Custom Fonts

I've loaded a font from memory and from a file, but when I try to rebuild the font atlas via `onPreRender`, it just breaks. It doesn't crash, but most of the text turns invisible and the console background is completely transparent. I also tried this:

Code:

fontAtlas = im.GetIO().Fonts
im.ImFontAtlas_AddFontFromFileTTF(fontAtlas, "ui/common/Cairo-Bold.ttf", 17)

But I get the same result, so I don't think the issue is the font itself.

It seems like the engine handles the fonts, and it only creates them once (just before ImGui is initialized).
Are you able to maybe expose a function for adding & building fonts? I couldn't find one for it, the only font functions seem to be the ones from ImGui.

Unless there's another way? I'll keep looking just in case, but please do let me know if there is a way to do this already. Thanks.

I came across this: IMGUI Settings (beamng.com) (Thanks to Zeit), and it looked quite promising. However, I then saw this:
I have tried putting the font in `myExtension/ui/common`, and the game does find it, but it doesn't add it to the font texture. Output:

I can get around this by putting the font in the game directory (ui/common), but that's obviously not what I want.
Is there a way to force a rebuild of it?
