Just a suggestion for people that use blender.
I made my blind in blender, and there u can set them like u wish, export and import in daz3d
And if they have to be opened/closed, i just go back to blender, do what has to be done, open them (its supper easy to "rig" stuff in blender, well, it's not actually rigging, u just have the option to move them in a way like blinds move) and then i export that, import in daz3d, apply the same surface and u have a (longer) but still, easy way to do stuff like this.
I'm not saying this because it's easy, easiest is to download them or rig them in daz3d if u know how.
BUT u can do this with anything
blankets for one example. First i make a bed (or just a blanket and use already done bed)
and if i need to have them over the character, i export the character and bed and import it in blender
take the plane (same scale as your original blanket offcourse), animate it with cloth effect where i want it to be over the character (thats why i export it from daz3d), apply solidify or whatever effect u used for the blanket before, and export only the blanket. And i import that in daz3d and just apply the same surface.
It also remembers the exact position of the objects (when u export in daz3d and import to blender and back) so u dont even have to move the blanket in daz3d world.
This is not a good way for everything, but with some objects u might find this very useful, specially for blankets.
Since u have to rig them for daz3d and then u have mesh that works really bad in daz3d, so u need to apply a push modifier and other crap so it doesn't mesh in/out of the character and objects.
In blender it just falls over your character and bed perfectly.
