Washed UP, 1490 Doom diorama board

I finished building up the EVA foam and did a first detail pass by cutting diagonal and perpendicular across the foam stacks to emulate fault lines. This created a grid like pattern, which I attacked with tweezers adding depth and texture. The foam was sealed with a heat gun. I used foam clay to transition the EVA foam into the board, after heat sealing the foam the clay adhered to it far better than before.

Super glue releases hydrogen cyanide when heated, the surface of the foam should not reach temperatures high enough for this to be an issue though did this outdoors, used a respirator and left it for an hour to off gas.

Next I started on the fishing settlement, these platforms that will form the bulk of the playable surface of the board and instantly provide a sense of scale.

As the rock formations are built up I’m paying particular attention to the height, in 1490 Doom equipment allows characters to clime different heights. I’m creating levels at specific heights to create different routes to navigate the board.

These local friendly cultists offered to demonstrate my process. Cuddles on the right had no equipment so climbed to the lower ledge at 3″. Bubbles on the left had a ladder in his equipment so was able to reach the 4″ ledge. Fluffy in the middle used a grappling hook to climb straight to the top ledge at 6″. In the finished piece the ledges will be identified with grass tufts to aid gameplay and add more more contrast.

Despite covering the board with 20ft skulls I don’t want them to be a prominent part off the finished piece. They are recessed in to caves and overhangs in create more interest (and hide the heinous mould lines).

I haven’t used foam clay before but as this will be a 600mm diameter diorama I want to keep the weight to a minimum.

I did a small section to test adhesion and detail retention. The foam clay is a pleasure to work, with no mess or strange smells. I replicated the fractured texture of the skull which is quite convincing when cured.

I thought the clay would bond well to the EVA foam but it just slides off. I’m going to try heat sealing the foam and a coat of modge podge next. Once cured the foam clay binds well with superglue.

The main issue I found was that I couldn’t get a smooth transition from the foam clay to other materials (plywood, foam and smooth plastic) as I would with Milliput or Das clay. I think this can be mitigated with more strategic sculpting but I will also try, cutting and sanding the edges after securing with more superglue.

After deliberating for far to long how I would cut a perfect circle without access to my workshop, in the end I just buzzed it out with a jigsaw.

For the initial shapes I cut/ripped 10mm EVA (craft foam) floor tiles to shape and used bamboo skewers to hold in place before locking them in place with liquid super glue. EVA foam loves superglue! this allowed my to secure the skulls which were again roughly cut to shape. The scale breaking sections of the playmobile pirate ship were removed with a rotary tool and ball gouge.

Most of this will be covered with other material in later steps so its just about roughing in the shapes at this stage.
