Converting DAZ textures to other packages

Doc Acme

I'm looking for information or even a utility,in order to export or otherwise reconstruct Daz textures that are multi layered for use in a different app.

I've been fairly successful converting some scenes and items into Lightwave via FBX export.  This gets you most of the way but textures only come over as a standard material, no PBR support, so there's some manual work needed.

For most surfaces this has been pretty straight forward, but I've come across an item in Stomemason's "Streets of the Wild West" where the terrain object has multiple layers using weight map images.  Unfortunately, these add'l layers are simply named Layer1, Layer2, etc.

Any way to find out what these correspond to short of just contacting Stonemason?
