Maximum Altitude for building

What is the safest max height to build?

I want to put up a Spacce Station and would love to have it where it really belongs. In Space.

I've read that some have built as high as 4000, but the safest height is arounf 700 - 750.

Any suggestions for a fitting environment for a Space Station?

A normal prim can't be moved above 768m manually, with llSetPos() or llSetPrimitiveParams so that looks to be the limit.
However, it may be possible with prims marked as physical. IIRC, avatars are physical and they can certainly go above that limit.

Residents can't fly above 256. Residents can't stand above that height either. If you took object, sit on it, moved Z to 700, then click to Stand, it will not allow it, and you will fall through the object.

That's what I remember, too. So for all practical purposes place your space station such that its top scratches 768 m.

I think that you could simulate a view into space even at that altitude, by putting some starry props in front of the windows. But that's just an idea ... I haven't tried this.

I beg to differ. For me it works.

As long as the object is big enough to stand on it, then you can stand on it also at 700 m. That's exactly how I built a skybox: Sit on a normal box, change Z, then change the X and Y size, stand up and - voilà - you have a sky platform.

Yep, you can stand at that height without falling through. Falling off is a different matter

Something I have noticed at that height though is that flying seems to move you a lot faster so it's easy to go over the edge. You can't fly upwards from that height without some form of flight assist, but you can hover inches above the deck.
Is it just me or does anyone else get this?

I have my skybox above 750m and the only issue I have is with the vertical edit arrow on worn prims...it comes and goes as it likes.

Flight boosters take care of the other issue.

Have you been to the International Spaceflight Museum? If not, taking the shuttle ride might give you some ideas.

not true i have a shop at 500m
a theater at 650m
my lil cube for my vendor servers at 600m
and the current build im workin on is at 700m

i use a private workstation..click on it sit..tell it what height to go to then what size i want it 30x30..60x60 or 90x90...it comes with rails..different textures it wil even build walls and ceiling on it for privacy

i love bein up that high...quiet..peacful no lag i can just build and work without interuptions most of the time

Wow, thanks for all of the informative responces,,, and I'll definitely check out the International Spaceflight Meuseum!!!

Keep the suggestions coming!

a couple months ago there was a place called the mile high club that was at like 5k meters, i saw it via a freinds screen, was never there personally, and i never figuered out it was done.

The one caveat I've read about the upper heights is that you can *place* your skybox there, but *building* it at that height is difficult due to prim drift of some kind.

768 Meters is where normal building practices stop working.

200 to 300 Meters is where unassisted flight stops working, but there are numerous flight gadgets that will allow you to fly above that height. I have a pair of "Angel WIngs that Psyke created, and which I found in a freebie box. I have flown to over 4000 meters with them. And yes, it starts getting dark when you go that high! Oddly, I could only crack the height limit by flying forward, and looking up in mouselook. If I tried using the page up key to rise vertically, I still stopped rising at 200 or so meters.

I would not recommend actually trying to build anything above 768 meters altitude. The SL application isn't designed to handle it right. Those who have done so build at a lower altitude, then select the whole build and edit the Z-axis height to send the build higher. I haven't experimented with these methods yet, so I can't give you more detail than that.

Shockingly wrong. You can a skybox/platform/home/shop/whatever all the way to 760 without problems. I say 760 cause you need a few meters for walls and stuff.

I built two clubs at 750 meters - somehow everyone managed to stand/walk/etc

Infact the vast majority had no idea how high up the club was.

And Ejecting people was so much more fun - It was a long, long, long way down.

I'm not planning on actually building anything from scratch. All I want to do is rez the Space Station, and then furnish it.

Can this be done at altitudes higher then 768???

I *think* you cant have anything permently over those altitudes.

Like a vehicle can go higher but when it stops "flying" it wont stay there.

Prims will be returend, etc.

To make a furnished structure that is permanent firnished , etc. You probably cant go higher.

Life at 760 is great though - nice frame rate, less annoying fly bye people less neighbors, etc.

768 meters is the highest that you can "Rez" any object, but once rezzed the object can be pushed higher.

Above 768 you can't properly reposition objects either as they start to sink through the floor if you try to rotate or slide them.

That said, I have had no problems manually moving my sky box higher than that after it has been rezzed at a lower altitude, and you can still attache objcets to your avatar just fine at higher altitudes.

Well, from what I've read by all of your responces, it looks like 768 is the limit if I still want the option of adding or moving interior, or for that matter exterior furnishings.

Just wish I could have a Space Station in Space where it belongs!

A suggestion? Enclose it in a box of 10M x 10M flat prims, textured on the inside to look like space. That will get the space-like view through the viewports, even if the screen surface is only 5 to 10 M from the station.

But yes, except for a few novelty uses, you're far better off to stay below 768 Meters.

I have attempted to push linked objects higher than 768 and could not, they would automatically bump themselves back down. If I remember correctly, a single item can be pushed higher but linked objects cannot.

As pointed out, nothing can be rezzed (or edited, for that matter,) above 768 meters--the build engine simply shuts down at that altitude. However, any object, linked or otherwise, can be pushed above that level. I've had space stations at 4000 meters--great sunsets up there--and scripts run spectacularly well (I usually use that height precisely for testing scripts under prime conditions.) However, if you wish to refurnish your space station, you'll have to do it at under 768. If the station is modable, simply place your objects and link them to the station. If your station is NOT modable, you're out of luck. While you could, I suppose, create two objects below 768 (the station and a set of your furnishings linked as one object),then push them individually to 4000 meters, you wouldn't be able to tweak the X,Y, or Z axis of the furnishings object once they're above that 768 limit. This is extremely problematic as when pushing things over the 768 limit, the Z-axis reading is a bit fuzzy, and trying to align two objects will frequently result in it working one time, and NOT the next. (I've tried this and found that what's perfectly aligned to the floor on one rezz, is buried in the floor a second time, even using the same initial rezzing point and the same Z-axis settings to push the objects to 4000 meters. (I'm guessing this is the problem Isablan is encountering--you can get things up over 768, but it's a crap shoot to have it work well 100% of the time.)

My advice would be to rezz things wherever you want and surround them all with a space texture backdrop. If it's space you're after, that's really the only way you'll get it with multiple objects.

I have rezzed things higher than 768. If you try to move or edit them then they drop back down to 768.

Somebody doesn't have a flight feather!

Some clarifications :

Objects can be rezzed at any height :
- by drag&drop from the inventory, as long as there is another object to rez them on
- by an object rezzer (llObjectRez()) in a 10m range
- by dropping an attachment

Objects over 768m are also permanent, can also be edited, but cannot be moved by dragging their axis or changing their position in the Build panel - otherwise they go below 768m.

So if you want to place your station over 768m and furnish it, either fly there, attach it to you then drop it and furnish it without moving the furnitures, or furnish it first then place it and do that every time you need to refurnish it.

Notice : at 10000m and over, avatars appearance is not stable.
