光照探头平面#
A light probe plane records the light incoming from a single direction for all visible points on a plane. The specular reflection direction is the only one currently available.
This type of light probe is suited to smooth planar surfaces.
Each visible planar light probe increases the render time as the scene needs to be rendered for each of them.
Light probe planes only work when the ray tracing method is set to Screen-Trace.
When enabled, they accelerate the tracing process and complete the missing data from the screen space ray tracing.
Note
Reflections and volumetrics are not supported inside Light probe planes.
放置#
If Backface Culling is not enabled, snapping the light probe plane to the planar surface will effectively capture the underside of the surface.
You can manually move the light probe plane above the surface enough for it to not appear in the capture. Alternatively you can disable the light probe visibility in the object visibility panel.
属性#
参考
- 面板:
- 距离
A probe object only influences the lighting of surfaces inside its influence zone. This influence zone is defined by the distance parameter and the object's scale.
For light probe planes, the influence distance is the distance from the plane. Only surfaces whose normals are aligned with the Reflection Plane will receive the captured reflection.
捕获#
- 钳制偏移
Define how far below the plane the near clip is when capturing the scene. Increasing this can fix reflection contact problems.
