If you create a text variable then set the Instance Editable value to be true, you should be able to see it in the details panel. Then in your construction script, set the text renderer text to be that variable.
Hello,
I created dummy blueprint class with TextRenderer component, is possible to change text in TextRenderer component through editor? For example I will drag and drop that dummy class into world (I spawn it) and then I could change text of that TextRenderer component somewhere in Details window.
Thank you
