (but I guess it's their estate so they can do as they wish) might doing this (multiple 256x256 megaprims overlapping each other and other neighbouring sims) cause any performance/technical problems?

Here you can see how they have used 4 of these megaprims (centralised on 4 islands in 2 new openspaces) and how they are not only overlapping each other, but also overlapping neighbouring sims.

Link to screengrab here:




I have found they are called "Naima Undersealevel Emerald Water" by Gene Replacement.

And I guess where designed at full sim size 256x256 with bright blue/green in the middle, fading out to total clear at the edges.

And looks fine, and would be fine with one central island in a sim

but due to their being 2 islands in the sim and one each of these megaprims for each island they are overlapping all sorts of things.

No one know anything about this?

I thought I read that overlapping megaprims across multiple sims (openspaces) was not a good idea.

Seems like an odd thing to do but is it causing you a problem on your sim?

What they do on the other open space sims won't affect your sim cause they could be on different servers.

For example, during new server deploys, one of my open space sims will be updated one day and the other 3 at another time.

If you don't like them because you feel they intrude on you, just contact your landlord politely.

And someone needs to tell Naima that using the new mega prims would be better as the old Gene Replacement ones have much larger bounding box from what I hear. (Naima does really neat water effects by the way...love his work).

As far as your object count: No, it counts against the sim where the object is actually rezzed (approximate center bottom of the object. Despite the object appearing in your region, attempts to sit on the object will fail as you aren't in the same region as the prim

As far as interesting glitches: Nothing that I could find about it is particularly harmful, and it's even possible to move yourself out of a region without leaving it this way, the result being that only objects and avatars on the same region as you appear online (with the other sim(s) in view entirely missing in an edge-of-the-world kind of way).

If you want to see a particularly dramatic example, go to the Ahern Welcome Area and stand at Bonifacio 252,252 <URL:http://slurl.com/secondlife/Bonifacio/252/252/40>, and face the round island in the middle. Using your flycam, look at the opposite (Ahern-region) side of the island, and sit on the island's bench. Within a moment, Ahern, Dore and Morris regions should disappear from view completely, leaving open sky below your feet as you overhang the edge of the metaverse! I presume this works with sitting on the off-region side of any object bordering a region boundary.

I use a *HUGE* 1000m+ by 1000m+by 200 or so prim in the center of a 4 island square.

With your draw up high enough this square of islands looks like it has a *huge* sculpty mountain range all around it!! =) *neat effect factor is high*

Never seen any performance issues due to this...except for a side-bug related to non scripted sitting inside the bounding boxes of sculpties.

As far as overlapping the only effect i can think of would be if that they are not set to phantom. Not sure if H4 fixed this, but i remember an older issue where lots of people standing on the same overlapping megas could cause problems.
