3DS Max 2025 The Menu System

[dev1SNH6A]

Hi Does anyone tried the new Menu Editor in 3ds Max 2025?

I tried the demo code it creates the menu in the menu editor but it doesn't show in the main menu.

This is the demo code for standard menu. when I run it this is what I get 

As you can see it doesn't show it here even I put the script in startup.

Thank you in advance.

Having the script in startup results in the script being run too late. The #cuiregistermenus has already occurred. It occurs between steps 3 and 4 of the startup sequence shown in https://help.autodesk.com/view/MAXDEV/2025/ENU/?guid=GUID-615D14FB-0F2D-4801-B381-1128C4128C70.

While not optimal, you could add to the end of your script:

(
local iCuiMenuMgr = maxops.GetICuiMenuMgr()
iCuiMenuMgr.LoadConfiguration (iCuiMenuMgr.GetCurrentConfiguration())
)

That causes the menu manager to reload the current configuration, causing the menu file chain to be loaded and the callback to occur. 

If you are also adding quad menus, similar code would be added getting the quad menu manager

(
local iCuiQuadMenuMgr = maxOps.GetICuiQuadMenuMgr()
iCuiQuadMenuMgr.LoadConfiguration (iCuiQuadMenuMgr.GetCurrentConfiguration()
)
