Bake Texture

Hi,

I did a bottle and place some pattern on selected area… want to bake that so I can use it in bump channel…?
I tried to bake but “not valid uv tag”, there is not uv tag space.

I did unwap bottle but that pattern area is coming half circle and I think it will be hard to place pattern in photoshop over half circle shape so I think better bake texture.

Thanks.
Imran.
