Hidden Polygon MaxScript?

J0NNYquid

Hey guys, I'm working on a massive piece of machinery for my work. I've got tons and tons of railings, stairs, panels, etc. The bottoms of all the railings will be hidden by the body of the machine itself. I've gone through and deleted most of the bottom and obscured polygons as I've gone along, but there are still a lot left.

My question is if anyone here has heard of a MaxScript that can identify when a polygon is hidden/within another object, and will allow me to select it for deletion. Any help is appreciated, thanks guys.

isnt automated but you could do an ao bake and then delete any polygons that show up completely black in your bake.

good question. OBJ export sometimes spits "you have a rat's nest" error messages, so there must be a way to check for hidden polygons at least.

Sounds like you're basically asking for a boolean to me.

You could try PolyVis. It's an old script, but it does what you want. I just downloaded it and tested it on a bunch of overlapping boxes (Max 2011). Still works.
