Hello

Is it possible to create a box and to write a text on one face in the editor ?

Are you after making some kind of button? If so something like this may help?

GUI.Button(Rect(bttnX, bttnY, bttnWidth, bttnHieght), “Hello World”);

Thank but in want, if possible, to write on a face of a mesh directly in the editor ( non via scripting)
Unity supply a GUI.textArea function, you can write a text in the editor
I wonder how to attach this editable area to a face of a cube

What you want is a Render-to-Texture feature. I’m not sure Unity support it out of the box, but I know Scaleform plugin does.

EDIT: Looks like Unity does too; Unity - Manual: Render Texture
