Ambient Occlusion baked texture has strange pattern

[Tyler24031432c8q8]

When I start a new project with an FBX file from blender 2.83 and I then bake the mesh maps the ambient occlusion map texture has a strange pattern as shown in the picture below. The pattern bleeds through tany materils that I apply and smart matterials follow the strange pattern.

Anyone have any ideas as to what is causing the strange pattern?

Can you post the fbx - it looks like an unwrapping issue

Hi Dave,

Thank you. Please find attached my fbx file.

Hi

In Ambient Occlusion bake settings try Ignore backface - always

In Thickness try raising the Min Occluder Distance to 0.002 (relative to bounding box)

After that, you might though want to redo your unwrap as there is some nasty stretching in parts of the surface

Thank you Dave.

I have made those changes and the strange ambient occlusion pattern has completly gone.
