Ok so I found the files but FontDescriptions.xml is in 0.0.0.107 and FonResolutions.xml is in 0.0.0.91 does it matter that they are in two completely different folders? Because I tried to follow the tutorial and my numbers just disappear.
EDIT: Ok I figured it out. This still works. I was not changing everything that needed to be changed.
Heres how to do it.
Follow all the steps, then make sure you change the numbers to however large you want like shown (this is in the font description file)
(( <Font Name="Heal" Type="RegularBold" Resolution="100_4_Auto" >
<Display Color="38,240,38,255" OutlineColor="35,35,35,255"/> ))
now in the FontResolutions, edit the numbers shown in bold
(( <FontResolution Name="100_4_Auto" AutoScale="true">
<Resolution ScreenHeight="1080" FontSize="100" OutlineSize="4"/> ))
make sure you edit those numbers that are in bold, they all have to be the same for this to work, hope this helps
