I have the Gathering Storm II in case someone want to look at the specific rules or flavour. Basically it's based around the triunvirate of heroes surrounded by a mix of everything blend in together: craftworld aspect warriors, kabalites, wyches, incubi, wraiths and harlequins.
The heroes are difficult to model though unless some creative kitbash...
Additionally I've discovered this amazing model of an incubus more similar to his new fashion at facepunch:

with his corresponding klaive.
.dae files are meant to be a sort of exchange format which requires some importer for 3dsMax or Maya, blender etc. I got the Collada importer and I tested with another .dae file for 3ds max 2008 and it works. No problem with importing them I think.
