Has anybody else had massive issues with ambient occlusion when exporting to USDZ/GLB? My geometry gets covered in these crazy patterns of black shapes. Exporting without AO looks as it should.

It sure would be nice if it worked properly since the AO adds a nice level of detail.

You need a lot of samples to make AO look good. Also take care care of correct normals. AO look pretty good on assets with a few parts or large part (IMHO). AO doesn't work with animated scenes.


May you share a screenshot or sample?

Here is a very zoomed in look at what I'm getting. This is specifically when exporting for augmented reality. I use ambient occlusion for static images with no problems; it seems to be a USDZ/GLB issue.

Edit: I checked all the parts to make sure the normals were correct before exporting.
