I've never had this issue with building before. I've made a platform for my house which doubles as the floor. I've used no mega prims (this time), and as I circle my avatar around the sides of adjacent prims show through eachother. Its happening on the walls now as well.
Even when trying to put a prim over top to mimic a carpet, as I move my camera around, half of the prim disappears. I just don't get it. Is this a bug? I've been searching the foruim for over two hours looking for a reason.
*Update. If i build just a standard wood prim, it doesn't do this. Could this be the texture I'm choosing? I don't know.

Basically SL (and other 3D apps) don't handle alpha channels and transparency as well as they might. There's a sticky about it in the Texturing Tips forum, 4th thread down when I looked. |

It might possibly be a solid texture there that was inadvertently uploaded with an alpha, and giving you the usual sorting sillies.
Enable the advanced menu with ctrl-alt-D. Select one of the strange-acting prims, and press shift-ctrl-alt-T (or Advanced->Rendering->Selected Texture Info). That will print some texture details in the chat area, and if you see alpha in there, you probably have found the culprit.

"512x512 alpha on face 0 1 2 3 4 5 " So would the answer be to just take the texture and save it as a jpeg in PS and re-upload as to uploading a png file? |

If it's a texture you made yourself, and like to work with PNG, try using Save for Web... where you can explicitly turn off transparency. Or, from Save As..., choose Targa format, and make sure alpha is not enabled. |
