a quick question.. how to tell if physx is enabled on GPU? I often reach a stage of fiddling around where ticking the box on enable gpu has absolutely no effect, where some scenes it does. is there any easy way to tell that gpu is in uses?

You must get this message in script editor after first frame:

The funny thing is - in 2012.5 it's already accelerated

I was talking/joking about the well-advertised but apparently not-implemented
"CUDA Accelerated PhysX Rigid Bodies", obviously.
And the Bullet-node only does ICE RBD, or not?
:-\

Ya I get it. But now it's seems actually works. Not for the Phys-eX of course

Mr. Core,

If you where able to write a ICE node that can talk to the GPU, then doesnt that mean that GPU accelerated ICE nodes are also possible?

It is possible to implement probably anything that you can do in stand-alone apps, include OpenCL and cuda support and as a result - accelerated nodes. From the ICE node you can just call some functions which are located outside simage

I wonder if guys at Autodesk can do something like that and pass some of the stuff in ICE to the GPU... Guys at Fabric-Engine claim to have done it (and inside a web browser!!!) and they are (for the most part) ex-SI guys with a lot of ICE experience...

Who knows

hi mr.core
thanx a lot for ur great work
i have problem for install ur plugin. i have softimage xsi 2012 , i put the px_dlls in C:\Program Files\Autodesk\Softimage 2012\Application\bin and after that i run xsi and in pluginmanager / workgroups i connect application folder to xsi , when i want to open ur test scenes xsi show me an red error message the plugin is not installed .

can u help me please ?

thank u so much

You need to connect whole folder structure. That is, put everything that was in zip file in some folder, and connect this folder as workgroup.

Just guessing, but could it be, you haven't got the Microsoft Visual C++ 2010 Redistributable Package (x64) installed?

Is there anyone who doesn't have Arnold?

thanks, but I get this message:

' INFO : ICE PHYSX SPH: Succefully created PxWorld!

no mention of cuda , perhaps Ive managed to install the ICE compound but not the dll? I cant see the dll anywhere in the plugins

** EDIT *** UPDATE ***

ok I disabled the previous workgroup, downloaded again the archive, made a new waterfall FX workgroup and now I have 2 versions , one under Px2Si called PhysX simulate SPH and another under ICE PhysX - GigaCoreFX called PhysX simulate Fluid they are both the same compound although the Px2Si version has no execute node only outputs positions.

regardless of this , something seems to have worked - am now getting 60 fps with GPU enabled and reach only 20fps without and when enabled, have the message

' INFO : || CUDA Manager Is Obtained! Created PhysX World!

fantastic! :D
