How do I make point lights actually only light up at night? I've seen this in a few maps, so how do you do this?
This is a Torque3D thing. Somebody on their forum posted a script which Ouerbacker used on its map (I used it too on my VR_City map). If you check in the files of my map you will see a 'server' folder with some scripts: You can basically copy that 'server' folder to your level. Then, all the lights you want to light-up at night must be placed inside a group (in the scene-tree) called 'dynamicLights'. That's it. You may need to edit the 'dynamicLights.cs' file with notepad to adjust when the lights actually turns on and off.
