Where exactly are you looking? Anyway, let's go over the whole thing anyway ;)
As you probably know there are 2 panes which you can use to access your contents: the smart content pane as well as the content library pane. Thing is: assets which you grab from 3rd party websites such as Renderotica usually do not automatically show up in the smart contents pane. So... for those contents you need to look them up yourself within the content library pane.
This also means that you need to access the items using their official system locations. Poses for example are usually installed in "People\Genesis x\Poses" where 'x' refers to the Genesis generation number.
Next... also keep in mind that not every vendor provides a ready to extract "clean" product, sometimes other folders get in the way.
For example... generally used system folders for Daz Studio are: "data, People, Props, Runtime", but sometimes vendors provide these folders in a "layered" way. In other words: they're inside yet another folder. So instead of seeing these names you'd get "Library" or "My Library" and in there you'd then get "data, people, etc.". So if you were to extract such an archive as-is in your Daz Library your assets may end up in the wrong place.
I came across a few products from Layla myself (SKU #70682) and the "My Library" folder was definitely there... maybe food for thought?
Hope this can give you some ideas!
