Disable Shadow Map Updates (2023.2)
We added setShadowMapUpdates(bool) and getShadowMapUpdates(). To prevent any shadow maps from updating, use setShadowMapUpdates(false). Lights created while the update is set to false will also be included and their shadow maps will not update. Re-enabling updates will trigger a render, updating all shadow maps.
When a new scene is created, this command is reset to true and shadow maps are updated.
