like in my directory I have V4.2 under figures...then tennis shoes under figures...then casual dress under figures I click on each one to load them in the scene...
Then I go to my Poses folder and look at those files for the "MAT_casual dress" or something like that to load onto each object after selecting it in the SCENE tab....then I look for a pose...to add to the MAIN figure in this case V4.
After that I click on RENDER and set it up to render...
To save your render, you need to go to FILE>SAVE LAST RENDER>wherever you want to save it..
Let me work on it this week and I'll give you a picture tutorial...teehee...
it's been hectic here and so that's why I had a long response.
DAZ has content that you need to download as well, install that in your DAZ content directory...
Then you can start your renders..
keep in mind you have to load the OBJ file...usually housed under the directory in DAZ called FIGURES. Then you load the pose.....or PZ2 file for the Materials and textures.....
