What could be causing this artifact on my WorldAlignedTexture?

I made an extremely simple material using WorldAlignedTexture with a seamless texture. For some reason, I’ve noticed that there is a repeating artifact affecting the material that is not present in the texture itself. I’ve attached the blueprint for the material and a screenshot of the issue at hand.

From my own debugging, the artifact isn’t present when the texture is a texture sample, but it does occur when converted to a texture object, which is necessary for WorldAlignedTexture. Has anyone else experienced this? How could it be resolved?

Does it happen if you just use XY texture?

I think it might be just that, an artifact…

Thanks for your reply! Unfortunately, it does indeed persist when I use XY only.

I took a closer look at the texture itself, and oddly enough there is precisely one ‘dead pixel’. Unsure what caused this, but the original image file does not contain it, so my thought is that it must have happened on import to the engine. Strange.
