Note that when it is said in the same Runtime, that DS content does not go in the Runtime folder (though some of the support files like Textures will go in Runtimetextures) but in the folder at the same level as Runtime. For example you will have, inside your Content Folder folders named People, Data, Props, Runtime, etc. 

 

In DS you will likely map both the Content Directory (as Base Content) and the Runtime Folder (as Poser Content) in the Content Library Tab.

 

Also note that if this is not the same folder your Poser Runtime is in, then the Runtime folder in the Content Directory also needs to be mapped in Poser for the DSON files to work Poser.

 

I hope that is fairly clear. LOL
