I've posted about this issue before, but since none of the advice helped I'm gonna try again cause this is really really annoying.

I'm building the exterior for a house mod, and some pieces have started to disappear, not just in-game, but also in the CK. I can still double click on them and bring up their menus, but they are invisible. I've tried ticking off the "Full LOD" box as previously suggested to me, but that doesn't help. I can't figure out why these pieces are not being rendered when they're clearly still there. One thing I just thought of, but haven't tested yet, is that the piece in question is overlapping with a duplicate of itself (to create a larger piece for my purposes). Could it be that this overlap creates a glitch?

Basically, I can't proceed with my mod because of this, so I'd really really appreciate some insights.

That's weird. Are they just invisible or fully intangible? Can ya walk through them in game?

They're invisible, and have no collision affect so you walk right through them like there's nothing there. But the collision box is checked off too.

Usually when stuff disappears on me in the CK you can press F5 to force reload the cell. This reloads everything and also makes stuff that you hide visible again.

As for stuff sometimes not displaying in game... usually for me ticking in full LOD makes it show.
So I'm not sure what could be causing that, it sometimes happens for me too. Maybe if the object in quest crosses a boundary between two cells?
Just a guess.

Ok, I'll try that. Did the LOD thing, but no luck on that one. Could also very well be the crossing of a border, but I've had that confirmed by someone else that that shouldn't matter. I also have objects that do not cross any borders disappear on me from time to time, so I doubt that's it.

If that doesn't work you can try something else, this issue happens with me, normally when you select an object and press 1 if fades it out then press 1 again and it makes it invisible, they put this feature in so you can get to objects within an object like markers. the stupid part here is that the creation kit thinks you have done that on some objects therefor making them invisible, normally you are supposed to press Alt and 1 to bring them back but in this case that doesn't work either, If you are able to select the object either by the render window or the cell view while its invisible press 1 on it till its normal again.

hope this helps.

Some exterior objects, especially if you 'copy' them from somewhere else, tend to 'vanish' but still 'remain' in place.

What you need to do, is find that object in the object window, drag it into the render window, delete the one that does not want to appear (the old one) and replace it with the new object you dragged to the window.

If you double-click on the objects, you can get the exact X,Y,Z position and rotation of the old object, so you can put the new object in the same place.

I had objects vanishing in the CK awhile back and the only way I could get them to become visible was to delete them. They don't actually delete, just become visible. Try it.

Did you hide it by accident by pressing 1 on the keyboard? If so its name is colored cyan blue, just select it in the object list and then hit 1 to unhide it.

Thanks for the advice guys. I hadn't pressed the 1 key, but I deleted the object and replaced it with an identical one and now it's back. I'll keep an eye on it and see if it disappears again.

Ok, so none of this seems to work as it's still happening.

I replaced the objects with new ones from the object window. I hit F5 and they do show up in the CK, but sometimes not in-game. I hit "1" and toggled the visibility a full circle to where they're fully visible again. I checked "Full LOD", saved, exited and opened again.

It seems random which objects it happens to, although it does seem to happen only to ones I've dragged in from the objects window and then duplicated. It happens to both the original and the duplicate. Are they not allows to overlap? Some of them are overlapping in order to alter their total dimensions.

This is getting pretty annoying as it sorta fouls up my otherwise decent mod =/
