Hi guys,

Looking for some sculpting tips. I 3D printed a piece of Necron terrain, and I want to make it look like it emerged from under the earth, shattering the rock layer above it as it broke through the surface.

How would you visualize that? I am thinking sorta concentric rings, like a gunshot through glass. edit Oooh, or a sub surfacing under ice!

The real problem - how would you sculpt it? It's a big print, so I was going to use Sculpey and bake it, but no clue how to avoid fingerprints, and how to get the sharp corners you would expect on broken stone.

Thanks!

Why not cut the sharp "rock" features out of foam?
Imho, it would be waste of time to sculpt strait, clean rocks. Especially in large scale!

I would ether cut them from foam, or cast rough surface with plaster of paris into a dirt mold and break that with a hammer when dry.

For sculpting.
To keep fingerprints out when sculpting just wear latex gloves or those latex finger cots.
Or use a burnishing tool or a rubber sculpting tool to smooth-out the surface.

Depending on the sculpting medium! different solvents aid in smoothing out the surface detail. Like water for clay or mineral spirits for oil based scupley that does not dry out.
However I am not a sculptor, I just know that solvents aid with smoothing, however I don't know what solvents in what ratios for what materials, sorry

I like the plaster of paris idea quite a bit, and I already have a ton. Thanks!

What kind of foam are you thinking?

KEEP in mind!
That I have not tried to cast plaster into the dirt mold! I just think that it should work, unless you mix it very liquidy.
I just wouldn't want to spend the time in making a mold for one cast piece that will be broken up anyways. If packed dirt in the backyard works, then cool! Like the old school sand metal casting.

Like, if it works for metal and glass, should work for plaster
SHOULD

Have you checked out the rock effects possible with cork tiles? You should be able to tear up cork and layer it to look like different strata being displaced.

Please excuse any spelling errors. I use a tablet frequently and software keyboards are a pain!

Have you looked into using cork board? it beaks up into a great rock looking texture!

This stuff works great for me. https://smile.amazon.com/gp/product/B000V4OLP0/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1

I just bought some cork sheeting, and will try both the plaster and cork to see which looks better.

Thanks for the advice, all.

Slate roof tiles and a hammer?

Only half joking. Get some real rock on the brittle side and take a wack at it.

For broken stone, you could just fill a disposable Tupperware with plaster. Once it's set, go to town with the hammer.

Another vote for the cork tiles. Also, lawn and garden chipped bark can be used.
Hope we get a share when you finish. Love your idea.

I poured some plaster of paris onto an old wrinkled shopping bag, let it dry, and then smashed it with a hammer. It didn't work as well as I had hoped - there was not enough texture on the top/bottom. It would work great for basing minis, though, because the chunks would be a lot smaller and the "flatness" less apparent.

On the plus side, I had all the stuff in the house, and it only cost a few cents of mats and few minutes of time, so... eh.

Still waiting for the cork tile I ordered to arrive. I might venture out and look for slate.

Thanks again for the ideas.

The benefit of slate is that its.actually a.rock with rock like properties. The downside is that it's a rock and in my experience a pain in the bum to keep on the base.as its heavy and needs a.lot of sticking down. Also if you want to have anything other than a solid planted 2 foot stance on the model, then pinning needs a proper power tool, compared to a normal.pin vice to pin into cork.

Just as a heads up, I haven't abandoned this idea - in an act most unusual for me, I have followed through and am now painting the basing. I will be posting pictures soon, maybe even today.

I wound up going with cork because it was cheap and I didn't have to leave the house; I just got some off Amazon.

I will try slate at some point in the new future, though. I already have some very small slate chips I have used as basing, just nothing this big (bigger than a knight base, I think).

I wound up finishing it and did a Showcase thread.

Here are the base pics:

Spoiler:




I suspect a better painter could have done better with it, and even though it's not exactly what I was going for, it came out kinda neat anyway.

I will try again at some point with actual slate.

Thank you again for all the advice!

That is very nice! Absolutely gets the message across. Thanks for the follow up picks, and congrats on some nice terrain!
