Fix Missing Back face on 3Ds Max 2023

Problem I’m solving

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.

Solution

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

Installation

  • Download the script from the button above
  • Drag the script straight into the viewport
  • I also recommend closing 3Ds Max first to make it remember the settings.

Code [Maxscript]

NitrousGraphicsManager.DarkerEdgeOption = #off
