Hi, i am trying to convert a sample from Nvidia SDK 10 (Clipmap) to DirectX11, everything looks perfect but there is only one problem, if the sphere (or any other model) size is a little larger (I use a 20000 radius sphere), the model can not be rendered correct. see the image below.

any link or article is OK, thanks for your help!

PS:sorry for my bad English- -

Difficult to say from the screen shot, but I could guess that the amount of geometry gets quite large with a huge planet. Are you using 16 or 32 bit indices?

Cheers!
