Fractured object

[Steve Bentley]

If you have the Thrausi plug in that should be easy. Just fracture the plane (or cube) and then push a sphere up through it. The plane and the sphere will need a dynamics tag (or better tell Thrausi to put one on each by telling it that the sphere is static and the plane is dynamic.
For more random cracking put a random effector on the pusher sphere and tell it to shift the points randomly so you get a spikey sphere.

We’re working one right now (see pic) and it was done with one of the Nitro plug ins (you can do everything they can do in cinema without nitro4D products, we just like how quick we can crack stuff with them)
This was done with a capsule underneath that had a random effector on it set to points.
its not as angley as yours but our outer facets are not dynamic (but could be)

Hey!! a big thanx for responding Steve!!!

I tried that solution before but I had a problem with the gravity. The plane was always falling. Even if i was adjusting the gravity in the project setting/ dynamic parameter, i didn’t have the results i wanted.

Since i want to control the cracking with an effector, a bit like the exemple shown in the video I posted before, I used a target effector with a sphere as target object. Its not exactly the effect desired but it works not bad.

N.B.: I hope you understand well since english is not my first language.

Ah ok (i didn’t get an email with your response so sorry if I’m late to the party).
Under the main cracked plane we put another plane with a static dynamic tag on it, so the sphere pushes up but the static plane underneath keeps everything from falling (or you could just turn off gravity in the Project settings)
