Cant Duplicate (Ctrl w)/Copy Paste any node in Materials Editor

When I create a node (any node) and try to Ctrl+w or copy paste, nothing seems to happen. I do not get a copy of that node but when I Ctrl+z, the display in the lower right corner say “undo: Material Editor: Paste”. I am using a PC. Any help would be greatly appreciated.

Using Unreal Engine 4.4.3

It works for me on a variety of versions of ue4.
And it should work.

You could go to “Advanced settings > editor preferences > Keyboard shortcuts > Common Commands” and see if the controls are set properly, if not press “Reset to defaults” or edit them manually.

Keep in mind, the copy can skip a bit to the right when “Ctrl + w” is pressed, or when you “Paste” it might be close from where your last mouseclick was.

Hey brad1100,

I have had this happen to me as well, and it was because I was not completely inside of the Material Editor itself. Make sure your active panel is the Material Editor and the last click was on the node you wish to copy.

Try this and if you are still experiencing your issue please let us know and we will investigate further!

Thanks,

Tried that (unchecked and rechecked boxes) still no luck.

Sorry for late reply (working and finishing CS degree). So I tried that with no luck. Here is what I did:

  1. Clicked on Material Editor Tab (also tried clicking on grid)
  2. Clicked on the node
  3. Clicked Ctrl+w (screen flashed but no new node was created)
  4. Clicked Ctrl+z (displayed “Undo: Material Editor: Paste”)
  5. Clicked Ctrl+c (while node was highlighted)
  6. Clicked Ctrl+v (nothing happened, not even a screen flash)

Any other suggestions would be well appreciated.
Tried on two versions: 4.4.3 & 4.5.1

Hmm… I know its a bit “out there” but… a reinstall maybe?

Are you using a source build from GitHub or are you running the engine from binary i.e. the Launcher?

tried that, did not work :frowning:

I am running the engine from binary.

Would you mind sending a copy of your dxdiag?

Also are you working on a laptop or a desktop machine?

Having a very similar issue. Started in BLueprint editor in 4.7 couldnt copy/paste but now in main editor window as well .

I should be very specific… I can copy/paste but the result is an empty object with the copied mesh no attached.

Hey IronTaxi,

Your issue seems to be related, but I need some further information and clarification as to where exactly you are copying and pasting to and from?

If you could provide me with some simple steps to reproduce the issue you are experiencing in a new blank project we can begin finding the appropriate solution.

Thanks,

Mine works fine in old versions of the Engine, but all of a sudden it doesn’t work in 4.20…
