Hi,

sure its possible.

Each .geo file has a LIGHT_ section and the

LIGHT_POSITION 0 0.20 -0.40 1.00 0

is the line for the sun position

FIRST and last number (0) are not important, but the middle 3 set the sun location

0.20 north-south direction
-0.40 east-west direction
1.00 hight

but if you change it, it maybe doesnt fit the shadow given in the phote sceneries
