Blender 2.7 Tutorial #68: Shattering Objects with Cell Fracture #b3d

Thanks for watching! Please don't forget to subscribe to this channel for more Blender & technology tutorials like this one! :)

In this Blender 2.7 Tutorial #68 I cover:

- Enabling the Cell fracture add-on
- Using the cell fracture add-on
- how to prevent errors and bad 'shards' and what makes a good mesh
- using the remesh modifier on meshes with bad topology (like converted 3D text)
- Physics simulation
- How to switch between the falling 'whole' object and the shattered object on impact
- Converting physics simulation to keyframe animation
- Using and animating 'excluded' layers from render
- Adding motion blur to renders
-Animating render noise for animations
- Copying a material from one mesh to many other meshes at the same time.

9:54 Thank you so much for that bit of info with the CTRL + J thing. I never quite understood why that kept happening in some of the models I've tried to make...

[mace]

couple of things to add. If you're using a texture you have to UV unwrap and create before fracturing and you didn't cover the interior/internal material setting which is really handy.

[DougieBoy]

Just wanted to let you know that your tutorial videos are amazing and very easy to follow. Keep up the good work bro.

[ajal]

This is the best tutorial for cell fracture and falling thanks a lot.

[alibenali]

im algerian and i dont speak goodly english but i understand all your vidéos :D Thnks <3

[haroldw]

wow as easy as that.
great tutorial, nice and clear

Thanks mate

I have uploaded videos showing the cell fracture and rigid body collision working perfectly in a scene which contains nothing but the object to be destroyed, the plane, and the object which destroys the first object. However, even having successfully done that, when I have returned to my full cabin scene in which I wanted to use the destruction of a door, it doesn't work. The shards just collapse at the start of the animation for no apparent reason despite the settings being the same as in those simple scenes in which it works correctly, the only difference being that the door object is in the center of the scene in the latter.

Tip: If you remove the doubles before you remesh, you get a cleaner topology

[dennisfassbaender]

it would be so much easier for you to use the fracture modifier build from us. you could change every thing on the fly, shards, smaller shards, constraints, debris, everything is changeable with a few clicks out of one ui for all. you would finish this project in seconds! and it's free ;)

i dont think you needed to redo the render layers key frames as you had them selected and moved them over with the rest of the frames

Hey CG, thank you for this tutorial. There was a lot more information here that I found really useful to add to my own knowledge of the system.

But one question I do have is about the animation. YOu used the exclude layers to hide certain objects. Is it also alright to use the eye icon in the layout?

[mohammadehsan]

how to find appropriate sound for it breaking?

[ScheveninGaming]

Is there a way I can choose when the cell fracture begins?

I am trying to animate something breaking something else, but I don't want the cell fracture part of the animation to start right away... any help? Thank you so much in advance.

[yihao]

why my "G" is exploded right away in the air not explode when hit on the ground?

[jackgilltaylor]

How would i have something smashing through an object

[gusi]

And how do i watch the whole animation fullscreen? great tutorial btw

[denislavrudev]

Can I make a sphere into cubes with cell fracture? BTW Great tutorial!

[matthewde]

I did it exactly like you did it, but the word just exploded before hitting the ground.

[ravencroftgraphicsd]

ok, i have an odd Q. what if you want to 'reverse' physics. i.e. you have an animated object you want to shatter, rain, etc UPWARDs? can you do a quick explanation on how to do that please?

[ccme]

Can cell fracture be used to create a jigsaw puzzle?
