" but by exporting the model at base resolution and not higher resolution "
Keeping the polycount identical is mandatory for morphing only.
Here the OP wants to create drool / saliva onto the Genesis skin. Genesis that will later be rendered WITH subdivision.
So it's better to sculpt any prop close to the skin with a 65K polys at least version of the Genesis (Subdivided once) rather than the Base 16.5K polygons with too angular curves to model anything properly.
So let me reiterate : export the Genesis with subdivisions made in DAZ in order to 3D model/sculpt your saliva as precisely as possible (with Zbrush, Blender, whatever) especially if it's drooling along the skin for example.

Indeed
Without light everything would be pitch black.
My way of doing cumshots, saliva, drool, etc. You can find my work on Pixiv. My nickname is : CGI-CutiePie. Or the uncensored versions on AlltheFallen forums.
Warning : what I do with DAZ is not for all audiences. Anyway, for the tech part :
- I render once the whole image as clean and definitive as possible. With 0 cum, drool, saliva, etc.
- Then I Spot Render regions with body fluids, and with a very whitish unrealistic shader.
- Then I eventually Spot Render those same regions with another shader, more translucid, more shiny, etc.
- Now I have in Photoshop the main render with no fluids. And I have two layers, one with thick sticky fluid, and one with thin translucid fluid.
- Then with an XP-Pen, Wacom, etc. I use Photoshop's Layer Masks to nicely let appear parts of each layer that I want visible. I can easily hide excess fluids as the main layer is the image without any.
BIG advantage of this method : Iray does not allow (only 3D rendering engine in the world...) to specify which objects have to be excluded from shadow casting. So even a very translucid drool will generate an ugly very dark shadow. With 2 or more layers in photoshop, and the main layer without drool, it becomes possible also to remove all shadows casted by the body fluids.
This way, for cumshots or drool, I'm able to get pretty good results. All shapes are sculpted in ZBrush. And all textures are Iray Shaders with a bit of Photoshop extra work at the end.
