Godot Version
4.6
Question
I’m following the Instancing tutorial and there is a Note:
You may notice you are unable to change the values of the PhysicsMaterial of the ball. This is because PhysicsMaterial is a resource, and needs to be made unique before you can edit it in a scene that is linking to its original scene. To make a resource unique for one instance, right-click on the Physics Material property in the Inspector and click Make Unique in the context menu.
I’m trying to use Make Unique to test this out, but the option is grayed out in my UI. Am I missing a step?

Your resource is already unique, since you can modify it’s values. No need to make it unique again. If you hover your mouse over the grey option, the engine will tell you that.

Found this thread after encountering the same issue. Seems like the tutorial note should be updated because it doesn’t reflect the reality. Is it possibly due to version differences? On opening the project it warned it was converting from 4.2 to 4.6.
Also hovering the mouse over greyed out Make Unique does not show anything for me. Am I supposed to see a tooltip?

I have the same issue. Also opened with 4.6.
Yes it says the resource is already unique, but i cannot change the values, unless i first click “New: PhysicsMaterial”
This is not about “getting it to work” but more about understanding for me…
This is perfectly normal behaviour. You need to create said resource to be able to modify it, otherwise you wouldn’t be modifying anything.
However, if the documentation says something incorrect, you can open an issue about it on GitHub. Although I imagine it has been reported already so it’s likely going to be fixed soon.
EDIT: Changed the link, thanks @gentlemanhal

Minor correction, if its a problem with the docs you should open an issue in the docs repo

OK it works for you, but I’m saying it doesn’t work on my machine. Linux Mint 22.3 with Cinnamon Desktop and Godot 4.6
I have tested this on 4 different machines with 4 different Operating systems
- It works on my main desktop running Fedora 43, I tested both normal and forced Wayland support, and both times the tooltip showed up correctly.
- It works on my Windows machine running Windows 11
- It works on my Macbook Air running MacOS 26.2
And I’ve also taken the opportunity to set up an older laptop and install Linux Mint 22.3 on it with the Cinnamon Desktop, and both the normal and the Wayland version of Godot displayed the tooltip as it’s shown on my screenshot.
My guess is that this issue is specific to your configuration, or you didn’t hold the mouse there long enough for the hint to appear, but what I posted still stands. Under all the major Operating Systems, this hint shows up.
