We will be discussing a very use-full tool in 3Ds max, ignore backfacing. This feature can be found in the editable poly section of any object is ‘Ignore Back-Facing’. You are only able to use the ‘Ignore Back-Facing’ tool when you select one of the edit poly modes (edges, faces, etc).

So when you select edge mode, you can now click ignore back facing and make a selection over some of these edges.

Now immediately you might not be aware of what this has done to your selection. But if you look at the back, you can see that the back-facing/rear lines were not selected.

If you do the same thing with ‘Ignore Back-facing’ disabled, the back lines become selected, which may be unwanted and cause problems when modelling.

This can be even clearer when you enable ‘Wire Frame Override’ as all edges even from the back of the object are visible. 

Ultimately, it ignores any elements that are underneath the surface that you are selecting. This can be helpful when you are doing any type of modelling work in 3ds Max.

Hopefully you found this blog helpful and if you would like to see a more in depth video tutorial, it will be linked below.
