Well I hope everyone had a great holiday season to put an nice end to this decade. I thought for my first post of the year I would show you all a neat little trick for getting Softimage ICE particle simulations into Maya!  There's a little example plug-in for Softimage 2010 that basically will allow you to write Softimage ICE particle simulations into Maya's PDC format.  By simply creating- and then overwriting an existing Maya cache, the particles will magically show up inside Maya! I recorded a quick little how-to video but I'll explain setting it up in writing too. Watch the video first, then read below to help you set it all up.

First you will need to install the plug-in for Softimage. Its a "unsupported" sdk example so you will find it in the sdk examples directory here:

C:\Softimage\Softimage_2010_SP1_x64\XSISDK\examples\workgroup\Addons\PDC_Export\Application\Plugins

(NOTE: this is the 64 bit path, if you're on 32 bit make sure you adjust the paths accordingly.

Now copy the file PDC_Exporter.64.dll or just PDC_Exporter.dll for 32 bit into this directory:
C:\Softimage\Softimage_2010_SP1_x64\Application\Plugins

Once you do that start Softimage and you should see the plug-in appear in the plug-in manager. Now just rename the default filename and path in the Softimage cache settings so that it will overwrite your particle cache. By default Maya will write the cache files here:

C:\Users\USERNAME\Documents\maya\projects\default\particles

That's it, now just create an ICE simulation and see if you can pass it into Maya!

I hope this helps, feel free to ask questions on the comments section if you run into any snags. Interop with the Autodesk product lineup is a big priority so you can expect this to get more robust and easier in the future.  Press full screen by the way when watching the video for best results.
Have fun!!
