is the updated version, based on physx 3.2, so it supports now nvidia kepler GPUs ( tested on my GTX670 and fermi-based GT520 as well ), also added ability to delete particles.
As declared in the final 3.2 SDK version there is added support for triangle( actual ) shape for kinematic ( animated ) obstacles, but it still doesn't work and nvidia's devforum doesn't work as well (see here
), so I will ask why once they will restore it
The attached archive contains 4 DLLs, which you need to put in "C:\Program Files\Autodesk\Softimage 2012/3 XXX\Application\bin" and the physx workgroup which you need to connect through File->Plug-in Manager->Workgroups page->connect, after that you MUST restart xsi. This
also needs to be installed ( if you have si2013 skip this step since it already has installed this package).
If the wg has been installed successfully, in the same archive is placed xsi project with the sample scenes.
