Grain flickering on .glb model (with grain disabled and enabled)

Model has black squares with or without grain and with different lightning
What can be cause of that?

Also on macs and some laptops - there are no lightning applying on a model, may it be a problem with textures or something?

Welcome aboard!

Are you able to setup a repro in the Playground ( If you need to make the model accessible from the playground, see this doc page.

Also, could you test it with another viewer (like and see how it goes?
