Properties: Quality (Experimental) = Texture Size 12 textures.
This is the same property if you do it manually for 12 textures. You can always use this property, except when you need to adjust the focus for each camera, the depth, or a custom post-process, then you need to do everything manually.
I noticed that you set the texture quality to 7680 (Quality (Experimental) = 7680 ). This is a lot, so rendering takes longer.
I recommend that you just disable the anti-aliasing property, and then all the borders will be very clear.
Set the texture quality to 4096 and compare it with the 7680 you made earlier.Then try 5000 and compare with 7680. I think the boundaries will be very clear.
Please write to me, does the solution help you?
I noticed that there is a small seam at the bottom, I think in the post process you have the bloom = 0675 or vignette = 0.4 parameter.
To reduce the seam or remove it, you can set the value to 0.
bloom = 0 or vignette = 0.
