I just tried DS3 again. It was installed when I installed DS4 a couple of weeks ago. After I did "File-Import" and after selecting the file, the "Obj Import Options" dialog box showed up but only showed two buttons: "Accept" and "Cancel". Turns out the box was minimized for some reason, so I used the mouse to pull the bottom edge of the dialog box to resize it. If you then select "Daz Studio" in the "From:" box, it will import with scale of 100% (or you can change that to 30% or whatever). Here's a screenshot with a stump imported and with the dialog box open. My stumps come in solid - but if you are inside the stump when it is too large, it will look hollow. Hope this helps.
