Hello Jogase!
I have been having problems in saving correctly for DAZ Studio, despite having used the staff for DAZ support creating files for DAZ, I could not understand properly, you may not master English very well, I'm Brazilian :-(
I use the Google translator for this. Software technical terms are too complicated for me during translation. Have you tried importing the obj file contained in the zip file with name Tree_of_Fear?
When it is loaded, the file "duf", makes the object open properly.
Try this please let me know any problems I will try to send the zipped file to obj and textures only.
Regards!
Gendragon
