for the safe side, you could always add a prop for the text lol :P thats how i've been doing sigs lately, gets a better look IMO and for an animation clip, SO much less work :) quick cheap way, add a square prop, and create a transmap for shape and a texture for whatever text is to be said, pretty simple if too much time on your hands, model the text into it adda fancy border, etc, tada! lol
