### Remarks

The progress can be monitored via [Lightmapping.isRunning](/engine/6000.0/script-reference/unityeditor/lightmapping/isrunning.md) property. [Lightmapping.bakeStarted](/engine/6000.0/script-reference/unityeditor/lightmapping/bakestarted.md) will be called when the bake starts, and [Lightmapping.bakeCompleted](/engine/6000.0/script-reference/unityeditor/lightmapping/bakecompleted.md) when it is done.

Only works in [Lightmapping.GIWorkflowMode.OnDemand](/engine/6000.0/script-reference/unityeditor/lightmapping/giworkflowmode/ondemand.md) mode.

For synchronous bakes see [Lightmapping.Bake](/engine/6000.0/script-reference/unityeditor/lightmapping/bake.md).
