PhysX Fluid Simulation in Softimage ICE

[Mr.Core]

I'll post an update later (most likely after kepler releasing), I am currently sitting on the 7300GT so it's a quite difficult to debug physx on it

This really looks fantastic! Unfortunately I get the same issue as mamali132002 has. Scene loads, particles apear, but dont get any simulation going on. Under plugin manager, the .dll is marked as invalid as well :/

In any case though. Great work as it seems from above!

Has anyone got this working in Softimage 2012 SAP?

I have moved the dll into the correct folder as stated in the text document that comes with the download, also have the microsoft c++ installed although it's a newer version than the one that the download link points to.

I am also a little confused about where the workgroup is that I am meant to connect, can't find any workgroup folder within the download folder.

Any help would be super awesome, sorry if I am just been plain stupid here.

Thanks.

Alex.

If I recall correctly, you unRAR the archive, take the dll's out of there and use the folder you have just unRARred as the entry point of the workgroup...

Cool, thanks will try that tomorrow. Cheers for the help.

Brilliant, mr Core! Works on my GTX 460 (1 GB). Any news on next version? Mainly dynamic obstacle without convex hull restriction would be very nice. But thanks for this as it is!!

Tekano: how're you setting particle color like in your screencaps - looks like a gradient on velocity? I'm using a colorinfoswitch compound (got it from XSIbase user dubCUT) but not getting quite the same result.

Hi druite

think I just get particle speed > rescale to 0,1 > input onto a color gradient

simples!

Thanks for feedback, I will get back on it as soon as kepler ( gtx 680 ) will ship because I have no ability to test plugin in the gpu mode at this time, sorry

[Tekano]

you know Im tempted to ship out a GTX to you mr. Core, just until the 680 arrives

Hi druite

think I just get particle speed > rescale to 0,1 > input onto a color gradient

Yes, that's what I initially did, and it does sound simple... but all I get is a uniform color (somewhere on the gradient), as if all particles have the same speed. Where do you plug the color gradient in - I get nothing if i plug into the emitter 'color' input and the uniform color if I use a 'modify particle color' and plug it into a new port below the emitter.

That colorinfoswitch is nothing more than a prefab setup to easily switch between all sorts of input to drive color, but it's giving me the same result.

[Tekano]

oh ok will have a look into the scene later and post a compound - actually remembering now, I think the rescale was just plugged into the weight of a 'blend' color node rather than a gradient. so blending between blue and white. make sure that the particle speed is checked so you know how much to change the rescale amounts from

[Mr.Core]

>>Im tempted to ship out a GTX to you
Good news!

Did you solve velocity after plug-it into the gradient ? By default, physx compound doesnt set the velocity attribute, you need to do it manually by setting pointposition in custom attribute ( for ex: self.prev_pppos ) before the compound and subtracting it from the new pointpositions after the compound.

[druitre]

Thanks mr Core, that did the trick.

Are there more attributes obtainable this way? I'm looking for something that is called 'vorticity' in Realflow, it's used to get a foamy look.

"Vorticity is a mathematical concept used in fluid dynamics. It can be related to the amount of "circulation" or "rotation" (or more strictly, the local angular rate of rotation) in a fluid."

So, the places where there are little vortexes. Slightly different from rotational speed of individual particles, I guess.
