can anyone explain this to me??

well…i was working on a house model, and then i had to leave for a while. so i saved it, but when i came back, its like…pieces of it were missing.


is there any way to fix it??

You are missing something from the viewport or during the rendering process?

Are you using Windows, Mac OS or Linux?

trying ALT+H costs nothing.

you can also double check all your layers.

ill answer missing the pieces in both, viewport and render
i am using windows
tried already XD
i checked all of them…nothing
using blender 2.61 with cycles and bmesh
i only rendered with blender internal for it to be faster and clearer
