Material artefacts

Hi everyone,

I’ve stumbled upon an issue when generating a geometry shape. When I apply Material, no matter which one, and reduce Alpha, it creates weird artefacts on the surface. I can see them even on the preview of the MAT operator. Is it possible to get rid of them?

I’ve already went through this topic Transparency | Derivative and I assume my issue could be related to depth rendering, however, I haven’t found a solution. Really appreciate an advice on that!

Thank you,
Anya
