How do you do a explosion in asteroid field?

[Valter]

Hi guys.
I have a animation of a nuclear explosion in an asteroid that located inside a asteroid field.
I'm think how should to do it. Maybe I should to do:

3 points groups to use fxlinker
first group will contain thousands of small asteroids
second group will contain hundreds of medium asteroids
third group will contain many big asteroids.

I don't have any idea how add explosion effect to start colision effect between all asteroids inside groups. Some asteroid will collide and break up.

do you guys could suggest idea to do it?


thanks and excuse my english

Just so I understand:
The shot opens on a cluttered field of asteroids.
There is an explosion in the middle of the field that shoves all of the asteroids out of the way as the shock wave advances.
Is that right?

I think your approach would probably work. If you aren't too close to the field, you might consider hypervoxels for the small asteroids rather than objects. I'd also lean toward multiple groups of particles to get more variety.

An expanding wind field in the middle should give you the results you need.

hi :)

thanks for reply :)

Yes you right !!

well, I don't get success with fxlinker. I did use lw spray points to create particles for replaces with an asteroids object in layout, but fxlinker do not recognize like partigons. I'll looking for a plugin to convert my points for partigons.

I'll need to do a zoom in the asteroid so I'll have a take very close, because I'll show the nuclear bomb planted in the asteroid:)
I'm using HV to make a fourth group of very small asteroids.

My concern is about explosion and fragments of asteroid colliding.
Will FX Collision works very fino to do it?? Should I set fx collision to all asteroids near of explosion field???

Thanks again for reply and excuse my english

try to morph ur asteroîds fragments and a some different size of particles in his propertie then ad your wind effect and after maybe a displacement map for the "shockwave" effect

Oh Christ!! Do you kill me??:eek:

I have almost 70 asteroid in region of explosion and I need explode 1 asteroid and others 69 will be fragmented.
Then I will begin to be a madman before finish this job:D

but morph is good way to make explosion in somethings, but I think not in this case.

anyway thanks for reply.


c'mon guys make a sugestion please. help a brazilian guy.
