Make faces invisible

[Picklehead]

I have an irregular shape truncated pyramid as the image below.

It is created using a buffer geometry and I now need to add the option to make the top and base transparent in the same was as you can with say the Three cone geometry. I don’t want to remove the face just hide it.

Not sure what is the best approach, any help or suggestions would be great

any help or suggestions would be great

Place the top and the bottom faces at the beginning or at the end of the buffer, then use .setDrawRange to pick which of the faces to draw.
