Weird stripes in mesh when transparent material is attached (Eevee Renderer)

Hello, maybe someone has an idea what I can do here:

I checked the normals, those look good.
As well I checked if there are overlapping faces or open edges,
I have no seams whatsoever. so it should be all the same smoothing group

I also deleted the faces and tried to make new ones didn`t work either. super strange. Maybe there is something I overlook?

I am really not sure what else it could be.

Happy for any suggestions.

EEVEE has always had issues with glass/transparent materials. There are work arounds but I typically steer clear of using glass/transparent objects in EEVEE and just stick to the tried and true Cycles. There are youtube videos of transparent setups for EEVEE out there though.

Okay thank you I will check this out. But it`s good to know that this can occur in EEVEE. I was really out of ideas.

There’s a good glass setup here:

See if that works for you.

Have you tried changing alpha setting for transparency in render setting? Try alpha hashed.
