Altho it is most likely due o a bug, and might get fixed. However, as it is right now, you can create walls that stop token movement, but doesn't stop line of sight. And its really simple to set up. As the I was testing the new lightning system I had to try out its quirks and most people probably remember how buggy the old system was when it came to circles, naturally I had to see if the new system in any way adress this. The answer is that it just completely ignores circles. What doesn't ignore circles however is the collision while moving around. Which leads to the following. <a href="https://i.imgur.com/rJ9t04w.gifv" rel="nofollow">https://i.imgur.com/rJ9t04w.gifv</a> ...windows! This glitch is already discovered and reported in the dynamic lightning thread. It might get fixed, it might not. It might be a hardware specific bug as well and you might not get the same results as me. Either way, I think its neat.
