Illumination rendering method and system, electronic equipment and storage medium

The invention relates to the field of image display, and particularly discloses an illumination rendering method and system, electronic equipment and a storage medium. The method comprises the following steps: dynamically determining a to-be-updated probe corresponding to a target rendering area in a virtual scene; wherein the to-be-updated probe is a probe called in the rendering process of the target rendering area; and according to the probe calling mode of the to-be-updated probe, performing updating processing on the to-be-updated probe so as to perform illumination rendering operation according to the updated illumination data in the to-be-updated probe. In the mode, the updating mode of the probe can be determined according to the calling mode of the probe, so that on-demand updating of the probe can be realized, different updating modes can be conveniently configured for different probes, the operation overhead of probe updating and the requirement of scene illumination rendering are considered, and a
