The [ReflectionProbe] is used to create high-quality reflections at the cost of performance. It can be combined with [VoxelGI]s and Screen Space Reflections to achieve high quality reflections. [ReflectionProbe]s render all objects within their [member cull_mask], so updating them can be quite expensive. It is best to update them once with the important static objects and then leave them.
If [code]true[/code], enables box projection. This makes reflections look more correct in rectangle-shaped rooms by offsetting the reflection center depending on the camera's location.
Sets the cull mask which determines what objects are drawn by this probe. Every [VisualInstance3D] with a layer included in this cull mask will be rendered by the probe. It is best to only include large objects which are likely to take up a lot of space in the reflection in order to save on rendering cost.
If [code]true[/code], computes shadows in the reflection probe. This makes the reflection probe slower to render; you may want to disable this if using the [constant UPDATE_ALWAYS] [member update_mode].
The size of the reflection probe. The larger the extents, the more space covered by the probe, which will lower the perceived resolution. It is best to keep the extents only as large as you need them.
Update the probe once on the next frame. The corresponding radiance map will be generated over the following six frames. This is slower to update than [constant UPDATE_ALWAYS] but can result in higher quality reflections.
Update the probe every frame. This is needed when you want to capture dynamic objects. However, it results in an increased render time. Use [constant UPDATE_ONCE] whenever possible.
