artifacts on material

So I’ve got my model, it’s rigged, the materials are mostly done. But when it moves, there’s this strange shimmer on a piece of it with a kevlar pattern.

It couldn’t be captured, so I’m wondering if it;s some sort of optical illusion, or an issue with the normals, or just plain old aliasing? It only shows in the final image and roughness buffer.

Hey N67nightmare -

I suspect the answer is no, but can the flicker be seen when doing a video capture? It would also be helpful for you to highlight where on the photos above you are seeing the shimmer itself.

As an educated guess based on your descriptions above , I would suggest looking at the roughness values around the edge of your kevlar and see if you have any places that may have a value over 1.

Thank You

Hi, thank you for the reply. I tried launching the game instead of just simulating in editor, which seemed to remove the effect. It appears to just be a glitch in the editor rendering. Thank you for your time.

In your modeling software your model has overlapped surfaces (almost in tha same xyz space) that is why you get those flickers
