ok, simfox, the sjadow generating light, where can I find it?, in the Customize-View potr configuration....., or in the folder of cameras and lights? please told me how can I do.
I think I am going to devide the model in two parts, the base and the top to fix the light rig error, because when I merge the light rig medium, huge or big, the model see with a lot of light like the last render, and when I click south, nort, west and east the building do not move, I only can see the souht in the renders.
