Hey! I'm trying to replicate this monster in roll20 (a monster that can make "invisible" walls and is "invisible" because they are both pure white in a demiplane which is pure white), but when I use Dynamic Lighting, the shadows of things out of my player's (in this case a test dummy) line of sight reveal where the walls are. The only solution I've thought of is making the entire map black and doing that instead, maybe requesting my players use a negative filter on their screen, but I'd hope to ask here first in case there was a more elegant solution. So, can I change shadows to be white (or no color at all)?
