after you press "Okay" it will generate the text under your cursor, uisng the material you have selected. example: i select DMND, press Ctrl+T, type in "Hello World!", select the 7px font and press okay. it will generate the text under my cursor, using DMND, in the 7px font.
its called texter, you can find it in the script manager (if you have it), you also have to download the default fonts for it from script manager too, else it wont work, and to start it press Ctrl+T
So um, can you tell where to find this text generator you used?
