Is it somehow possible to get the texture/material from the one circled in red and use it on the one circled in yellow?
I would like to cut the object, which unfortunately does not work with Fortnite objects.
in the editor you should be able to right-click the entry for the material in red, click copy, then paste it into the material slot for the other one:
Of course I have already tried this, but unfortunately it is not possible. I can press copy but it doesn’t copy here so I can’t press paste on the next one
Sorry, not to be insulting but just saw the question and thought it was an easy answer. I work in the ‘regular’ editor so unsure why the editor for Fortnight is not working.
What you can try is this:
The little folder icon with the arrow, 2nd in from the left on the material in the red circle. Click that and it ought to bring you to your content-browser with that item selected:
With that item selected in your content-browser, under the yellow-circled thing, click the first icon to add the currently-selected-item to the material slot:
Otherwise, you can just-browse to the item via the drop-down in the yellow-circle.
