Can i Backface cull walls?

Anonymous — Wed, 04 Sep 2019 07:19:52 GMT

Hi everyone,

I'm wondering if I can backface AEC Extended objects and specifically the walls. My work forces me to use the Walls and it's annoying navigating the walls without the backface cull that I can get when I use boxes. so is there a way to backface walls or have a function that would make navigating interior walls easily?

Thanks!

Hello @Anonymous ;

Apply Normal Modifier on walls, make sure Flip Normals option is active, then you can use Backface Culling as you do with Box objects.

@kgokhangurbuz I've tried flipping the normals on the walls, it didn't work. I don't know what version of max you're using that it works for you. I'm using a 2020 version.

Hello @Anonymous ;

You did not apply Normals on the walls, you applied Normal on a Polygon of a wall. Turn of Polygon Subselection from the 1st level of your modifier stack and re-try please.

I made some test walls and applied the flipped normal then clicked on backface cull, I have attached a screenshot. and if I just apply the normal without backface cull nothing happens.

Hello @Anonymous ;

I'm sorry for late reply.

You can convert your Wall object to an editable poly and flip the inner parts of your wall to avoid this.
