I was holding off a bit till I got to painting, but I've not had the time to mess with it too much, so here is the chunk of designing the walls and detailing the floors.
To do the floor detail is really easy, get a ballpoint pen (Some people use a dead one, I like to see my lines and find it is easier when the ball still rolls) then have at it. This is really easy actually. If you want to roughen up your ground, you can use an aluminum foil ball as shown below.
I am doing the walls in a variety of techniques at once here, so bear with me. Sections 1 and 2 are both hewn rock walls, 3 and 4 are different types of cave walls.
Section 1 has blocks cut out like the floors are done, this creates an old block feeling which would be good for most dungeon style layouts. It is mildly time consuming but looks nice. Section 2 has blocks drawn in with a pen, this creates a new block wall style that would work well for a castle or an egyptian looking location. Section 3 is done by taking the knife at an angle and ripping chunks of foam out. It is fast easy, but does require a little bit of time to learn to do well, a few practice pieces will work well, try whatever tools you have around. Section 4 is done with a wire cutter, this would make nice ice or water worn cave.
I'm going to spend more time on 3 as it is what most of you have seen from me and seems to work best for Super Dungeon Explore (especially with Caverns of Roxor coming out soon) After cutting some chunks out with a knife, take your fingers and dig in with your nails pulling upwards, this makes a circular pocket pullout that works well, linking them together has a pleasing appearance.
Now, holding the knife perpendicular to the surface drag it across lightly, do this a bit till it starts to break apart. Then rub with your finger tip.
Lastly, section 1 and 3 have had a ball of aluminum foil rolled across them, this makes a nice rough surface that works well for drybrushing, to be honest, I don't like this appearance and rarely use it. However, it does work well and can create a nice appearance.
Once again, break out the pen and draw cracks onto section 1, this gives the stone character, try and be random. Evenly spaced is not random, have some clumps, have some clean sections, etc. When painting, weather accordingly.
Now, Section 2 is getting a special treatment. I have a Silhouette SD paper cutter which is essentially a printer with a knife blade. It cuts out paper for scrap booking and the like. I designed some wall patterns and fed them through the cutter, you could do this by hand also, hence the inclusion. As a point of interest, it took me 4 hours to do walls for a single tile using this technique, so migraine alert. It takes that long to do an entire caves walls.
Comparison with figure.
Till next time.
