Prim Drift?

Last week, I logged in to find that a virtual earthquake had hit my house. Every single object was displaced. I had a friend help me put everything back together again.

I logged in just a few minutes ago to find the same thing. What the hell is happening, and how do I keep it from happening again?

Is my house on a fault line or what??

I've had the prim drift thing too, but never to that extent. Holy cow!

About every 2 weeks or so I have to walk around my shop and reposition floors and walls, but they're usually only a point or two off.

You didn't build on San Andreas, did you?

Last time something like that happened to me, it turned out to be a cache discrepency. Log out, clear your cache, and then log back in. See if the problem's still there.

Another thing that might help is to replace the prims that are repeat offenders. Sometimes prims just get "damaged" and decide to do their own thing over and over again. Shift dragging the original to leave a copy behind and then deleting the original usually solves the problem. Also, whenever possible, build by number. Prims that have been dragged and scaled with the manipulator handles seem to be much more prone to this kind of thing that those that were keyed into place. There seems to be some discrepency between what the manipulators tell the system to do and what the numbers tell it. Usually the numbers win.

Hot damn... Katt, does this just happen on your house or are the peeps next door and in other parts of the area affected too? Check to see if it's region-wide, if so you should prolly let a Linden know.

Thanks! But... uh... that's all Greek to me LOL Torley, it seems to only happen to me. Today when I found my house like that, I checked out the neighbor's, and his seemed to be fine. BUT... I'm wondering if this could be a problem with this particular lot.

I've had the same problem in various sims and have resigned myself to repairing the walls whenever I get a chance. It seems to happen best on huge stone walls like the ones I have in Sand.

There is a serious bug introduced in 1.6 where there is some sort of race condition between numerical input of prim locations / dimensions and the actual updating of the primitive.

In English, you type in a number too fast, or with a lag spike, or doing work across a sim border, or some kind of wonky condition, and the sim and asset servers seem to get confused as to where / how big the prim really is.

It's an annoying bug, from my observations I believe it's a natural result of a centralized asset server system, and I'm sad to say I have only found one way around it - delete and replace wonked prims. =(

Ironically, nothing from pre-1.6 ever does this to me.

A confirming data point to support Chosen and Hiro: I helped a friend "fix" a continually walking house by rebuilding it prim by prim. After a week of jiggling around, the "new" build has stopped moving. In this case, the build was greater than 15m from the sim edge (measured) and was built from the inside of the parcel (i.e. not from the 10m danger zone).

I've noticed what may be a related phenomenon, where textures applied to even a basic cube need a few "selects" before they stick. That is, when applying a texture to all surfaces (not select surface) the texture box will often show "multiple" until I've changed it a few times. If these phenomena are related it sounds like it may be that asset DB sets are being timed out without retry. Eep!

I regularly see a general drift of up to 0.005 meters, probably due to a sloppy rounding error somewhere.

I ended up putting a script in the 20 pieces of the high-rize that will return them to their starting positions on command. Got tired of doing it myself.

The safeguard bars on top of my house kept resizing themselves back from 1 to 10 in Z scale until I unlinked them... I'd be fixing them, then going somewhere else and or just turn around and it'd be back huge :/

During development for the Game Dev Contest, DNA built an 800+ prim tree to have prim drift set in the next day. I thought we lost him in SL for good. I convinced him to move onto the next build and go back to the tree when he didn't feel like tossing his monitor out of the window and like a hero he came back and fixed it a few weeks later.

If I had built that tree and got prim drift on it, I would consider throwing MYSELF out a window.

The prim drift problem has gone on for way too long - it is ridiculous. I have given up working on my house in Mavericks because I have lined it up so many times I have lost count, only to have the prims drift apart and come out of alignment. Other plots of land I have are fine - it seems to only affect certain places. Regardless, there is zero reason that we should have to be realigning our builds - there is no excuse for this problem still remaining after all this time.

Too right ! It's almost every single day I'm fixing one thing or another due to this problem, perhaps we should petition for a fix ! ... !!

Where *is* the Metaverse Justice League when we need them? Help us MJW, you're our only hope!

No kidding. I have two of my houses sitting on the property where I live. Well, as time goes by, these houses sitting there start getting ever so slightly out of whack. It irritates me, because I KNOW they were perfect when I made them.

I hope they are sitting in their boxes still as perfect as I was able to make them. I need to get some out and compare.

Wow... what a beautiful tree! Is it still inworld?

It's kinda sad just how much inexplicable crap still isn't fixed.
Get on the ball, LL, or your userbase will drift too far away....

Have to say that I have not experienced prim drift a whole lot, but I get a similar problem that causes almost as much vexation....Texture drift.

For a while I thought I was just nuts and missed sections of my glass block wall and tiled floors, but when I started taking notes, it found that certain sections of the wall simply would NOT hold a texture where it was put. This causes no end of grief to me, since I take pride in my home and I like to align my textures so that no "seam" shows. With the floor, I can sort of mask it by throwing an area rug down, but the Glass-wall is really an eyesore...

Has anyone else had texture drift?

Sure! Arena (183,4... enjoy.

I quit building mazes the day I was just about done with one and I discovered that I could just walk right through the walls. At no point were the pieces ever phantom, but they acted like it. I TPed away and back. All the pieces were shrunk. The maze is built small by a script and then resized by dragging a handle. Resizing that way does seem to be crap shoot as to whether or not it will work. I got fed up with building that way.

Yep. Most noticibly, the inside faces of 2 hollowed and cut cubes I use for doorframes always shift textures whenever I'm not looking. (I actually have stood there and watched them, and they cleverly didn't move) I set them at .5 and 20. and they always set themselves back to around 50. and 50. so it looks awful. I just gave up adjusting them and colored them black so my undies wouldn't bunch up every time I looked at them, and sometimes they manage to shake off the color as well.

I've tried checking sim lag before I reset them, resetting them and taking them into inventory and replacing them, and even deleting them and starting over, none with any noticible effect. No idea how to get them to stick.
