*dynamic stuff isn't popular to make

*In fact dynamic cloth is easier to make than conforming clothes because you have don't to do the whole process of grouping and rigging, and you don't have to worry about morphs.
But it's also more limited than conforming clothes. It's much harder to make rigid objects like belts and buckles.
English Bob has  some quick suits and quick dresses which are a good starting base mesh for making dynamic clothes, you just can adjust them in your popular modelling program perhaps they only need some subdividing to make them more "fluid" in the cloth room.

Here's the link BTW.

If this is too technical, just say so, I can explain more if you want.. If you just want to have some dynamic clothing, search for svdl, he has made some excellent cloth for V3 and V4.

Dynamic hair is another chapter. Although I've made several attempts to make some dynamic hair of my own, I still find it extremely difficult to get some acceptabel results. making skullcaps isn't difficult, but the styling in poser isn't easy at all.
It is easier to adjust some existing dynamic hair than to make your own. Adorana has made some excellent free dynamic hair for V3 and M3, which isn't too difficult to adjust for V4 and M4 or any other model. She has also  a lot of material settings for dynamic hair, just look in the freestuff area.

Finally: poser 8 rendering is optimised for dynamic hair, like others said, and I believe the cloth room has also been optimised  and runs much faster now. So to get the best result upgrading to poser 8 is advisable.

best regards,

Bopper.
