Sampling¶

EEVEE uses a process called Temporal Anti-Aliasing (TAA) which reduces Aliasing. TAA is sample based so the more samples the more aliasing is reduced at the cost of performance.

Viewport¶

Samples: The number of samples to use in the 3D Viewport. When setting this to zero the viewport will be resampled continuously.

Temporal Reprojection: Reduces noise while moving the viewport or during animation playback. Can leave some ghosting.

Jittered Shadows: Enable jittered shadows on the viewport. Jittered shadows are always enabled for final renders. This also affects shadows casted by transparent shadows.

Render¶

Samples: The number of samples to use in the final render.

Shadows¶

Rays: Number of rays to trace for each light. Higher values reduces the noise caused by random shadow sampling.

Steps: Number of shadow map sample per shadow ray. Higher step count results in softer shadows but have a higher cost.

Volumetric Shadows

Approximate light absorption of the surrounding volume objects. This makes the volumes more opaque to light. This is a very computationally expensive option and has limitations.

Steps: Number of steps to compute volumetric shadowing.

Advanced¶

Light Threshold: Minimum light intensity for a light to contribute to the lighting. Used to compute the distance at which to cut-off lights influence. Lower values improve performance.
