I am trying to figure our a way to have some dynamic lighting lines block movement and some not block movement, while others block site and others still don't. I have lines that don't block line of sight but still block movement, lines that block both, but not lines that block sight but can be moved through. As an example this is what I am looking for. Block sight but not movement: The Forest. Block movement but not sight: The Cliff. Block Sight and Movement: The Wall. I use Doorknocker if that helps. I want the players to be able to waltz through the forest and not be able to see if there are traps/monsters lurking, but their movement not be impeded by anything other than caution. But when they come to the cliff I don't want them just zooming over it. Instead they will make climbing rolls and I will move them to the next level of the cliff, etc.
