I am building a dungeon for my upcoming game tomorrow, and I seem to have hit some sort of bug. I drew careful lines along the cave walls to limit sight, added them to the lighting layer, and then added torches. I had my wife join on her account (not a gm acct) and she could see through most of the walls. To help you help me, here is what I have checked: I am using firefox I am only using dynamic lighting, not legacy Her token is controlled by her only, and has vision enabled. There are torches throughout the dungeon emitting 10 feet bright 10 feet low light. She can see them through some walls, but others it is blocking as intended Her token is on the token layer, the lighting is on the lighting layer (as are the walls) It is set to permanent darkness, so as she leaves one part of a cave, the part behind her disappears. Page cell width is 1 Restrict movement is on. There is a door she cannot move through until its open. But she can see through it. I have heard there is some sort of limit to walls, but she can see through almost every wall save for maybe 15%. If that is the case, then the wall limit would have to be terribly small. I didnt draw the entire cave walls zoomed out, I drew them in segments, not too long, not too short. I have tried adding new walls just to see if I can block her vision, and no new walls seem to be working either
