During the Red Stick Animation Festival in Baton Rouge Pete Draper and me met to do what we do best:

I had a great time hanging with the guys teaching at the festival drinking by the pool. Pete actually went in the pool fully clothed :smiley:

Wooooooooow dude! That’s da sh*t! On all fronts!


#4977

Jez…thats very nice. Me wants to play too :cry:


#4978

Thanks Galagast
Your script save me a sh@t load of time!
:slight_smile:

Smoking - that rocks. Good for metals and plastics denting, breaking, etc.
Nice example :cool: Would be cool to see this on a tank, car crash or military hardware.

Hi all,

I know to say its been asked a few times in here would be an understatement but it was spoke about recently this year that box 2 would be available end of march but then got delayed again. Any news on how its all going? All the tests are looking like its going to be a huge addition to PF and an essential purchase but a development time of 4-5 years between being announced and still not being released must be a bit of a record ?


#4981

What’s your quesion again? :slight_smile:


#4982

You are perfectly right, Orbaz is late. HOWEVER we all have to keep in mind that orbaz is not a 30 employee company rather then Sir Oleg and a hand full. Further more we all agreed that we prefer a stable and cooked out release over an early one. The implementation of the PhysX solvers was more complicated then intentionally estimated.

patience pays off when it comes to proper implementation of 3rd party software i guess. Its not that we aren´t waiting too :slight_smile:

kind regards,
Anselm

Hey Anselm, thanks for sharing some infos with us, hope we could also shared some beer… :smiley:

I was wondering about the multithread support, it was mentioned to come with box #2 but I have seen nothing on orbaz site about it… should we still expect it? :wink:


#4984

hey guys!
I just wander if there is a script solution to animate particle scale along the time, I m sure there is. Animate the Scale operator by keyframe is not very handy from my point of view.

Any scripter down here? :wink:


#4985

What do you mean its not very handy? what are you trying to get it to do?


#4986

Oh yeah, new stuff! (sorry about the shameless plugging ><)

Finally finished my latest personnal project I’ve vbeen working on for the past few months.

Pflow was used for the floating chunks, the falling debris, the splash sprites, snow, and splashes in conjunction with fume and what not!

theres a breakdown afterwards, and can watch the shot on:

Thanks and enjoy!

Dude check out the scale op, there is a the ‘animation offset keying’ dropbox. By default it’s on ‘absolute time’, bt you can change that to particle age or event age, and when you animate the scale op values they will be applied along the particle or event age :wink:

@Johnaatn - nice work man! I liked the complexity and the subtle elements, the splashes are neat. I think you could get the scale more correct, but it looks cool nevertheless :wink:

I managed to finally complete one of my larger projects. Writing implicit metaballs (purely raytrace, no triangle mesh involved). Few nice things about this is that it supports true 3D motionblur, requires very little ram and produces perfectly smooth surface, no meshing errors.

For now its available only for VRay.

(UI example, Motion blur + SSS) http://www.niksula.cs.hut.fi/~jylilamm/graphics/Metaballs_25.jpg

(Particle Flow + SSS) http://www.ylilammi.com/graphics/MilkCoral.jpg
(Same as above, animated) http://www.ylilammi.com/graphics/MilkCoral.mov

With just 2GB ram you can render metaball system containing 10 000 000 particles like here:

http://www.niksula.cs.hut.fi/~jylilamm/graphics/Metaballs_12.jpg
(You can see the development Metaballs_01 - Metaballs_25)

You can download version here (for VRay 1.50 SP3a): http://www.ylilammi.com/BerconMetaball/

I also made the source code available if somebody is intrested.

Wow that’s so impressive! Extremely brillint and generous for you to give it away man!


#4990

This one’s just awesome!


#4991

whoah bercon amazing!

Thanks man


#4992

wow …this looks great! Many many thanks to give it away.


#4993

Suppa Bercon, looks awesome.
Kiitos.


#4994

humm … I know how to animate the scale op… I just want to do the same with a script op, without keyframe. Got it?

Bercon this is great!! why Vray only? Will it be avilable for Mental Ray soon?
