Hey all,

I probably won’t finish this…but either way I’m sure I’ll learn something and have fun anyways hehe :slight_smile:

So…here’s a test I did using 3dsmax 7.

All of the deformations and physics are done using reactor (specifically, rigid body and cloth dynamics)…no special scripts…just outright setups and calculations.

Obviously it’s NOTHING special yet…I was just playing around to see if I could achieve that instant deform–>freeze that is a property of metal when something hits it. In other words, at high speeds metal deforms like a stiff cloth…yet after it bends and breaks (and the impact is over) it retains its new shape (whereas cloth and soft bodies either fully collapse, or try to maintain their original shapes). Makes sense?

Anywho…here’s the test:

Crash Test 1 (520k, Quicktime)

I chocked it up with some sound too, for those of you with speakers :wink:

Expect some more updates soon…but like I said…I probably won’t get a chance to actually finish an entry for this challenge.

#2

how can i make that ? please.

#3

Everything will be revealed after the challenge :wink: hehe

#4

You got the touch man …ahahaha …this is good … I will pay more atention to the weels and try to fix it to the car body and dont let it deatach to the car … of ccourse ( if I can do that :wink: ) for now my crash looks like nothing hahaha, I have nice deformation bad fisics responces … :frowning: …

well good luck

#5

heehee can i open the secrets?

#6

well as u r courious about how is is done.here is the file that shows u.how it is done.
well it seems very easy on low poly model.but if u r gonna use high poly model like car.than it is very hard to simulate car as a cloth.:twisted: i suggest that donot try cloth or any softbody simulator to simulate car crash.it will take hours of time to simulate the animation.well i found that using reactor cloth modifier and cloth collection in max, u can achive car crash animation.
but with cost of times.than i don’t think my computer can do.

well so what i find is using reactor u can’t deform car.deformation works good on low poly model.but when it comes to high poly models like car than it will take time to simulate deformation.

anyway good luck.

Great job the_jigu. The impact looks amazing. The only thing I don´t like very much is the Tires. Anyway great job. Thanks you for the file too :slight_smile:

#8

hi the_jigu ill test a litle and try to configure rigid body to do that … TX

Hey the_jigu…thanks for hijacking my thread! :smiley:

Here’s my latest test that I made today. NOTE: this is just a test, and doesn’t represent what will actually be happening in my final fx animation (I’m planning on doing a live action mix for that).

Basically, I made this to see what the simulations would be like on a real car model (the model is not mine, btw). Overall…simulation time is very short still…maybe 30 seconds to a minute in total.

Also…for all of those wondering how I’ve done the soft deformations and rigid body combo…well…the method has been guessed correctly in several other people’s threads :). Basically, 1 pass for the cloth sim, then 1 pass for the rigid body sim. When combined, they create a seamless “crunch” animation :smiley:

Anyways…post your comments!

Woo … nice motion, nice crash you got the touch!!!

mmmm I can see for your word that may be Im in the rigth way

Well tonight I will drive my car at 60 m/h and look for a nice tree and watch waht happend…this can be paintfuly but is for a good reson…

#11

hey thanks all u guys!! heheh!!

hey ivanisevich i saw ur second test!! i love it man!! very effective!!
but i think it is still low poly car.as i said it is very hard simluate high poly model using reactor.it will take time to play in reactor.anyway now i must u have some secrets.well after this challange open ur secret!!

if possible this spy(jigu)(i mean me) will open ur secret!!
i m spying ur computer man!! hehe!!:twisted:

#12

hi ivanesavich!!

after hacking ur computer(hahah):twisted: i got ur secret files man!!(u know i m working in FBI)
i got it how u use rigid body and cloth pass to simulate this animation!!
first u have created animation for rigidbody (“car” as a rigid body object) than u have used cloth reactor to simulate cruches!!
anyway i got it to working on my lowpoly model!! but when it comes to high poly model!!
my max get hangs out!!

here is sample divx avi that shows animation i have done!!
animation looks bit strange becoz i didn’t follow meshflow in my model!! modeing low poly with right flow is also important in simulation!!
sorry for hijacking ur thread!!:deal:

Hi the_jigu,

Well…the model’s at 98,000 polys right now…so I’m not too sure what your definition of “low” poly is. I’ll also be modelling some of the interior once I’m ready to do the final comp. But overall…as I mentioned, the cloth simulation on it takes only about 30 seconds. Combined with the different rigid body simulations in the scene, total dynamics computation time is only around 1 minute.

As for hacking my computer…the one I made that on does not have an internet connection installed in it…so have fun! :smiley:

Anyways…your model is still flopping around in your test there…and it’s obvious that you’ve just thrown a soft body controller on it. Also…there’s no “crunch” on impact. The back end flops forward when it hits, intead of the front end collapsing in on itself. If you’ve ever seen a crash test dummy vid…you’ll notice that often the back end of the car remains intact while the front end is totalled (after hitting the test wall).

Anyways…I’ve been thinking about what I’m going to do for my final movie…for a while I was thinking a live action comp…but now I think I’m going to do it totally cg. Ah well…we’ll see…I’ve still got a month to go :wink:

#14

anyway ivanesavich u r doing simulations to high poly models!!
so ur secrets r secrets!! but i hope u opened after this challange!!
man u r doing awsome!! i can’t wait for ur final movie!!
but i think my guessing is right about reactor simulations u have done!!

#15

holy ****ing shit
i want to know how you did that and I want to know NOW!
damn seriously you have the most potentitial I say in this contest
all you gotta work on is not to make it stop so suddenly after impact
maybe you will add fire or some debri in the wind or something but its tooo dead after the impact

please tell me how you did this
i will help you with lighting and compositing if you want

#16

oops!!:rolleyes: anyway well u said about my model!! well that’s the testing model which is not modeled correctly!!
i saw ur crash!! it;s amazing but my though about ur crash is right!!
u have did first rigid body animation and than u have done cloth or softbody simulation!!

anyway tell me ur pc configeration!!

i have AMD 64 bit athlone 3000+ on asus a8n sli deluxe mother board.
512mb ram and geforce 6600 gt pci-express graphics card. system is running on 2.2 GHz.

now let me know ur configeration!!:slight_smile:

#17

My setup is nothing special…

P4 2.8
1 Gig Ram
Ati 9700Pro

#18

your gonna ignore me?
lollll
ok ok i get it
no seriously can you just direct me to a simple tutorial on getting the deformation right?

#19

I’m not ignoring you man :wink:

But I said above that I won’t let on to any “special” techniques until after the challenge. Wouldn’t be much of a challenge if everyone knew how everyone else was doing their stuff :wink:

I don’t know of any tutorials covering the subject. I got my results from playing around.

The crash is amazin ivanisavich. Looks so real… The camera, the model, the speed… Congrats man!
