Issue

This problem started when I started upgrading to 3Ds Max 2023. I have this problem where whenever I’m entering a Sub-object level like adjusting vertices in an Editable-Poly object, the edge of back-facing polygons are disappeared.

Cause

Someone in Autodesk decided that we should darken the edge a little bit when it’s the back-facing side. This is somehow already working without the new feature enabled, which is called

DarkerEdgeOption

Solution

Use the script in the download link to disable the option.

How to use:

I recommend having all 3Ds Max windows closed down. Drag the script and drop it into the viewport. I also recommend closing 3Ds Max first to make it remember the settings.

Description:

The entire script is just simply turning off the Darker Edge Option in Nitrous Graphic Manager.

NitrousGraphicsManager.DarkerEdgeOption = #off
