I’m trying to make a simple demo to visualize floors of 3-story building.
I have a level blueprint to lift up the roof of 3rd floor to peek into the 3rd floor while running game.
I want to use static lighting for performance reason, and keep all the shadow baked even when I open the roof.
I managed to sort of realizing this by keeping the roof’s mobility “Static” and build light, and switch the roof’s mobility to “Movable” right before Play.
However once I rebuild the light, the roof is no longer casting shadow under my static light, so the sun light brightly lit up the floor, whereas I want to show my static spotlight illuminating the interior.
I looked at some documents, including the following, I’m probably overlooking a simple option to let dynamic objects cast static shadows under static lights, but have not got any luck so far.
The following video illustrate what I’m trying to do.
I appreciate your help in advance.
