FX filters not working on glass

Hi everyone, I have a problem regarding glass materials.
I need to enhance the contouring lines of the glass part in the product I’m rendering, so i went ahead and applied the Line light FX filter.
This filter (and all the similar ones for that matter, like Normal, Heavy and Hidden line) doesn’t work on glass materials.
Is there any way I can solve this by changing a particular setting?

Thank you
