I'm using RingGeometry in my scene, at start the rings are renderer perfectly, but if I rotate the scene, artifacts appears on the rings. I tried CircleGeometry and I have the same result. The circle and the scene has an alpha channel because I need to variate the rings opacity.

  • Looks like z-fighting. https://en.m.wikipedia.org/wiki/Z-fighting – M - Jan 06 '22 at 19:25
  • I think it’s because you should add [minimal code to your question](https://stackoverflow.com/help/minimal-reproducible-example) so others can see where the problem is taking place. Otherwise the best we can do is guess. – M - Jan 07 '22 at 17:18

Thank you @Marquizzo that was it. I have and invisible circle at the same position (used for raycaster.intersectObjects), even if it was at opacity 0 it was causing z-fighting. I moved this invisible circle on the z-axis and the render is perfect now.
