location=x,y,z
orientation=x,y,z
pointat=x,y,z

These parameters specify where the light is located in Mirage space, represented with Cartesian coordinates x, y, and z positioned at the location of the light.

Lights can be reoriented in space by specifying components of a quaternion for the orientation parameter.

color=[Color]

The color of the light can also be set in the form of a hexadecimal string #RRGGBB, where RR, GG, and BB are hexadecimal values of red, green and blue between 0 and 255.

attenuateconst=[Float]
attenuatelinear=[Float]
attenuatequad=[Float]
attenuaterange=[Float]

These parameters specify how the light attenuates (fades over distance.)

name=[String]

The internal representation of Mirage environments assigns a name to each light. This can be changed using the name parameter here.
