I use unreal engine 4.16.
I want to have a realistic shadow based on the geographical position (longitude and latitude) of a building, its orientation (relative to the north), and the date and time. How to do ? Thank you for your help.
Turn the math behind these spread sheets into a blueprint.
I’m currently working on this myself, not finished quite yet.
this seems to be very hard, thanks a lot.
From now, there is no plugin ?
perhap, it is possible to use xls or csv file in unreal ?
in unreal : you select location , date and time
unreal go to xls to make calculations
and return sun position (elevation and azimut)
Depending on your exact requirements you can pull fbx data from say a 3dsmax daylight system and drive the sun position by a umg slider. I’ve done this for a few things… Its a fairly simple work around if say you want daylight data for one day between two times.
i want to :
design a house with a good north orientation
set the latitude and longitude of the house (variables in a blueprint)
interior lighmapping with artificials lights
have a menu with 3 sliders :
one for the date, from January 1th to December 31th)
an another for the time of the day ( 00:00 to 24:00)
a third for Time zone
package for windows 64 bytes
use of the 3 sliders
my calculations in the blueprint with
the result : Elevation and azimut of the sun
to have good position for the lens flare
and good shadows on the ground and through the windows
One more thing :
I have bought the plugin Ultra dynamic Sky
if it is possible, the choice with a check box to have or not clouds
