I wanted to show some progress on the brick pieces.
I'm going to break the brick molds into two categories; above ground buildings and underground buildings. Above ground buildings would be houses, shops, train stations, apartment buildings and so forth. Underground buildings would be sewers, dungeons, cellars, prisons, asylums, subways, laboratories and anything else in an underground situation.
These two categories offer their own challenges. I'll cover the problems with above ground buildings on a new thread. For underground settings, the biggest problems were how to finish the tops of the walls and what kind of decorations to use. None of the decorations I've tried seemed to work. Pillars simply look out of place. I think it's because most underground brick settings do not have interesting architecture. If you think about it, how decorative would a sewer actually be? It's basically brick tunnels for sludge to flow through. The same goes for a cellar or prison. You simply have large vaulted areas to support the weight of the ground above.
All of the blocks you see here are test sculpts that will not appear on the final mold. They are inaccurate and have been worked over a few times to try different textures. I've cast a few hundred of these blocks to give me a good idea of what proportion of blocks would work best without having lots of a certain block left over. Using these test blocks, here's a few ideas that can be built with them.
I think I've solved the decoration problem by sticking to simple arches with recesses much like the gothic molds. The other decorative bit is a stepped base block to finish the bottoms of braces and recesses in a simple way. Since I wanted to give the feeling that you were underground, I've finished the tops of the main blocks with rubbles lined in brick. This will work nicely for ruins as well as giving that underground feel and add interest to what would be a fairly dull strip of hallway.
In case you are wondering, yes I intend to make the ruined blocks interlock just like the ruined blocks on mold #75. The ruined blocks you see here are tests and do not interlock accurately.
It's hard to see from the photos but the cracks between the bricks and some of the recessed areas are sand blasted so they will take stain. On all of these examples, I did not even look to see if the bricks were flipped the "right side up" so the bricks align. They're all just willy-nilly stacked together. What you see here includes three sizes of arches; a 1.5" low arch (1/2" thick), a 1" low arch for doorways (1/2" thick) and a 1/2" wide circle arch (1/4" thick). The 1/2" wide low arch will go on the above ground brick mold later on.
The basic principle is that you have arches in the wall with 1/4" thick recessed brick panels (textured on both sides). I was able to keep the gaps between the brick shallow enough so that this texture could be cast on its side. If you're wondering about the floor tiles, these are what the test tiles look like:
I'm still working with the texture on these. Getting this rock texture on all sides and keeping the tiles and exact size will be challenging, but I think I've figured out how to do it.
At this point, I'm starting the final sculpts for the underground brick blocks. However, I'm not going to make the final mold of them until I finish a couple of other groups of blocks including the above ground brick pieces and the sewer accessory. At that time I will choose which blocks go on which molds before making the final decision. This also gives me time to consider your suggestions for what the brick molds should include.
In a few days I'll start new threads for the above ground brick mold and the sewer accessory mold. I'll show you what I have for those and ask for suggestions at that time. I believe it will be a few months before I have these molds completed. New ideas happen all the time and I don't want to leave any important pieces out accidentally. I'm sure most of these will be finished by Gencon in August.
