Hi (first time poster), So I've been playing a D&D campaign on roll20 and have been loving it. I also really like the new vision feature. However, I'm having trouble efficiently changing vision based on where characters are. For example, when a character is behind a wall, the wall blocks his line of sight. However, once the character climbs on top of the wall, he can see pass the wall. In my campaign settings, once the character is on the wall, his vision is still blocked by the wall. The wall is a square wide and has vision blocking traced around it. Any suggestions.?
