"Blend Seams" in tri-panar doesn't work

Tried also the material graph, does not work on multiple files.

Can someone help me?

KS v2023 - Win11 64

Thank you!

Would you be able to share this file as a KeyShot Package / .KSP? If so - please send to jordan@luxion.com via WeTransfer.com. I would be happy to take a closer look; it’s a bit tricky to diagnose without inspecting.

If not - can you share that marble image file and / or share a screenshot of your Material Graph?

I would try to tilt the texture for a few degree. You can use move texture to solve.
I guess this effect depends on the shape of the part.
A tilted texture should not disturb with this marble texture

Good luck
