I'm sorry I can't really provide a ton more info for this question besides just screenshots, because I wouldn't even know where to begin but: anybody know why I'm getting these weird horizontal lines?:
They are not visible in the solid view:
And I only have a basic lighting setup and scene (3 area lights, nothing in between the lights and this object, simple plane in background. Blender 2.9, and just a basic scene I dropped the objects into. The material is just a very basic material I made by saying add material and then setting the color. No nodes or textures or anything.
But none of the solutions offered seem to fix it (setting the origin point or scaling)
