    I'm trying to figure out a way to have a graphic block with a portion of it cut out based on user added text.  Something similar to the attached image.  I've done several basic alpha mattes using a quad to mask of text, images, etc. but have not been able to find a way to create this effect.  In After Effects it's a pretty simple alpha inverted matte and you're off.

    Any suggestions anyone might have would be greatly appreciated!  Thank you.

    Finally one that I can answer.  The step you are probably missing is having both your quad and the text box inside of a layer object.  Once that is done, on your scene font that you are using, select it, go to Edit Material.  Then towards the bottom of that new window select subtractive in the blending mode.

    If you want to get super crazy, you can use visual logic to set the height and width of the quad based off of the size of your text box.  That way the quad will scale with the text (for the most part).

    Visual Logic.  Boundingbox.height of text box goes to the quad height.  Boundingbox.width of the text object goes into the width of the quad.  I went ahead and added an add block and added a value to the width so that way I could create more space on the outside, depending on how much was needed.

    Thanks! I will give it a shot.  Makes complete sense seeing it in writing.
