Add a Spot Light
Spot Light
Method #
Add a Spot Light node into the scene.
Attach the Target Node input to any object, to have the light track that object.
All nodes connected to this node are treated as if flowing to the parent node, and inherits any transformation changes along the chain.
Parameters
Parameter Details Position X The objects position along the local x-axis.
Position Y The objects position along the local y-axis.
Position Z The objects position along the local z-axis.
Rotation Heading The objects rotation around the local y-axis.
Rotation Pitch The objects rotation around the local x-axis.
Rotation Bank The objects rotation around the local z-axis.
Scale X The objects scale along the local x-axis.
Scale Y The objects scale along the local x-axis.
Scale Z The objects scale along the local x-axis.
Control the inheritance of the transforms from the parent.
Parameter Details Position Toggle inheritance of the Position from the parent.
Rotation Toggle inheritance of the Rotation from the parent.
Scale Toggle inheritance of the Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.
These properties control the core behaviours of the node.
Parameter Details Colour The colour of the light.
Light Cone Angle Change the size of the area the light covers.
Light Inner Cone Angle Change the inner angle of the lights focus.
Brightness How bright the light is.
Scattering Intensity How much the light is scattered by the light, creating a simple fog around it.
Falloff Mode Change how the light falloff is calculated.
- Inner / Outer Radius (Legacy) : light falloff is calculated between the inner and outer radii.
- Inv-Squared Distance (Physical) : the light falloff is calculated based on a physically accurate system.
Attenuation Distance Maximum distance the light reaches.
Falloff Power Change how strong the falloff for the light is between the Inner Attenuation Distance and the Attenuation Distance.
Penumbra Falloff Power How quickly the edges of the spotlight falloff.
Apply Specular Enable/Disable specular lighting.
Apply Diffuse Enable/disable diffuse lighting.
Projection Image Select an image to be projected from the light.
Projection Map Amount How much the image affects the projection.
IES Profile IES light profiles are published lighting profiles from manufacturers that show the lighting energy and patterns produced by their lighting systems. Notch is able to use these profiles to accurately replicate real-world lighting in its environments. A good resource site for these profiles can be found here.
Show Light Cone Show a cone in the scene to represent the lights current position and rotation.
Parameter Details Casts Shadows Toggle whether baked shadows are applied to the objects lit by the light node.
Shadow Softness Change how much softness is applied to the shadow edges.
Z Bias Increasing Z bias will improve the accuracy of grounding objects to their shadows.
