Import Light Variable VEX node

Imports the value of the specified variable from a light shader and stores it in “var”.

See also: Global Variables, Import Displacement Variable, Import Surface Variable, Illuminance Loop

This operator imports the value of the specified variable from a light shader and stores it in “var”. “found” is set to 1 if the variable is found, otherwise it is set to 0.

If the variable being imported is not found, the value connected to the “default” input is assigned to the output value. If no input is connected to “default”, the value is initialized to 0.

This function is only valid inside an illuminance loop.
