Here’s my tomb
I made a tri-planar material for my walls (Iwatched a youtube tutorial on how to do it here: https://www.youtube.com/watch?v=yP4Yhlztqw0). I used it on the floors and roof for now too just to get a feel. There seems to light entering around the door frame on the outer edge which I guess I’ll have to work out how to fix at some point.
