Select object in vilewport bug? 3ds max 2025

[infoTP6WE]

When I want to select an object, I can almost always click an object behind it. It's like ignoring the faces of an object closer to the camera. The whole selection is completely random, but I usually succeed in wireframe mode, but only if I find it very difficult to find an edge that it lets me click and does not see part of an object behind it...

Version 2025, there were no such problems than before (2020-2024).

That's something I see now and again too, then I don't see it for awhile. It might related to some other function that just hinders it temporarily. I know that didn't give you a solution. 

Have you reported it officially using the links Hagen provides in the top of the main 3ds Max Forum? The more of us who report it the more likely it gets on a "defect" list to be looked at.

Something in MAXScript to try:

nitrousgraphicsmanager.HardwareHitTestEnabled=true

or the opposite

nitrousgraphicsmanager.HardwareHitTestEnabled=false

That's a great little piece of code to keep in a "Handy Max Code" text document somewhere. Thanks Martin.

amazing, it works the way it used to! thank you very much for your help!!

Glad to hear this is helpful.

Just keep in mind that there might be other side effects if using hardware hit testing or not, especially with regards to selecting non-mesh objects (cameras, helpers, lights etc.).

Hello,

I appreciate the code. But this is a bizarre bug to be kept. Our productivity slowed down a lot because of this.
Is there a way max25 loads the "nitrousgraphicsmanager.HardwareHitTestEnabled=true" code by default? It resets everytime i start max

Tks

This is forum is mostly user-user and not so much an "Autodesk support" forum, so you need to use the official channels to contact support and provide feedback.

As mentioned before, there are downsides to always have hardware hit testing enabled, so maybe this is not the best idea - but yes, you can place the code in a startup script.

Confirming that this worked in max 2026. This needed to be run on a new install, so note to developers that this may be mistakenly disabled by default, causing a lot of headaches, and should be addressed.
