[Qgis-user] How to apply own styles to custom vector tiles?

[Saber Razmjooei]

Hi Jukka,

Unfortunately, there seems to be an issue with the conversion. I have tried
it with https://github.com/wonder-sk/mapbox2qgis which is the basis for the
Maptiler plugin and our first attempt while adding the native support for
vector tile.
To solve your issue and in general a better way of handling the style
to/from Mapbox, I suggest to resolve this ticket:
https://github.com/qgis/QGIS/issues/37152

If you'd be interested in sponsoring the fix, let us know.

Kind regards
Saber
