Hills — the search for perfection continues

I've started another couple of hills, with the lessons of the first lot in mind.

In the foreground is a long (about 800–900mm) rocky ridge. It's got a bunch of flat spaces and ledges in amongst the general rockiness, as it's supposed to be impassable to vehicles, but climbable by foot troops with appropriate climbing skills.

The top half is slathered with my texture paint, which I've now remembered to actually add paint to. It's a mix of acrylic filler, paint and sand, painted and dabbed on to the foam, and it fills small seams and leaves a good ground texture. It's only on the top half at the moment, because I've just added a whole lot of clutter and rubble around the foot of the hill, and the acrylic caulk I'm using as glue (Selleys No More Gaps) isn't set yet.

I tried gluing sections of this one with construction glue (Selleys No More Nails), and though it creates a very strong bond when it eventually sets, it takes a looooooong time to set. Especially between layers of foam; it's not really ideal for use in that sort of environment I think. There are probably more specialised adhesives that would work better, but the acrylic caulk does a good enough job for my purposes, and is a lot cheaper.

The thing in the background that looks like a plate full of tofu slabs is a stepped ziggurat-style hill in its early stages of construction. When the caulk on that is set, I'll start carving and chipping it into more rounded hill shapes. It's going to be a lot less naturalistic-looking than any that I've done as yet, as it's supposed to be climbable all round, so it needs to be stepped all round so that figures can stand on it.

Yet Another Hill

 I got a cheap 30-watt foam-cutting hot wand from China a few days ago, and tried it out by carving up a foam off-cut into another hill. ...
