Yes I concluded the only way to do this was via C++, as Slate can still use bitmap / offline fonts. That said I don’t know C++ and so hadn’t decided what to do about that yet.
It’s a shame that plugin isn’t available as that does seem to solve the problem. It says compatible with 4.24 too, so clearly someone is updating it / maintaining the description?
Very frustrating all around. The best interim solution I have is to use a 3d widget render and try to force the resolution down, mixed with nearest-neighbor filtering, it gives a good enough ‘retro’ look. But it still requires styling the font with font materials, which isn’t ideal.
