Mesh Ambient Occlusion

Calculates mesh ambient occlusion

Rays Samples: Amount of rays for sampling
Rays Angle: Angle that rays direction will be randomly rotated. Bigger angle will give more accurate results but with more noise

External Mesh: Uses external mesh that rays will hit from main mesh to calculate ambient occlusion map

Attribute: Name of the thickness value attribute on point domain

Warning

Node can be really slow depending on mesh density and rays samples. You can “bake it” by applying geometry nodes modifier and the “ao” attribute will be stored on the mesh
