In my blender file, I have a simple castle in which when I try baking the Ambient Occlusion it generated a black texture. How can I get Blender to bake correctly instead of this black texture? Picture of UV texture in blender

I been reading on forums about this problem which mentioned about inverted normals but my normals or overlapping UV but I generated another without overlapping UV's and received the same problem. They also being negatively scaled but this model has positive scales ;(

Thanks in advance!

Blender file attached here:

  • $\begingroup$ I should be something related to the file itself: importing all the objects in a new file allows a correct baking. Is it the same for you too? $\endgroup$ – Carlo Dec 22 '15 at 2:45
  • $\begingroup$ Sorry for the late reply but yes I resorted to doing that afterwards. There's no problem when I export the mesh and reimport it into a new file but I wanted to know why it happened so I could prevent this from happening again :P $\endgroup$ – TheMuffinCoder Dec 24 '15 at 23:09
  • $\begingroup$ try doing ctrl + n in edit mode and then try again. $\endgroup$ – Smekens Younes Mar 2 '16 at 20:48

Try to set Environment Lighting to 1.0 in the World tab. I have tested it now and it bakes AO correctly then. The funny thing is that you dont need to check the Environment Lighting checkbox and it still makes the change.


I had one part of a mesh acting this way and fixed it by recalculating the normals.
