Mapas cúbicos de reflexión#
Specular Indirect Lighting is stored in an array of cubemaps. These are defined by the Reflection Cubemap objects. They specify where to sample the scene’s lighting and where to apply it.

Screen Space Reflections are much more precise than reflection cubemaps. If enabled, they have priority and cubemaps are used as a fall back if a ray misses.
Cuando la oclusión ambiental se encontrara activa, se aplicará de una forma físicamente plausible a la iluminación especular indirecta.
Nota
The cube probes are encoded into tetrahedral maps. Some distortions may occur on the negative Z hemisphere. Those are more visible with higher roughness values.
Fundido#
The lighting values from a Reflection Cubemap will fade outwards until the volume bounds are reached. They will fade into the world’s lighting or another Reflection Cubemap’s lighting. If multiple Reflection Cubemaps overlap, smaller (in volume) ones will always have more priority. If an object is not inside any Reflection Cubemap influence, or if the indirect lighting has not been baked, the world’s cubemap will be used to shade it.

- Distancia
A probe object only influences the lighting of nearby surfaces. This influence zone is defined by the Distance parameter and object scaling. The influence distance varies is a bit, depending on the probe type.
For Reflection Cubemaps the influence volume can either be a box or a sphere centered on the probe’s origin.
- Decaimiento
Porcentaje de la distancia de influencia durante el que la influencia de una sonda decaerá de forma lineal.
- Intensidad
Factor de intensidad de la iluminación registrada. Cuando este valor sea distinto a 1.0 el comportamiento no será físicamente correcto. Usarlo para efectuar retoques o con propósitos artísticos.
- Recorte
Define the near and far clip distances when capturing the scene.
- Colección de visibilidad
Sometimes, it is useful to limit which objects appear in the light probe’s captured lighting. For instance, an object that is too close to a capture point might be better excluded. This is what the visibility collection does. Only objects that are in this collection will be visible when this probe will capture the scene.
There is also an option to invert this behavior and effectively hide the objects inside this collection.
Nota
This is only a filtering option. That means if an object is not visible at render time it won’t be visible during the probe render.
Paralaje personalizado#

- Panel:
By default, the influence volume is also the parallax volume. The parallax volume is a volume on which is projected the recorded lighting. It should roughly fit it surrounding area. In some cases it may be better to adjust the parallax volume without touching the influence parameters. In this case, just enable the Custom Parallax and change the shape and distance of the parallax volume independently.
