Sampling panel
Viewport subtab
| Entry | What it does |
|---|---|
| Samples | The number of samples when rendering in the viewport. |
| Temporal Projection | Denoise image using a method called temporal reprojection. This method can leave some ghosting. |
| Jittered Shadows | Enables jittered soft shadows in the viewport, improving shadow realism by introducing subtle randomness to shadow sampling. This helps reduce banding and aliasing artifacts in dynamic lighting setups. Note: Jittered shadows are always enabled for final renders. This is an viewport override for performance. |

| Volume subtab | Direct Light: The maximum value for lights contribution in volumes. A value of zero disables this feature. Higher values will be scaled down to avoid too much noise and slow convergence at the cost of accuracy. Used by light objects. · Indirect Light: The maximum value for indirect lighting in volumes. A value of zero disables this feature. Higher values will be scaled down to avoid too much noise and slow convergence at the cost of accuracy. Used by light-probes. |
