Hi, i'd like to know if there's any technique to create a glass shatter effect with a good reflection and a proper shatter pieces.

Here's the example.







Thank you any help would be awesome.

I have a glass shatter at the end of me reel.
https://vimeo.com/38574977

I used either Xplode or xbreaker (http://nitro4d.com/blog/freebie/thrausi/) for the shatter piece.

Then I used a simple shader with very high transparency, 1.4 refraction and adjusted the absorption length to fit my scene.

Reflection is almost always a sky object with a studio HDRI on it (just load it into the luminence channel of a material. (then use a compositing tag to hide the sky object by disabling seen by camera.

Add your dynamics tags to what they need to be on (most likely a fracture object) an let it go.

That's an awesome reel, but i'd want a Glass break more or less like the one in the example with the slow motion effect (wich probably is jutst done with keyframes or post production) (?) what i mainly want it's the positioning of the Pieces of glass and how to properly break them i used a regular explode effect and this is as close as i got.

As you can see i neither know how to get it to reflect a stock footage.. like in the example wich reflects slightly a city stock.

If someone could take a look into it. And try to fix the motion to look the same as the one in the example or explain it would be awesome !!!

Sorry for double posting. this is what it should be looking like after the rendering from cinema 4D u can see the reflection and the slowmo.

I don't really have time to play around with this but since you are not actually destroying an object you could use a simple emitter with really slow settings and random geometry chunks.... however the next option is Mograph random effector set to turbulance.

Here is a quick set up that should give you a few ideas... I am not sure if its what you what since your files seemed incomplete...

Thats the SKy material.... try a few different HDR images and watch the difference.
I just used your image but your that artist had a building and stuff so just find the image you wan to reflect and put it in.

You may want to add models to the scene maybe some bounce boards.
Slight motion blur will really help sell it too. (Very little since everything is so slow)
Depth of Field is also a nice touch in the youtube clip.
