Hi, I would expect to find that in the Content Library Tab. I am not familiar with that product so I cannot be certain but that is where I usually look for the third party items. Did you refresh the files using that refresh option from the right click menu list? I know there is an option to auto refresh but.... I usually close Studio and restart it if I add lots of non-DAZ items at once.

I have started to put all non-Daz3d items in a separate library and then add that library to the list of DAZ content libraries. I find that works best for me.
