Maya 2016 tutorial : The basics of Bullet physics explained

[@seanayres5]

Thanks man, was trying to figure out how to do this for ages and somehow got the idea it was related to nCloths. Gonna run up some cool simulations now!

[@MHTutorials3D]

Have fun !

[@VinzswellSimon]

At school, we're using Maya 2013 so I didn't know how to set collision on objects here on 2017. So thanks for the tip bby

[@OstrovTv]

Thanks! really helpful! Especially how to find "Bullet" menu! ))

[@TakuyaUMEDACHI]

Thank you so much for this informative video! This is just what I want to know!

[@ashleymitchell9155]

How can I move the effect to later in the timeline? I don't want it to start at the beginning, but maybe 30 seconds later. Is it possible to delay the effect in the timeline?

[@gillianchan6637]

Hi,can I ask a question? When I select all these cubes and click "Active Rigid Body",after that when I select the bulletSolver in the outliner,all these cubes are surround by white lines as if they are selected(but these cubes are not selected in outliner),when no object in the outliner is selected it is still the same,how do I solve this? I would appreciate if you can answer,thank you.

[@MegaKosan]

YES. I'll watch it later ^^ Didn't expect you to deliver the video in such a "near future".

[@MHTutorials3D]

+MegaKosan :-) Hope you like it !

[@MegaKosan]

+Mike Hermes Hey Mike, I have a question: I shattered a cube using the shatter tool you made a video about. How can I get that to work with bullet physics. I tried it with and without jagged edges. Is it even possible? Everytime I try, everything just explodes. Thanks in advance, you are a great source for learning Maya. -Kosan

[@vforvisuals1151]

Nice Mike 👍 Thanks

[@joshgilbert9571]

This bullet thing just does not work for me. First they was just clumping and overlapping at the to the centre of the grid after pressing play. Then i did the whole scene again and it didn't clump but now they don't even collide with each other???? what is going on???

[@indigojarl8913]

@Mike Hermes How can you control a passive/active rigid body in maya's bullet system without using inital velocity or dynamic properties? I tried grouping the passive/active collider inside itself to move it around and keyframe, but that doesn't change it's collision corridinates.

[@pratapmistry7659]

you did not mentioned in which unit and which frame playback speed we should work...//?????

[@stever73]

Great stuff as usual, Mike. I had a question. I'm experimenting and creating something similar to your demonstration, however I want the ball to be "rolling" through the stack as it's falling. I tried the ball as a passive rigid body and it didn't move so I turned it into an active rigid body. I needed to reanimate the movement to the ball but the cubes don't collide with it, it just passes right through. Suggestions?

[@MHTutorials3D]

Have the ball fall straight down and then tilt the camera so it looks like the ball is going from right to left

[@stever73]

Turning the camera won't create collision, though, right? I'm looking for the blocks to collide with a moving object. I have the ball moving but it "phases" through rather than actively showing a collision.

[@jarrett408]

Hello, Mike first I'd like to say I'm a big fan of your tutorials and all of them are super easy to follow along. I know it's super late and you probably won't be able to get back to me in time which is perfectly fine, I was wondering if there is a way to do not just reverse gravity but have the repo mash start from the collider object/floor and go back to its original state?

[@zirytowanaplaszczka2318]

hi, I have problem. When I use Bullet and active active rigid body, maya says "// Error: Failed to create evaluator for "drawdb/geometry/bulletRigidBodyShape" classification because the current drawing API isn't supported.". I have maya 2017. Could you help me? :(

[@bramvandriel4592]

Have you been able to fix it got the same problem...

[@GareGix]

hi Mike, when I use the bullet in my scene, the object disappears and I have on the translate attributes "Infinity". It isn't in the center of the world, it is the reason, because when I did it on a new scene, it's working. If the matter subsists, how can i export the animation of a falling object from a clean scene to the other scene? Thx

[@donatesmile202]

Very Interesting, Informative,Helpful Video......Thank You Very Much Mike Sir.

[@MHTutorials3D]

You are every welcome

[@shravanthian8466]

sir in my computer the mesh was not rotating in x y z angle and object also not view in 3d what I have to do please guide me sir

[@P_chanG]

It doesn't work for me.. i don't know why. I put "active rigid body", play, and nothing happens :(

[@ByDany495]

im trying to do some ice cubes falling into a cup (nothing fancy), but when i apply the passive to the cup, the shape of the cup in the collission view is not in the same position as my cup model, and i cannot figure out why

[@raularosemena]

the thing with collision in bullet, the collision object has to be in the center of the grid, there you create the collision object, and then you can move in to where you need it to be

[@yungamogus5767]

Hi Mike, am trying to follow this tutorial but the "ground plane" option is not in my bulletsolvershape1, solver properties. Any way I can bring it back up or relocate it? I am using Maya 2014 just for your information.

[@MHTutorials3D]

To be honest I don't have 2014 so I can't check. Maybe some other viewers can help ?

[@yungamogus5767]

It's alright. I found another way to do it by creating a plane polygon on the grid and making it a passive rigid object so the cubes can interact with it. Thanks for the fast reply and love your tutorials!

[@66yahoo6]

Hy! it seems I have a problem whem rendering with mental ray, I have a floor as a pasive object, and a shattered cube as an active, in the software everithing seems fine but in the render the cube passes throu the floor

[@VideoJamesNZ]

This is SO COOL! Thanks Mike! 😊

[@MHTutorials3D]

Very welcome

[@tlc4056]

Mine are not falling from above, rather moving in a horizontal directions instead of dropping vertically, any ideas why please?

[@MHTutorials3D]

Check the direction of your gravity in the attribute editor

[@r2g0]

Thank u so much!!! I love it!!

[@christopher8116]

Mike are you knowledgeable with Kinematics and Bullet ? I have a question to which I've asked around and around and around and no one can answer ?

[@MHTutorials3D]

Christopher, Join my Facebook Hangout group. I am sure someone can help ( well over 200 people now ) facebook.com/groups/294359217578724/?fref=nf

[@christopher8116]

I'm not on facebook.

[@christopher8116]

I'd like to test How much Mike Hermes knows about Bullet. Here is an example, how do you constraint a dynamics object to a particular axis but also keep the dynamics object in a particular spot in world space ?

[@ishansur1465]

Hey Mike, if the cubes are stay at the grid and the sphere are coming to the cubes then what should i do...? please reply

[@MHTutorials3D]

You have applied the field to the sphere instead of the cubes

[@graphicbender7755]

Hey Mike !! Can we do the opposite??? I mean the sphere should hit the bricks. Let me know

[@MHTutorials3D]

Sure, remove gravity from the bricks and add negative gravity to the sphere

[@graphicbender7755]

thanks Mike !! But can you first tell me what is Ground plane about in the Outliner? what it does? & what are active and passive bodies?

[@MHTutorials3D]

It makes sure the pieces don't just keep on falling

[@aakanshamisra7863]

I don't have bullet option in my maya 2016 version. please help.

[@claytonmeininger4282]

Hey Mike big fan! I'm pretty new to maya and I was wondering if you could do a tutorial on how to model a clone commando. Mainly how to model the armor. If you can't do the whole thing just the helmet would be nice. Thanks again for all the help!

[@MHTutorials3D]

+Clayton Meininger I will see what I can do Clayton :-)

[@claytonmeininger4282]

+Mike Hermes Fantastic! Thanks so much!

[@ethanw611]

PLEASE HELP!! I turned on bullet, but no longer need it anymore. Whenever i scrub through my timeline, some objects get positioned oddly and whenever i re position them, they just go back to the same spot whenever i scrub again. How do i 'disable' bullet?

[@ethanw611]

+ethanw611 I have also clicked 'delete bullet from entire system' but that does not work either!!

[@MHTutorials3D]

+ethanw611 Have you deleted the history ? Also go to Windows - Outliner and delete the Bullet there too

[@ethanw611]

+Mike Hermes That seemed to solve the problem. Much appreciated!! :)

[@MHTutorials3D]

Cool

[@shikamaru5608]

Cool tutorial! Do you know how I can bake this simulation into an animation and export it to a game engine like Unreal 4?

[@PivotStryker]

I know I'm 2 years late but you can probably do it by keying the translation and rotation of the objects at frame 1 and whatever your last frame is

[@quantum_psi]

Hi Mike. I'm trying to apply a passive rigid body to a tube that i made for a ball to go through, problem is that it's literally going straight through it like it's air. I used ep curve tool and a cylinder that i extruded. Does it have anything to do with it? I also checked collider type to mesh, and still same result. (Same result for all collider types)

[@MHTutorials3D]

Is the cylinder a polygon mesh or a nurbs surface ?

[@quantum_psi]

Nurbs surface

[@MHTutorials3D]

That's the problem. Convert it to a polygon mesh

[@quantum_psi]

Thanks a lot!

[@quantum_psi]

Seems like that didn't work either. ERROR: No valid items selected Don't understand this, i've asked so many people and they're clueless to it as well.

[@cdmar33]

I also see abcbullet in the plugin list. Do I load that too?

[@MHTutorials3D]

+cdmar33 Only if you are going to use it

[@zombie_slayer3571]

Omg!! Is there a way to do this on Maya 2011? can I install the Bullet plugin manually for maya 2011? please yes.. I really can't use a higher version than 2011 in maya, because I can't Export it to the game engine then...

[@MHTutorials3D]

+Zombie_Slayer I am no sure but you can do similar things with Dynamics / nDynamics

[@zombie_slayer3571]

Mike Hermes Exact same? Like Having some blocks above falling down and colliding some things? I'd like to add a cool scene to my mod

[@MHTutorials3D]

+Zombie_Slayer This video in 2014 shows the same principles in Maya without Bullet and should work in Maya 2011 kzbin.info/www/bejne/gZPPYn-XbtWeiZY

[@samirmehtiyev32]

Thank You Man. You Are Awesome !!! :)

[@luigirazvan8940]

make a tutorial about animating the cycle walk

[@vazak11]

Cool!

[@adnanekaboun6105]

merci

[@bananatree7781]

man ur a boss

[@masterryu6356]

Master... do you know how to make cool smoke stuff? Like in the video with this name "The OMEn Chronicles - Harry Potter -4K"

[@MHTutorials3D]

+Master Ryu Do you have a link ?

[@masterryu6356]

Mike Hermes Give me a sec.

[@TheRealDevx]

+Master Ryu yeah few toturials on smoke dynamics will be great ;D

[@masterryu6356]

WhoTookMyName100 Make some or lead me to some. Not in the mood to search xD

[@Ibraam.Victor]

system requirements

[@MaleeshDedigama]

Can you export this into nuke?

[@MHTutorials3D]

Not sure, don't have Nuke

[@lingojisameer6977]

please can u send plugin (link)

[@MHTutorials3D]

Bullet is part of Maya

[@lingojisameer6977]

no it's not there in maya I thoroughly checked it

[@GareGix]

it is in, he shows at the beginning of the video how to do to make appears "bullet"

[@shubhambisht183]

my question how to bake this

[@TGFilmstudios]

cache

[@anthonymcgrath]

i've been battling with bullet all day and come to the conclusion it utterly sucks! I have a heap of rock geometry shapes, i set them as a rigid set setting them to hull object (or cube or sphere it literally makes no difference!), i then create a simple poly cube to act as a floor but they just fall straight through it. unique names, no history, transforms frozen - you name it i've been through it - bullet wont play ball - its utterly crap! its cute if i want to make cubes fall onto an invisible ground plane but for anything real its terrible - lost a day of my life to this rubbish! sorry i'm angry and venting lol!

[@T800System]

I've had the same experience. It's extremely buggy - unusable imo.

[@TGFilmstudios]

same in 2017

[@petar932]

to everyone who says they lost time, lol nope they didnt. it is a learning process, and something that feels like its a useless experience will be 100% usefull in future with some other code
