Introduction

Shadow rendering, an element of global illumination, applies a shadow effect to solid objects within the scene.

To achieve this effect, a shadow rendering technique known as the shadow map algorithm is employed. Using this method necessitates a certain allocation of GPU memory and requires a dedicated rendering pass to generate the shadow map. To optimize performance, the system accommodates up to four shadow maps.

Viewports with identical visibility settings across all parts are merged to use a single shadow map, so an unlimited number of viewports can be used. Shadow effects work for a maximum of four viewports if each has a distinct visibility configuration.

Shadow rendering uses a single directional light source, specifically the one with the highest intensity value.

To toggle shadow rendering, from the menu bar select View > Shadow.
