Hi 
I just happened to stumble across something on Denis Pontonnier´s Website. Here is the link:
http://dpont.pagesperso-orange.fr/plugins/MDD_Pointer.html
A bit further down the page for the PlugIn it says:
"
[font=Arial][size=-1]Particle Scan , for baking LW Particle System,
exports in LW ‘pfx’, ‘mdd’ and ‘mcc’(per frame) format, ,
‘mdd’ format included particle size and life infos.[/size][/font]
"
*.mdd´s could be brought in to 3dsMax by using PointOven
Or maybe even with a newer incarnation of pointCache2, he mentions a “PointCache2_R6”
and also provides a link.
Sounds interesting enough but I have not tried what he describes, though…
Will try to find the time to check when I have access to Max at work next week.
Hope it helps ;-]
Cheers,
