bake not working

hi! i’m trying to bake a simple window into texture and normal map.
but it just doen’t work. all i get is an one-coloured square (and sometimes a square with a rectangle (the extact size os the window) inside).
does the bake feature needs an minimal object size to work??

when i ‘discovered’ this feature, some days ago, i was amazed. but now it’s driving me crazy. :ba:

.blend file is attached. if someone can test and successfully bake it, please let me now.
thanks in advance.

one more thing i discovered: i can succesfully bake texture, AO, and full render. the only thing doesn’t work is normals :confused:

All the faces are perpendicular or parallel to bake plane so really no good to use normal information.

i didn’t knew about that. after reading your post, i searched better about these mapping techniques.
so, in this case, should i bake a displacement map and use it as a bumpmap?!
thanks! :slight_smile:
