Hey everyone! I'm pretty new to Dark Radiant, and I'm building a "test mission" for myself, and I have two questions for you guys. 1) How do I create a briefing for my mission? I was already able to create my objectives, readables, etc., but a briefing eluded me so far. 2) On my map, a buggy shadow triangle thingy is forming on the ceiling of one of the rooms, and I can't figure out the reason behind it. I tried changing the ceiling's texture and the location of the light source but the triangle stayed. Anyone experienced something similar? Well, thanks in advance for the help!
