building house floor rendering problem

I don't know if this should go in the texture forum but. I have started building a 30m square house made of 9 10m X 10m X .25m Cubes all rendered with a marble texture. Once that was done I walked around the top and it started showing the ground below me or parts of the floor lower then the others. Dose anyone know why that's happening the only thing i think it could be is that my computer is not rendering it correctly. Any suggestions on what i might be or how to fix it.

that's what it looks like it's always at on side of my screen if i turn and look at it it fixes but then another place goes wrong.

If you post a location I'm sure someone will take a look.

i cant post a location because the only place i can put it is a sandbox and that get's wiped

This one is easy. You picked up one of the marble textures from the SL Library in your inventory, right? There are several freebie marble textures in SL -- at least one in Inventory -- that are 32-bit textures. They shouldn't be, but whoever created them screwed up. When you use them, they generate transparency. You are seeing what we know as the alpha sorting problem. The way to beat this one is to use a different marble texture. If you really like the texture you are already using, you can try downloading it to your computer and resaving it as a 24-bit texture -- if you have mod permission for the texture. Otherwise, you're stuck with it.

Yup, it's the alpha sorting glitch. For more information on that, see the sticky on transparency at the top of the texturing forum.

Rolig's right. Use a 24-bit texture, and you'll be fine.

I really wish LL would get around to replacing those improperly saved library textures. It's only been what, five years? It would take them all of five minutes to replace the existing assets with new ones, give them the same UUID's as the old ones, and then every instance of this problem would go away.

when I first started making textures I thought more bits are better so I made some concrete and brick walls 32 bit instead of 24..

I think LL is getting rich on our mistakes .. upload fees ..

Yeah, no doubt. My doctor is making money off my mistakes too. I can't blame the doctor for not telling me it's dumb to put beans up my nose.
