Hirst Arts III: Design of Modular Dungeon v1

May 14, 2011

We finally decided to pick up two Hirst Arts molds and try building a dungeon.

First up we needed to gather our supplies. And then prepare for the eventual mad construction by casting a lot of blocks. We went to a builder supply and bought dental plaster. Our experience with plaster of paris is that it’s softer and takes longer to set, which offsets the small extra cost of the dental plaster. Ours was less than $50 for a 100 lb bag. If you go to the hardware store you pay about the same amount per pound for dental plaster.

The next step is to plan out what your dungeon will look like. A modular dungeon works best, since you can change the configuration to whatever you want at the time.

The Hirst Arts website has a tutorial on how to make the dungeon pieces. You should check it out, man. What they don’t tell you is that you’ll want a base that’s more rigid and durable than cereal box card. This is because you might pick up the dungeon block by a corner, which means all the weight is supported by a few weak glue joints between blocks. Better to have the weight supported by the base. For that base, we chose 1/8″ thick plywood. You can get it from the hardware store for a tiny fraction of the price of balsa tiles at a craft store. Ours cost $4 for 24 sq feet.

The next part is line-of-sight. For us, it was very important that people sitting next to the table be able to see their figurines in the dungeon without standing up. That meant the standard 1/2″ wall height (two standard bricks high) was too much. We’re doing just one brick high (1/4″). The floor bricks are 1/8″, walls are 1/4″, and lengths are all in 1″ and occasionally 3/4″ for special pieces. So everything fits together very well!

Next we need to actually set out the floorplan.

The website tutorial has three floor bricks across for a standard hallway. That’s 3″. But if you make a hallway piece, you’ll have a wall sitting on top the outside floor bricks. So you have a center row of floor, and a pair of half-inch floor spaces on either side of it. Effectively the hallway is 2″ across. But in reality, you can’t fit two figures in it side by side. So instead we’re counting any half-bricks as non-walkable space. So a dungeon block 3″ across actually only has 1″ of walkable space, and at 25mm scale is 5′ across. This will waste some table space, but it’ll be much easier to use.

We also need intersections. We’ll need a 90-degree corner, a T, and a four-way. We’re making the rooms modular as well. That is, instead of a whole room, we have room pieces. For that purpose we need tiles that have some number of open corners. Check out this diagram:

(Note: this is actually an old unposted post that I edited to reflect what we actually did. We have a second-generation tile configuration and I like it better, but we actually did make the set described here. I’ll update this post with pictures when I take them. I’ll take pictures of the Version 2 set at the same time and make a new post about it.)
