black noise on static mesh

Hi,
I got an issue with rendering my mesh on ue, its generating random black noise point ( see on the left side of the image)

I can’t figure out how to get the same rendering as on the static mesh editor on the right.
I didn’t found any information about this on the site, I guess it something about AO but nothing approach my issue.

Thanks for any help!

Yeah, it looks like AO. Disable it(set scale to 0) in your post process volume. Dont forget to create one if you havent already and set it to Unbound.

Thanks you! I should real more about this PostPro volume !
