Projection in source of raster

[GD-Aichi]

Mapbox supports no projections, but openlayers does. According to the specification of mapbox style, there is no parameter for a projection. The only possibility for raster would be the schema "tms", which mapbox did not implement properly.
Do you want to bring support for projection? And if so, maybe I can support you there.

I have no plans to add support for projections in ol-mapbox-style. If you need custom projections, use OpenLayers to set up your layers.

Hi @ahocevar,
Thank you for this great plugin. I am trying to set up the layer using OpenLayers, but still I can't get the vector tiles to render in the custom projection. See the code below:

proj4.defs(
  "EPSG:2163",
  "+proj=laea +lat_0=45 +lon_0=-100 +x_0=0 +y_0=0 +a=6370997 +b=6370997 +units=m +no_defs"
);

ol.proj.proj4.register(proj4);
var projection = ol.proj.get("EPSG:2163");

var layer = new ol.layer.VectorTile({
  declutter: true,
  source: new ol.source.VectorTile({
    attributions:
      '© <a href="https://www.mapbox.com/map-feedback/">Mapbox</a> ' +
      '© <a href="https://www.openstreetmap.org/copyright">' +
      "OpenStreetMap contributors</a>",
    format: new ol.format.MVT(),
    url:
      "https://maps.tilehosting.com/data/v3/{z}/{x}/{y}.pbf?key=" +
      openMapTilesKey
  })
});

fetch(
  "https://maps.tilehosting.com/styles/basic/style.json?key=" + openMapTilesKey
).then(function(response) {
  response.json().then(function(style) {
    olms.stylefunction(layer, style, "openmaptiles");
    new ol.Map({
      layers: [layer],
      target: "map",
      view: new ol.View({
        projection: projection,
        center: ol.proj.transform([8.23, 46.86], "EPSG:4326", "EPSG:2163"),
        zoom: 1
      })
    });
  });
});

Result:

Should look like this (Greenland should be smaller):

Do you have any hints?- What am I doing wrong?

This is not an ol-mapbox-style issue. I guess the tiles you are requesting from https://maps.tilehosting.com/data/v3/{z}/{x}/{y}.pbf?key= are not in the projection you are referring to as EPSG:2163. And OpenLayers does not reproject vector tiles.
