I'm typing this on my phone, so I don't have access to the console output, but when I include DrawText.fxh some errors are getting thrown. They mostly relate to indexing with non integers. For instance, I fixed one of the errors on this line by simply casting to int:
index = digits[int(index)];
Honestly, I am new to shaders and this file just confuses me. Would be good to have this working.
