wrong preview of material(cycles)

I’m doing something bad?
mi preview is wrong, like flat projection
cycles preview


Hi, could you upload the .blend with packed texture?

Cheers, mib

AFAIK this is expected behavior.
On top of this textured view seem to use Flat projection while rendered will use one you set in Image Tex node.

untitled.blend (4.68 MB) here is .blend
