Title: Triplanar + Subdivision Surface causing glitches
Post by: unsergio on 2024-09-04, 15:03:48

When I activate Subdivision Surface with triplanar active some glithes are appearing.
Is this a known bug? Or a normal behavior?
Tested in v12 hotfix + v13

Thanks

Hmm, just out of curiosity, is the glitch still there if you lower the bump strength?

Thank you for reporting this!

Yes it is. I went crazy with it to make it more obvious.

Roger that, makes perfect sense. I think our support team is going to take this over. Thank you for reporting this!
