very subtle and only in the distance. kind of low priority but noting it here since it is technically an error.

Alright, I can see it on my screen.

  • It's more obvious down -Z.
  • Go far outside the region blend area, which has it's own artifacts.
  • Turn off dual scaling, but keep autoshader on.
  • Disable height blending to make it more obvious. Play w/ blend sharpness for an interesting take.

It is unrelated to:

  • Noise texture
  • Macrovariation
  • Vertex normals
  • Worldnoise
  • Meshes

It seems to affect only the autoshader, on lod 1-2+. It gets worse the higher the LOD, and is invisible on LOD0. Perhaps there's a precision or an off by one error in the autoshader.
