Ray Fire, Momentum, Implosia

[Emilio Hernandez]

How far is Implosia with Momentum to achieve something like this?

http://www.youtube.com/watch?feature=player_embedded&v=mn3ifA1gcD8#!

I need to break a wall earthquake style with ceiling coming down, small fragments, etc., and wondering if I can beat this Ray Fire stuff with Implosia and Momentum.  Need to win this gig.

Thx.

From my experience of working with Momentum/Implosia on a few jobs and watching some of the videos by MirVadim I would say, that RayFire is better and a lot more intuitive for complex shattering.

The actual simulation speed and directability of the shattered pieces however is many times better in Momentum.

For actual production I would be a lot more confident to make a simulation look the way it is supposed to with Momentum.

Shattering, dynamic UVs and mainly caching are all still a bite iffy with exocortex's solution, but the directability is unbeaten.

There seems to be a new version coming:

Hey Rob,

thanks for the heads up. The change list includes lots of issues I reported some months ago,
I'm glad to see version 4 is taking shape since 3 did have some unnecessary limitations
and oddities which are being addressed now as it seems. It's such a cool piece of software
with so much potential....

One thing I found is that I shattered a cube with Implosia and then applied a Momentum DRB.  When I start simulating it kind of explodes instead of just coming down.  If I shatter the same cube with the ICE shatter compound and then I apply the MOM DRB it behaves different and it comes down as it should.  This is odd...

I think also that new tutorials with voice over will be very welcome!

I suspect the pieces from the shattered object are either interpenetrating right from start or have a collision offset greater than zero. Or you have found a bug.

Hi Emilio,
What kind of fracturing and collision shapes you did use in both cases ?  By default, MOM RBD has a convex shape applied to each chunk, it works well with the voronoi fracturing style, and does the explosion on any other since shapes is not convex.

[Emilio Hernandez]

Mmm.  That is a good point.  I will give the knife some thickness to shatter the object to avoid the interpenetration if there is some.

Hi Oleg.  I am using the Iterative mode.

[Emilio Hernandez]

Yup I think it was interpenetration.  I added a thickness of 0.001 to the knife and it is working ok now!  Now the wall falls down instead of exploding.

Thanks a lot guys!

[Oleg Bliznuk]

Yep, by default the updated Iterative\Voronoi uses true zero thickness to avoid any seams on render ( Continuous still has a minimal inset due to some restrictions of our boolean engine ).

[Emilio Hernandez]

Thanks for your support Oleg.  Moving forward with the Gig!

I am having some problems with Voronoi.  I have the following error:  IFXACCESSOR:Point position data is absent or has been corrupted.

I started with a fresh mesh, transformed it and freeze the modeling stack and transformations before applying the IFX Voronoi Fracture.

Can you send me a repro scene ?
And if you have further any questions, please join https://groups.google.com/group/implosiafx_users :-)

[Emilio Hernandez]

Thank you Oleg.  I joined the group.  Anyway here is the scene. The thin wall is the one with the corrupted data message when I apply the Voronoi.

[Oleg Bliznuk]

Hi Emilio,
Your setup looks very strange, did you have any older ImplosiaFX version ? I see the deprecated compound on your ICEtree, and in addition it has a name which usually was after calling one of fracture scripts in this older IFX package. Try to remove all related stuff from the addons folder and install the newest vesrion. After that you should get top-level menu like on the attached pic, then select your input geometry, press "Create Base Setup" and build something like on the second pic.
Hope this helps,
regards,
Oleg

[Emilio Hernandez]

That looks nice!   I will download then the latest version.  Thanks a lot Oleg!

The latest one ( beta ) is here: https://groups.google.com/group/momentum-beta
Just send a request

Cool thx Oleg

What version of Implosia is available today ?
On Exocortex site it's 1.6, but there is a 2.0 demonstration video
posted on Vimeo 5month ago.

[Sebastian Kowalski]

v4.0 is in beta, and its great!

[Leonard Koch]

Sebastian is such a tease :p

[olivier jeannel]

Thats Momentum 4 right ?
Implosia is no more a standalone ?

Le 19/04/2013 18:45, Sebastian Kowalski a �crit :

[Leonard Koch]

Yeah, as far as I understand they are one plugin now.

Ok,
I gave 1.6 a go today, to help some friend. I had very nice results with voronoi and "bomb" compound, some convincing fractures I mean.
But it crashed so many times, maybe 60 times... I'm completly stressed right now :)
Going for the week end now, haha...

[Oleg Bliznuk]

Implosia is now shipping with Momentum in one .zip package but actually its a standalone plugin ( in terms of installation ). The 4.0 is just a more convenient numbering due to Momentum versioning, and it is 2.5 in terms of improvements I think. Its has been rewrited almost completely, so again - almost no crashes and significally stable behavior on some complex cases. You can try it out via the momentum beta group: http://groups.google.com/group/momentum-beta
