Mask Mode?

[Iceman]

It no longer appears that I can hide and reveal a map. I have clicked on MASK MODE and it hides the entire map from the players. But previously I would use ALT key to drag the mouse around and reveal part of the map. While I can see the blue area I draw on my GM map nothing is revealed to my players. This is the Worm Nursery map from Out of the Abyss which I purchased here on FG. Whats the new secret to revealing part of this map like I used to be able to do?

Interestingly I found a second copy of the map, the GM version of the same map. The GM version WILL allow me to reveal parts of the map as I desire. So the problem is solved for tonights game. However I am curious as to why the Players map does not allow a mask reveal even when I UNLOCK the padlock? Is this something inherent to the module or am I missing something about masking and unmasking now?
Thanks for any clarifications.

You can still use the mask the same way as in Classic, what the players see will depend on whether you have lighting enabled and line of sight. The fact that it works on the DM map (which has neither LOS or lighting) suggests that you haven’t sorted out the players map and/or their tokens to work with lighting.

With line of sight and lighting enabled there’s really no need for mask mode, but if you prefer masking then I’d suggest you turn off lighting.
