Blender only shows TFF fonts, on all versions I've tried (Windows 10).
The problem: When you add text (add>text), and you go to the font modifier tab, attempt to change font, and navigate to system fonts, only TFF fonts show up (even if filter disabled). OTF fonts do not show up. All fonts are installed properly and show up in other programs (Maya, Photoshop, Illustrator, Absolutely Everything Else).
My personal workaround: I've been using maya for any text, and then exporting it as OBJ into blender.
Anyone know how to make blender support OTF fonts? Seems strange that maya supports this and blender doesn't.
