This link, which describes how to do it on a Mac, was actually more helpful:

• http://hype3d.com/better-daz-studio-renders-with-mcjteleblender2-and-blender-on-the-mac/

First, you’ll need to grab the script from the mcjTeleblender2 script page.

Unzip this file in your Daz Studio content folder. On a typical Windows PC that’s C:\program Files\Daz\Studio\Content

The content was in a “mcasual” directory. I put mine at: C:\Users\dan\AppData\Roaming\DAZ 3D\Studio4\scripts

After installation, there is a one-time setup, which is to “Scan known directories for files…” which is available on a menu on the left side.

From within Daz3D (I have 4.8), with a scene visible, you run this script by doing this:

• Open the scene
• On the lower left, click the tab “Content Library”
• Type “teleblend” in the search window
• Double-click mcjTeleBlender3

This creates an OBJ file and materials in the directory you specify within the panel.

Running the mcjTeleBlender3 panel in Dax3D is supposed to create the Blender version, and then cause Blender to open with the content.

There is a Blender plug in, and I installed that, but I don't think it is activated.
