Daylight system objects are not creatable by MAXScript.
A Daylight system is comprised of a Compass Helper object and an Assembly containing an IES_Sun and an IES_Sky object using a DaylightAssemblyHead. The Light objects can be accessed as properties of the Assembly Head.
The Assembly's transform is controlled by a set of controllers, which are sub-controllers of a Sunlight_Driven_Controller
controller. To access the controller, create a Daylight system using the Create>Systems tab in the UI and use:
$Daylight001.controller
Controller:Sunlight_Driven_Controller
Prior to 3ds Max 2022 this class was called Sunlight_Slave_Controller
.
<Sunlight_Driven_Controller>.solar_time Float -- subAnim[3]
The solar time expressed as an integer value of seconds since midnight. To calculate the hours, minutes and seconds, you can use the following function:
SCRIPT:
fn TimeFromSolarTime dlSystem = ( local solar_time = dlSystem.controller.solar_time.controller.value local hrs = int solar_time-- full hours in the solar_time value local min = int((solar_time-hrs)*60.0)-- full minutes in the difference between the full time and the full hours local sec = int((solar_time-hrs-min/60.0)*3600+ 0.5)-- full seconds in the rest of the value #(hrs,min,sec)-- return the result as a 3 elementsarray ) TimeFromSolarTime $Daylight001
<Sunlight_Driven_Controller>.solar_date Float -- subAnim[4]
The solar date represents the days offset fromJune 21 st , the date of the Summer Solstice. You should access the .solar_date.controller.value to get the correct value as a Float.
<Sunlight_Driven_Controller>.latitude Float -- subAnim[5]
The viewer location's latitude.
<Sunlight_Driven_Controller>.longitude Float -- subAnim[6]
The viewer location's longitude.
<Sunlight_Driven_Controller>.orbital_scale Float -- subAnim[7]
The Orbital scale controls the distance of the Assembly from the Compass Helper.
<Sunlight_Driven_Controller>.sky_cover Float -- subAnim[8]
The Sky cover value, 0.0 means Clear, 1.0 means Cloudy.
<Sunlight_Driven_Controller>.manual_position Transform -- subAnim[9]
Contains a PRS Controller to hold the manual transforms.
<Sunlight_Driven_Controller>.manual_intensity Float -- subAnim[10]
Set the intensity when in manual mode.
