Color Light from Control Point

Two lights with pre-defined colours.

The Template:AS add creates four "particle lights". Each light can use a predefined colour or sample dynamically from the world, and can be omnidirectional or a spotlight.

Properties

Clamp Minimum Light Value to Initial Color

Clamp Maximum Light Value to Initial Color

Prevents particles from going under/over their initial colour value. If the minimum value is not clamped, particles that are not lit by this operator will be pitch black.

Todo: See $halflambert.

Initial Color Bias

Whether the operator's lights should replace or add to particles' base colours. It appears that this property was supposed to be a factor, but it actually behaves like a boolean.

Light settings

There are four lights. Each one has the following properties:

0% Distance

50% Distance

How many units away from its origin the light should cast.

Color

The RGB + brightness/alpha value for the light. Brightness is ignored.

Control Point

Control Point Offset

The control point at which the light will be created, and an optional offset from it.

Confirm:Offset is local to the target CP

.

Direction

If this is a spotlight, this normalised vector is translated into a direction to point in. 1 0 0 means "point down the X axis".

Dynamic Light

Whether the light's colour should be sampled from the world or fixed to the value of Color (see above).

Spot Inner Cone

Spot Outer Cone

If this is a spotlight, this float defines the width of the beam in degrees. The widest possible Outer Cone is 80.

Bug:Inner Cone is nonfunctional. Set it to 0 to prevent any confusion.  [todo tested in?]

Type

0 = omnidirectional point, 1 = spotlight.
