Hi guys,
here's a little useful preset I would like to share. What it does is that the network gives you cracks and tiles, like you see them on dried out surfaces.
Usually the voronoi based noise function generate structures like that, but troubles it that the crack lines are usually way to thick to be used in any sort of realistic render.
This preset as well uses the voronoi, but does two things differently:
1 - Tile profile
You can give the tiles a profile, by incrasing the displacement parameter in the node called "tile profile"
2 - Narrow cracks
narrow, more natural looking cracks, that are warped and disorted downwards are managed through the node called "make cracks"
Hope you find that useful.
Cheers,
Frank
PS: the below is a "no frills" demo render
Thanks very much. Looks interesting.
Thanks Frank. Now I wonder where I saw these before... :)
Thanks Man!
Ooooh. Cool. Thanks Frank.
Sweet! Thanks a bunch for sharing Frank.
thanks a million Frank!...I will look forward to experimenting with this
Hmm, looking pretty good http://www.ski-epic.com/burningman2005/p76b_playa_surface.jpg
I wonder, can this easily be applied to, say, rocks? Off to play...

should be easy. To make it look realisitic like in your photo, you need to stack multiple of those with different sizes and different displacement depths. Just adding one more level should pretty much do the job. Of course you need to switch off the tile profile shader, or reverse its displacement ever so slightly - the tiles on your photo are flat or if my eyes don't cheat me, they are slightly dented.
Here is an exmaple of what i meant with stacking two of the networks.
tgd attached. The "secret" is in the internal network of the sphere, of course.
Cheers,
Frank
Phwoar. Get some glowing lava in those cracks and you've got yourself a fantastic cracked moon.
Dang! That's nice ;D

you mean like this? good old terragen glow effect, now in TG2...
Yup.
You'll be just about the right guy to add a couple of special effects to this rather rudimentary render, Jim. Maybe animate the growing cracks along with a collapsing continents and a collapsing atmosphere and to compose some particles flying away from the surface. That would be really cool ;D
Probably a bit too much work to do just for fun....
Cheers,
Frank

Like in the latest Star Trek :)
Only just seen this but I have to lower the tone:
Frank's Advanced Cracks Oh ah misses, say no more.
Visions of Frankie Howard, Kenneth Williams or more likely Sid James in some smutty 60s/70s Carry On come to mind.
Have you got a tgd of Barbra Windsor flashing her tits? ;D
Seriously though nice work. :-[

What the heck are you talking about?
He is referring to the possible lewd interpretation of "cracks", by mentioning a number of British comedians famed for their rather broad humour. Barbara Windsor featured in a number of the "Carry On" films, which specialised in this mildly smutty form.
uh, ok, in this case the joke unfortunately was completely wasted on me ;D
I don't know most british comedians by their name.
Thanks for the clarification anyway ;)
Frank
Don't worry Mr Lamppost, I got it ;D
"FrankB's Advanced Cracks..... Ohhh Matron, Take them away" (in a Kenneth Williams voice) was the first thing that sprang into my rather sad brain when I read the topic title. Probably says a lot about the way my head works.... shame :(
Anyway FrankB, many thanks for this, most excellent. ;D
Miles
HAHAHAHAHAHAHAHAHAAHAHA. ha.
This has been a good way to start the morning.
Doh, why didn't you post that a week earlier when I was making "Dreadnought" and "To The Wind" :D
I wouldn't have to blur the ugly foreground ;-)
No, honestly - that's a really fine surface! Thanks :)
I had no idea this was here. Lucky me that Cyphyr just pointed someone here recently. COOL work, Frank and Thank You.
I've also added this function to the NWDA CS store, for a tiny fee. So if you feel like wanting to donate something for it, you can do it there: http://store.nwdanet.com
