Glad to hear. In terms of font rendering, there is a paper from VALVE (2007) describing their font rendering back then. Unfortunately, the BGE never got that far as you may probably know. See 1, 2 or 3 for BGE text issues/options.
But fonts are just one way of using distance fields, that’s why I wanted to keep the thread generic. If you e.g. ask google for “distance field robotics” you’ll find more examples based on different motivation.
