Hey all, kinda at my wits end, guess I don’t have much wit left.
I can’t even wrap my head about the lighting stuff. I’m trying to learn about light thru blocking light leaks.
- The course shows using floors to block the ceiling but this doesnt work for me.
a) the floors dont block light and they are transparent from underneath
b) I duplicated SM_floor and inverted the normal using modeling plugin which makes it visible from below but it still transmit lights.
c) I read things need to be 10cm+ thick for lument but I cant even figure out how to change thickness!
Please help me understand 1) how to change thickness 2) how to make the sm_floor block light like I expect and allow me to make a perfectly dark room. 2b) is there a way to do this by alltering the mesh properties or is the only ways to use “fixer” meshes either visible to player or light blocking geometries not visible to player?
I am a decent coder and i think thats working against me here because i am constnatly frustrated by how hard even “simple” things are in UE… 
please help
