I use Unreal Engine 5, the grass is from quixel and it’s the highest quality.

I use a 24mm lens with an aperture of f/2

I render over the Movie Render Queue with a Temporal Sample Count of 16

As for the console variables i have:

r.MotionBlurQuality 4

r.MotionBlurSeperable 1

r.DepthOfFieldQuality 4

r.BloomQuality 5

r.Tonemapper.Quality 5

Any ideas?

Hello!

I have the same issue with UE 5.1, did you find a solution?

I tried to set the following variables with no result:  
R.TemporalAA.Upsampling 0 (default 1) \> This variable seems to be the key according to this tuto [This Will Improve Your Depth of Field Quality Forever – Unreal Engine Cinematics](https://www.youtube.com/watch?v=osHpBZ47ZfU&t=336s&ab_channel=WilliamFaucher)

r.DOF.Kernel.MaxBackgroundRadius 1 (default 0.025)  
r.DOF.Kernel.MaxForegroundRadius 1 (default 0.025)  
r.DOF.Scatter.MaxSpriteRatio 1 (default 0.25)  
r.DepthOfFieldQuality 4 (default 4 Scalability Cinematic)  
r.DepthOfField.MaxSize 400 (default 100)

Thx!
