If you're experiencing difficulties assigning new shortcuts specifically within the Slate Material Editor in 3ds Max 2024, it could be a limitation or a bug within the software. Here are a few suggestions to try and resolve the issue:
1. Verify shortcut compatibility: Ensure that the keyboard shortcut you are trying to assign is not already assigned to another function within the Slate Material Editor. 3ds Max may prevent you from assigning the same shortcut to multiple commands.
2. Reset keyboard shortcuts: Resetting the keyboard shortcuts to their default settings might help resolve any conflicts or inconsistencies. You can do this by going to Customize > Customize User Interface > Keyboard tab > click on the Reset button. After resetting, try assigning the shortcuts again and see if the issue persists.
3. Check for updates or patches: Make sure you have the latest updates or patches installed for 3ds Max 2024. Autodesk often releases updates that address software bugs and known issues. Check the Autodesk website or the Autodesk Desktop App for any available updates.
4. Report the issue: If the problem persists even after trying the above steps, it's recommended to report the issue to Autodesk's support team or forums. Provide detailed information about the problem, including steps to reproduce it, and any error messages or unusual behaviors you encounter. This will help Autodesk investigate and potentially address the issue in future updates.
In the case of the "Show material in viewport" action not working, it could be a separate issue unrelated to shortcuts. Reporting it to Autodesk's support team or forums would also be beneficial in this case.
