At SIG SoftImage showed a group of 6Mio Polygon models animated with reasonable performance on a 32Bit system… So… yes… with 5.x you can pose your 2.2 Mio Mesh. HOWEVER, you will need to max ot your Memory (32 Bit = 4GB on board).

PS:With the 64Bit system I did some REALLY insane renders.
PPS:Yes Tez. But if your Geometry is ok, then you can paint the weights in XSI in ‘realtime’. I animated a Bird and to fine tune the mesh was not a big deal. If you have the Essentials Version, then you can also use ‘GATOR’ to transfer a lot of information from one mesh to a completely different mesh. THAT saves time. Check out GATOR at the Softimage Website.
