Cracks in the ground

[mouj]

Well i was about to point you to a tutorial that shows exactly that using an animated extruded spline with boolean... :p
but it does the trick if you do it well, add some debris flying around the crack using particles systems, some movement on the "seperated" parts, a nice camera motion and so on..

Else i don't know, you'll have to think it over and come up with a new solution : )

OK, here is a tutorial on creating cracks. Just in case you want an example.

mouj, I'd like to see it anyway, may be it's better than I thought, point to it please.
Tom Lunzer, didn't you forget the link? :)

Few days ago I tried to create a similar animation, veins growing out of the ground, pushing it, and cracking is open... I screwd up the whole cene, so I dumped the idea, but still, it maybe can add some ideas...

I've used the following method:

First, I've created the ground from a plane, deformed it, and added some resolution to the grid. I think it was a 5*5 gridded plane...

Than in editablepoly mode I created the basic shape of the starting cracks (only lines, not the final crack shape), in really low poly. counts.

When I had all the crack shapes, I adjusted the plane grid to the shapes, to eliminate too small polygons.

I've chamferd the crack shapes (edges) with a chamfer distance of 0, to leave the newly created edges in the same place.

After this, I've animated every vertex of each carck (abou 30) by hand to create the shape of the final carck.

I've deleted the faces inside the cracks, and exruded the sides of the cracks downwards.

Finally, I've added some adittional detail to the cracks by adding some extra edges, and deformations.

After the meshsmoot was added and the vertex weights were adjusted so the cracks remained sharp, I've added an extra "vertex weld" modifier on top of the stack to hide the smoothing lack around the crack edges in tle early stage of the animation...

(I've also added some reactor calculated debris to fall inside the cracks)

IMO this is still only good to give some ideas to biuld upon.

Good luck!

Hey Aldaryn, now that's an original way of doing it! I'll try this as well, thanks :beer:
But nevertheless may be someone could point that spline-extrude-boolean tutorial?

Hey guys, not sure if you guys are looking for anything like this, but I made a video tutorial a while back which explains how to animate the ground cracking apart into a big crater, it might be applicable to what you're trying to make.

It's procedural modeling #1 (I didn't make up the titles).

Let me know if it's any help,

cheers

hithere,

Just and idea... you could use CookieCutter (Shape merge)...
and olso there wouldn be much trouble animating it if U kept the merged spline as an instance...

cheers
