Decent looking 4k 360 video someone else has made:https://www.youtube.com/watch?v=AP7506nJoYM
My test: https://www.youtube.com/watch?v=wJRJvgZIgbc&t
I feel as if my renders are more grainy than other 4k videos I've seen but I'm looking for a second opinion. I followed the instructions in the documentation to make a 4k 360 render but I can't help to think it's not as sharp as it could be? Would a higher res resource pack make a difference?
Actually, yours (top) looks slightly sharper than the other one (bottom).
I wasn't sure, maybe I'm just paranoid? Also noticed I don't think I had optifine enabled which I usually do. As far as textures go though would a higher res texture pack make it look any sharper?
