Exploding any polygonal object! Using only the built in c4d tools of 9.5 and Mocca.

Hey all! Was working on my animatic for my short (http://forums.cgsociety.org/showthread.php?t=276040) and I thought of a way to get a fairly nifty way of breaking an object apart with pretty good physics.

Wow, I didn't think it would go over this well :D At work for awhile, but I'll try and bang it out when I get home. I nearly killed my computer when I did the same thing to the Meg model, but it did work. I know there are a buncha neat tricks that can be done with it, I've only just touched the surface with my own tests.

Perhaps you can have some fun with this while you are at work and give us a tease. I need some background multitasking things to think about and this would be perfect! :) I think I have some of it work out, but... Deformers? Cloth (Only)? Dynamics integration? Plugin? There's got to be a nifty little trick right? HELP!!!

Honestly it's nothing overly fancy, depending on what you try and break apart setup is pretty quick. I'm trying to work out a "shatter' type one right now. Speaking of running things in the background. I'm rendering out an animation while working on this o_O More as it happens!

jkirk01
02-17-2006, 06:00 PM
I tried using Explosion FX deformer, but when I enable cloth/collider or setup dynamics with/without cloth, the deformed geometry doesn't seem to want to collide with other objects in the scene. Yes, I played with eps, different collision settings, etc. Not sure what's happening. Perhaps someone can enlighten me? :) Thanks...

This was keeping my mind busy all day long - I couldn't sleep if I hadn't figured out how you did this. :D So I kept experimenting with different cloth setups and I discovered something which works quite well.

So is this your setup too?

- Object you want to explode (lets say it's called "Otto") gets a Cloth tag with extremly high Stiffness value and Use Tear active.
- Clone Otto, rename to "Otto_helper", scale him down a little bit, animate the scale of Otto_helper bigger again (over 2 or 3 frames) so that it pushes the original Otto outwards and over the Tear percentage value. Add a Cloth collision to Otto_helper
- Add everything else like ground and sweeper and add Cloth Collition to those too.
- Don't forget the cloth Nurbs object for correct tearing (and also for the thickness of the particles)

Here's my result:

(My EPS settings are a bit too high so some are passing through geometry)

You know, I was thinking that exact same thing but my tests sucked sofar. Yours seem to be real close! :thumbsup:

Edit: Wow I still cannot succeed in getting the right settings. Something is exploding now better but I don't get it right. The exact combination of settings is crucial to get the wanted effect I guess. Ok, a little more testing and then off to bed... :hmm: Congratulations Creature for succeeding!

Edit2: YES! It's working now way better. Not as clean as the other examples yet but I will succeed. Thanks for sharing the secret Creature. Curious to know if Kico used the same solution... :)

02-19-2006, 01:55 AM
I just ran a few tests also for fun... But with Flex and Rubber at zero and stiffness at max. Then I also expanded the inner model and I cannot get tear to actually tear? Not sure why? The exterior model deforms all over the place, but does not tear. I have tried the lower percentage settings and even higher settings and no luck :(

Guess I will have to keep playing...

Not to far off Creature :) I'm amazed at the interest in this. I think you found a good way to do it if you don't have 9,5. Would be great is one of our oh so awesome plugin guys at cgtalk could probably find a way to do this for real, rather then my elaborate way of faking it.

If anybody has any questions about the tutorial, feel free to post/pm/email me. Makes me happy I finally came up with something people want :D

Great tutorial! Thanks so much for posting this :thumbsup:

The thing I'm having the most trouble with is getting the object to be broken but not look broken.

A trick you should try is that it doesn't have to be perfect, but you take the copied (Unexploded) version and have it stand in for the Exploded one. Record the Visablility for both, then the frame before it blows up, you switch the non-exploded and the exploded and record their new visablity. A stunt double you might say. This is what you must do if the object is to be moving before it's sad demise :)

Another trick, to stop anything from happing for a few frames.

In the Clothilde tag, under "Tag" uncheck "auto" and change the start to the frame you want the fun to begin.

Hope that helps!

Chris

Very nice! I'm still working on getting a good "glass shatter" effect like you did in the initial post, but I'm getting there. I find it quite entertaining that the effect very much rivals the $1500 Maya blast plugin. I know it's not quite the same in ease of use and all, but I think we could get some very similar end-results -- and that's what matters, right? (that might make for an interesting mini-contest -- to re-create some of the Blast Code (http://www.blastcode.com/) movies)

I don't think anyone's mentioned, though, and it should be noted, that the tutorial (as written) requires 9.5 -- before that, you couldn't apply particle effectors to cloth. But, I'm sure variations will pop up (as they already have)... but hey, one more reason to upgrade :)

Thanks again for the great idea/tutorial.

Interesting to see this is a whole different approach than I expected. I was also looking in the direction of Creatures solution and finally succeeded also in making a lifelike explosion. So what are the advantages of each solution? I think your way gives more control over the different particles that's for sure, but overall the visual effect will be the same I think.
Very cool, thanks again!

Nice pyro Spongebob2!

The bits on the floor are constantly being pushed away because the Attractor is rather large is still touching the pieces. You could either make it a bit smaller, or turn it off after the first few frames as it doesn't really do anything to the object after that. Great job :)

If that's the case send some projects my way! I could definitely use the money! :D

The way I would go about creating that effect depends on the objective of the final output. Some random notes about the one I had.

~plane started out as a "disc" shape, so that it would look like it had cracks running from the center out.
~the particle "gravity" seems to kill off the spinning of the bits, so I have to use the gravity from the clothhilde Tag. But to use the gravity from the Clothilde Tag would make the whole thing fall.
~To counter that, I had the gravity in Clothilde recorded at 0 until the frame that the sphere broke through. Then I recorded it at the default. That's why the whole plane falls after the crash.
~ I'd have to put a bit of thought into how to do it for an plane that wasn't to fall after the crash, but I don't think it would be too hard.

I'll post the scene file in a bit :)

Thanks Kico82, i never would have thought of using the disc instead of the plane. That's genious. Now i see why it shatters like a glass would by using the disc.

Well Maximus... I'm not sure wat going on here. But when you're expecting to see an explosion, that's pretty darn funny :)

I think that you're object is not getting broken apart by the Explosion FX deformer. Try the new setting I posted just a bit above. Also, be sure that you do the "Current State to Object" Otherwise it's still one piece.

Hope that helps!
If not, post a scene file

Hehehe :D it's so weird it's funny, i couldn't agree more as i were expecting a big fat explosion and got a bubbly big spikeball :D

Actually i did a exact replica of your exlosion scene, just used a cube but that shouldn't cause such a weird result, and i even did the Current State to Object as you wrote in the tutorial, ..still it seems my computer is possessed by evil spikey and bubbly forces :D

Anyways, i'll give it another twirl tonight and by god i hope i finally get some kinda explosion, as long as my computer don't blow up... *knock on wood*

Btw, i'm using 9.5.2 so it should work fine :)

Yeah, Im just wondering.

Does the maya plug-in take up so much memory and work- time as Cloth?


Because productability is a factor in here.

Fist off, thanks for a great tut. Way to really use the tools. I tried doing this in r9.1, and pretty much everything seems to be there, expcept the atractor and turbulence don't affect the cloth object at all. I just get a glass ball that falls to the ground and shaters (which looks pretty good in its own own rite). My question is, is particle affectors affecting cloth objects a new feature added to r9.5?

There I was just watching the explosions in awe, when along came this wobbly thing....this is just as much fun as the bangs! It looks nervous to me, maybe it knows its about to explode :)

What were the setting in error, definitely preserve them for when we need "nervous wrecks" etc!!

Yes. One more reason to upgrade!

There's another method on page 2 or 3, I think, that does it differently and doesn't require the particle affectors, though.

Kico, simply brilliant! I call these kind of moments Zen moments. That is when something comes to you way out of the blue and you astound yourself. I'd like to know the story behind this discovery. It took me a minute or two to realize the forces at play in this simulation. I have some additional ideas using this method. Thank you for so much for sharing...

I was rather surprised when I figured it out. I've been working on the animatic for my short (http://forums.cgsociety.org/showthread.php?t=276040) and in one scene a tower blows up. Since it was just the animatic I figured it'd be silly to put a lot of work into it so I just knocked it apart with Explosion FX. The camera didn't look at it long anyway.

Anywho, I was getting to the next section of the animatic, and it was to focus on the rubble of the exploded tower. It was built on uneven ground, and I thought it would look bad if I just scaled the bits down on the Y. I thought about it for a second, then did a "current state to object" on the whole exploded tower, made it one object, dropped a cloth tag on it and a collider on the floor. Pressed play, and all the bits fell right to the ground like I knew they would. La la la... Wait a minute... why not just explode the tower with cloth and a negative attractor?! My first test I tried with my idea is the first video in this thread. I was very happy with the result as you might guess :D

Anyway, when I first watched the video. I was amazed how realistic the explosion was and how it was interacting with the environment. Chris, you're amazing for discovering this. This was much better than my noobie explosion I was doing in class. I was thinking about doing an explosion by using Thinking Particles.

I definitely can't wait to watch this short. I want the high definition version :D.

It was just for fun. I wanted to see how the behavior and dynamics worked in this method. Night before last I added a omni with volmetric light in the center of my furball. That turned out really cool too. I'll get it linked up tonight when I get home if you guys are interested...

Hey, i have a problem here i folowed all your steps on the cloth boomer tutorial (with the platonic object) and for some reason the object does not explode, I put thje turbulance and attractor under cloth tag>Expert>Include and the object still doesnt blow up, even though i made the properties of the turbulance and attractor the same. I dont know what is wrong here.

I really want to make something explode!!

AkaKico
03-30-2006, 03:02 AM
Hmmm yarko, hard to know what went wrong. Is it possible for you to post the scene file of what you tried? As an alternative, open up the example file I provided and see if your setting match what mine are. If I had to guess though, I'd say that the problem probably lies in the FX deformer and giving the Platonic thickness. It's the tricky part :)

yarko
03-30-2006, 05:36 PM
it just falls down and breaks, it does not explode, its as if the particle attractor and turbulance dont work, ill try to post the scene file.

thanks for the reply.

Hi There

Fantastic article - just what I needed BUT!!

I don't seem to be able to animate the cloth object, but you have, at least the plane animation suggests it.

How did you do the plane? Can I animate a cloth object? When I try only the axis animates.

Cheers
James

Just in case - I mean the aeroplane animation.

04-19-2006, 09:25 PM
Oh yeah - there is is...... (knew that would happen....)

Ah so you used 'wind' to move the plane, tricky. At least this seems to support my experiments that you can't animate a 'cloth' object (is that bizarre?)

Sorry everybody - I seem to have made my own personal thread here!!!

James

AkaKico
04-19-2006, 09:43 PM
All good James,

Yeah, once you are using the dynamic from cloth it's pretty much wherever it is. A trick though is to make a second object that is not cloth, animate that, and then the frame where the breakage happens, switch objects! (Hide one, unhide the other)

Chris

jamesinnewcastle
04-19-2006, 10:26 PM
Not being able to move a cloth object just doesn't make sense? Maxon have a ghost on their site which blows around and is a cloth. Any idea how that works?

If you wanted to animate a girl in a dress walking along (say) Would she move off and the dress stay still?

James

AkaKico
04-19-2006, 10:33 PM
the ghost moves because there is a sphere under it, a dress would move because the woman under it would be moving. It's all one mesh atop another mess. But this explosion trick is a mesh that has been broken up into a whole bunch of little pieces, when anything touches it, it breaks apart, a single mesh would stay together. That's the difference.

Hey J3,

The figure smash is pretty straight forward I think. I'd host the file but it's giving me an odd "Incorrect File Structure" message when I try and open it. the figure was broken apart with the same method as the tutorial and given lots of thinkness before being made "current state to object". Then I made sure there was no gravity in the cloth tag and animated the sphere with a collider tag.

Hope that helps!

Chris

Alright man, I have been blowing things up all day, it's just very difficult to get the settings just right so it doesn't look like the object is already shattered! Some objects seem nearly impossible. If you set the blast speed too high then it looks all broken up, and if you set the blast speed too low it never actually gets full broken up.

Thanks again buddy, very good idea :-).

Without this method, well when I get it perfected I will be able to save 1. alot of time and 2. not have to model in nurbs when I blow things up :-).

Here is an optimized version of the Explosion FX Deformer with the settings I found work best.

For those of you like me who don't use FX too often I recommend opening the file and setting it to be default under the attributes menu "edit" "set to default"

Of course you still change the Min/Max Polys to change the cluster size and still change the thickness to suit your needs. Other then that it should be all ready to go.

Hope that helps a bit for all your exploding needs!

s awesome but I can't get it to work, when i make one all that happens is that the sphere turns into almost a piece or rubber and kind of jiggles around without exploding into segments? Also the part where you change the shape of the turbulence to a sphere is a that a feature you only get in R9.5 or can I access it in R9?

Thanks!

AkaKico
10-07-2006, 06:57 PM
I'm not sure why it's not breaking for you, I would guess something wrong happened at the Explosion FX part when you do "current state to object" I suggest starting over and trying the part again. Also, this tutorial was made with 9.5. I don't believe you could even use turbulence or wind or the attractor at all with R9's cloth. But it should still be breaking even without.
