Cracking Shaders

[dandelO]

I thought these might have been ready earlier tonight but testing a blend of two different scales of these cracks gave me a strange result(a big black shadow, being cast by nothing.) and I had to rework some things. I've fixed that now. Should have these done by tomorrow, if not tonight.*

They're by no means complicated function node work, like I've seen some of you mathematicians do wonders with in here before, I don't understand all that nonsense! Thick as sh*t!
The outline is the most rudimentary voronoi noise function, edited afterwards by your Friendly Neighbourhood Shader Nodes.

These are laid over a completely flat ground, no terrain nodes. Cracks are 10m scale:


And laid over a default terrain, POV = 50m Y:


And POV = 100m Y:


Lay them over any terrain to crack it up a bit. There will be different scaled shaders, too. See next post.

*EDIT: Upload folder is full, probably tomorrow then, if PS give us any more bandwidth to waste.

Another tester image of two separate scaled versions in series.

10m cracks overlaid with 1m cracks:


Should I make a 100m scale version, aswell?

Also, these are contained within a single node(per scale set) for ease of use. Just pop them after your terrains but before your colour surface shaders.

This looks very realistic! I've seen plenty of cracked ground like this over the years, nice work! ,  myself, wouldn't mind seeing a 100m versionm It would be interesting to compare the added detail on various scales of size.

I've found a fair bit of an increase in render time by only adding another scale level.

I could make whatever scales really, you probably wouldn't want to go much over three separate scales per scene, though, two is ok.
Two scale levels are taking me about a quarter to a third extra render time over a one scale set render(a guesstimate, I'll test and report proper times tomorrow).

I like this a lot. Could be good for a sun baked lake bed desert scape or a broken up thermal erosion terrain.

Nicely done

Very nice, I was just looking at some pics the other day online of Devils Tower and if you inverse this you may have something to make post piles.

nice cracks !

[old_blaggard]

Nice job. The cracks themselves aren't that new, but I really like the way you're blending them with the rest of the terrain.

[EoinArmstrong]

They look fantastic

[inkydigit]

mighty fine crackage!

[Viktim]

This is very good!

Very nice.

Sweet!
