ReflectionProbe¶
Inherits: VisualInstance3D < Node3D < Node < Object
Captures its surroundings to create fast, accurate reflections from a given point.
Description¶
Captures its surroundings as a cubemap, and stores versions of it with increasing levels of blur to simulate different material roughnesses.
The ReflectionProbe is used to create high-quality reflections at a low performance cost (when update_mode is UPDATE_ONCE). ReflectionProbes can be blended together and with the rest of the scene smoothly. ReflectionProbes can also be combined with VoxelGI, SDFGI (Environment.sdfgi_enabled) and screen-space reflections (Environment.ssr_enabled) to get more accurate reflections in specific areas. ReflectionProbes render all objects within their 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 as-is.
Note: Unlike VoxelGI and SDFGI, ReflectionProbes only source their environment from a WorldEnvironment node. If you specify an Environment resource within a Camera3D node, it will be ignored by the ReflectionProbe. This can lead to incorrect lighting within the ReflectionProbe.
Note: Reflection probes are only supported in the Forward+ and Mobile rendering methods, not Compatibility. When using the Mobile rendering method, only 8 reflection probes can be displayed on each mesh resource. Attempting to display more than 8 reflection probes on a single mesh resource will result in reflection probes flickering in and out as the camera moves.
Note: When using the Mobile rendering method, reflection probes will only correctly affect meshes whose visibility AABB intersects with the reflection probe's AABB. If using a shader to deform the mesh in a way that makes it go outside its AABB, GeometryInstance3D.extra_cull_margin must be increased on the mesh. Otherwise, the reflection probe may not be visible on the mesh.
