 Text3D will suspend while loading the font data. Text3D requires fonts in JSON format generated through [typeface.json](http://gero3.github.io/facetype.js), either as a path to a JSON file or a JSON object. If you face display issues try checking "Reverse font direction" in the typeface tool.
 
-Alternatively, the path can point to a font file of a type supported by [opentype.js](https://github.com/opentypejs/opentype.js) (for example OTF or TTF), in which case the conversion to the JSON format will be done automatically at load time.

-If the response from the URL is not a JSON, `THREE.TTFLoader` is used to try parsing the response as a standard font file.
-However, keep in mind that the on-the-fly conversion to the JSON format will impact the loading time.
