I made a model of a small robot for my animation. It has three spheres cut in half attached to the bottom (For now i just cut them and joined with the rest of the mesh, without interior faces). I am saving my models as FBX always and texturing them in Quixel Mixer. The problem is, when i try to bake Ambient Oclusion map for this one, every time bottom spheres are whole black. Of course i understand that it somehow means that they are behind bottom face and light can't get there... but i saw a lot of models with elements on theit bottom and they weren't black on AO. How to fix it?

enter image description here here is an example of one of AO mapshere is one of the first AO baked for this model with some other black areas (fixed now) but focus on black circles Here is how it looks in Quixel Mixer after adding AOHere is how it looks inside the mesh bottom of a model

    $\begingroup$ Have you checked your meshes for flipped normals before exporting to fbx? $\endgroup$

  • $\begingroup$ Thank you! I didn't know i can display flipped normals in that way, you probably just gave me a solution for most of my problems. $\endgroup$

  • $\begingroup$ You're welcome. Blender's UI hides a lot of little helpers. It's really worth exploring because they are all useful in some cases. $\endgroup$
