Is there a cheaper option than Reiss that allows you to take in rigged Poser figures, or pre-created poses and animations from Poser into Max? The other parts are icing on a cake, and may be better achieved within Max itself.
I just purchased Pomax, available here on rendo. Rigging translation has a lot to be desired, but character poses and morphs and animation sequences come in rather decently! Not bad for about 1/4 of the price of the other. Maps come in too. I haven't tried procedurals.

Don't be mislead by the 'animation' import with pomax though, it doesn't bring in a keyframed functioning rig, it brings in a morpher sequence.
I was bummed because their marketplace ad didn't clarify how the animation comes across, but if someone wants to bring in unrigged, posed character and some morphs into Max, it works pretty slick.

And I second what was said about cloth and hair sims being better off done in max from scratch. Much more robust then in Poser.
