Every advantage has its disadvantages.

So using a solid modeler like Autodesk Inventor to make DAZ props comes with this one:

 

 

On the boundary between the glass and the wine the surface meshes are occupying the same space, and LUX tries to render them both. Clearly not what I wanted to happen.

I already knew I should remove the glass mesh where glass meets wine, but I didn't, just to see what would happen.  And now I know for sure I should.

 

But what would be an efficient and practical way to do that?

I cannot prevent those surfaces to be formed, they come with the conversion from solid to mesh, so I need to remove them afterwards.

Especially inside a closed shape like that decanter I wouldn't know how to  selectively remove the unwanted vertices in a simple way. I'll see what I can do using the masking possibilities in Zbrush, that's really the only way I can think of right now.

Any suggestions anyone?

Thanks in advance : )

Cheers!
