Default converting Subdiv to polys with the detail

Trying my hand at organic modeling, but now Iím stumped. How do you convert a subdivision to polygon without losing the detail on the model? Every time I try it turns into a poly structure without the definition on the model.( if that makes any sense )

Thats kinda tricky you want your poly surface to be as light in geometry as possible. Remeber the a low poly cage once coverted to sub-d is usally pretty smooth. The trick is working in the low poly cage to add detail but keeping the sub-d geomerty low once converted.

I have my settings for going back between the 2 set as

Subdiv to polygons:

I have vertices checked only. This setting allows to covernt back to polygons at its lowest geomerty.


Polygons to Subdiv:

just use defalt if need be you can up the base mesh from 1000

Ok so to see if I understand,I should stay between 1&2 detailing mode on sub-d's and just get the shape I like then convert it to polys from there and do the detailing in polygons?

also, if you done the detailing in subd, and still want to keep the changes in the polygon (except creases of course) you can select a higher level when you convert subd->poly. so select vertices as kurt suggested in settings, but instead of level 0, change to level 1 or higher. just be carefull that you cannot convert back to poly and subs repeatedly or you would make the geometry more and more complex with every step - if you leave at level 1. so by default it should be level 0 - and you can go back and forth from subd to poly and poly to subd and you always end up with the same thing (this works faster than working in poly proxy mode in subd). also note that converting level 1 verts is differant (if you worked on level 1 mode in subd) than converting level 0 verts and then smoothing in poly mode.

One more question? Can the Character be polys and nurbs or just one or the other? Like lets say the body polygons and the head subds?

it can be both. for binding i would suggest you bind to the polygon for the head, and then converting to subd with the the proxy option. so the binding to the poly will still work, and the subdiv will follow. you just need to make the poly not renderable and you are done ...

edit: oh if you bind more than one polygone to the same skeleton, just make sure that the touching verts have the same weight - so the character does not get holes when animating - of have the neck be longer so you dont see holes when you look in the shirt ... hope that made some sense
