@Tomyee: I would say in my own word I'm not a technical guy, and to add what Biscuit said

there is no systematical relation as : still render/static simulation and animation render/animation simulation or conforming/static simulation,... It wouldn't be fun!

• sometimes you need animation even for still render. Classic example: a seated Victoria, you need the animation to put correctly a floating dress between the chair and V4.

• I do only still render but I use both static and animation simulation depending of what clothe, the result of the conforming, the pose, the final scene,... and sometimes I use even both for the same clothe.

• For sure most of Poser dynamic clothe props (dress,...) must go through an animation but there can be exceptions : you want a render with the default T-Pose :-) or you have basic dynamic props (poncho for example) where a static simulation COULD work with the pose you have

• VWD works with conforming clothe (cr2), dynamic clothe made for Poser (pp2), imported object in Poser (obj), hair (hr2) so whatever the "poser scene origin".
