Question 2D Pixel Perfect Problem

Hey guys,

some weeks ago I started to setup my first unity 2D project using Unity 2021.3.6f1 and URP template. I studied articles about how to achieve pixel perfect 2D and watched quite some youtube tutorials on that. As I am a experienced programmer in my daytime job, I quickly extracted the essence of how pixel perfect rendering works and how to set it up, but there is one problem I cannot seem to solve since two weeks:

• I set up my project using URP and Pixel Perfect Camera, that calculates orthographic size accordingly.
• My PPU is set to 128, reference resolution 640x640 (for now), pixel snap is on
• All of my sprites have a dimension of 128x128 pixel, point filter and no compression and are rendered in tilemaps
• Whenever my sprites' dimension are exactly matching PPU they get rendered distorted.
• If I put my PPU higher, e.g. to 256, my 128 textures are rendered perfectly.
• If I switch out my 128 textures to smaller ones, e.g. 64 or 32, they are also rendered perfectly on 128 PPU

Does anybody have some experience with an issue like that? I just have no clue why this behaviour is only there when the PPU and texture dimension perfectly match. Feedback is really appreciated, thank you!

 

If you could post a screenshot or video of the distortion, that would be helpful to diagnose your issue.
