Reflector

The Reflector extension empowers you to configure reflection settings on a mesh, enabling both planar reflections and bounce lighting effects:

Add Extension > Render > Reflector

Planar Reflection

This option enables a reflection plane, which renders the entire scene again from a mirrored perspective and mapped onto the surface. This creates a realistic reflection effect.

Planar Reflection settings

This only works on flat and even surfaces

Fresnel

The Fresnel value restricts the visibility of the reflection based on the viewing angle relative to the surface.

Example Material: Diffuse Color (0,0,0), Metalness 100%, Roughness 0% -- Fresnel 1,7x

Planar Bias

This value creates a small bias offset to avoid z-fighting and flickering in far distances

Planar Offset

The reflection axis is aligned with the origin of the 3D model object. When applying planar reflection, for example, on a cube, the reflection axis can be adjusted using the planar offset.

Planar Roughness Offset

The planar reflection is blurred based on the material's roughness. This behavior is not always desired and can be adjusted here without modifying the material itself.

Bounce Lights

With this option, it is possible for a light beam or laser to be reflected. This can be enabled separately for spotlights and lasers.

Bounce Light settings

This option creates an additional light source for each reflector. This can be very performance-intensive!

For bounce lights to work, the shadow quality must be set higher than Low! Also the Cast-Shadow option of the model itself must be active.

Multi-Bounces

Multiple Bounces are only possibe for Lasers (no projections). To enable this, select the Laser-Fixture and look for the child "Laser" object. Here you will find the properties "Max Reflection Bounces" and "Trace Reflections". These define when and how much bounces are supported. Max 4 are allowed.

Limitations

• Bounce lights do not trace shadows.

• Objects positioned between the light source and the mirror block the direct light cone but still emit a bounce light.

• Multi-bounces are only possible with lasers (beam only)

• This only works on flat surfaces
