I have been tackling this problem for the last 2 days and I can't find any solution to it. So, I baked this smoke sim and test rendered it, It has some weird blocky shadow and reflection, I thought it was just a random bug, so I closed blender opened it again, and re-render it, it outputs the same result. I tried to delete the flow object and replaced it with something else, it still outputs the same result. Tried to delete the domain and re-do it, nothing changes. I am very confused on what's happening here. COMPOSITE

I have 3 view layers/render passes:

  • The smoke itself: The Smoke itself
  • Shadow Catcher


  • Reflection Catcher/Glossy Indirect Gloss Indirect

Maybe you guys can figure what's the problem, here's the Blend file link: https://drive.google.com/file/d/1P84r9d5UbGE-TWvDeEQERqG2zU_gcYc2/view?usp=sharing Thank you in advance!
