I think I came up with an easy way to recreate "Fog of War" at the table.
So... I had an upcoming session where my players would be exploring a cave system with multiple tunnels, and the map I drew on Inkarnate ended up being relatively large (an A0 in total size printed into 8 A3 pieces).
I reaaally didn't want to cover everything up in black carbon paper like I usually do. Plus, it makes no sense. If you just lay pieces of paper and move them out of the way as they advance, they might see adjacent tunnels or caverns they're not suposed to see. And If you cover the tunnels individually... then you're already telling them where they are, and it's stupid.
Long story short, after a lot of thinking and searching online, I came up with the idea of painting 2mm A3 acrylic glass sheets with washable black paint (the kind toddlers use at the kindergarten). It darkens the acrylic glass enough to become opaque and have them guessing what lays underneath. You can easily find all of this online or at an arts & crafts shop. And I would recommend using a small paint roller for a homogeneous coating.
It works way better than I expected! Once the paint is dry it is consistent enough not to peel (more than one layer of coating possibly will, though), and very easy to wipe off. I gave my players baby wipes to not make a mess with water and sponges and the removal process is easy and clean. Also, once you're done, the rest rinses off super easily under the faucet.
I wanted to share in case anyone needed to come up with something similar.
I'm including pics of the testing I did previous to the session and the outcome. Apologies for the quality of my pics. I have a very shitty phone.
Edit: Are the pics showing?
