Here’s another experiment Tracked Light Test - YouTube this time I’ve put a tracker on a flashlight, then did some filming in a dark room with that as the only light source. This is very basic with no shadows or bounced light, but still looks pretty good. Updates (the “lighting test map”) are on github GitHub - MiloMindbender/GadgetTest: Test of virtual sets and tracked cameras the lighting test map uses special 1 for the camera and special 2 for the flashlight.
This uses a standard LED flashlight in the real world and a “spotlight” in unreal as the tracked light. I also tried using a small photo 14cm x 9cm photo light panel as a light source and a “rect light” in unreal, but this didn’t look so good because the light panel generates a very wide diffuse beam which lights the area too well. The flashlight gave a better beam of light so you could see it moving around.
I need to work out how to setup shadow catcher planes so Gadget can cast shadows on the floor and walls. Also need to figure out how to make the in-game light simulate light bouncing off the walls and floor so the self-shadows on Gadget aren’t completely black.
Anyone got advice on how to do it?
