Would you have a secret tip that you could share with us?
Only thing is, if I share it, then it will no longer be a secret! 
The hardest part is trying to get them to sign a model release form. Sigh!

It seems all the people models need to have their texture maps re-applied. I can only guess whoever did the original 3DS conversions didn't check the output results for successful conversion.
Some of the people models don't even have any texture maps, while others the body parts have been merged and UV mapping is lost. It is quite a mixed bag, almost like a lucky dip!
I have also made some slight modifications to some of the ones I have downloaded and/or removed items from their original downloaded model scene.

Edit:
Forgot to mention.
I am also trying to learn DAZ studio, so I will have even more control, allowing different poses.
