I've got an object that I'm using for a collision which I want to be invisible. I started off using this tutorial https://www.sidefx.com/docs/houdini/destruction/tutorials/intro_to_mbd_2.html [www.sidefx.com]

and I found that if I add a visibility node just before the hitter is packed, that it's invisible in ogl.

and much later found that it's quite visible in mantra.

Any recommendations for how I can make the hitter invisible to all renderers yet still have it work as a hitter?
