polygon - Rendering non-simplified Mapbox Vector Tile using mapbox gl js -

i trying render mvt (mapbox vector tile) containing osm data using mapbox gl js, keep getting ugly polygons simplified (like in simplification section of documentation!). don't want polygons simplified. @ least best resolution close possible reality.

first, checked if come osm data. osm data good. looked tile server , more precisely mvt encoder (code). extent value, controls how detailed coordinates encoded in vector tile, 4096. 4096 value. don't understand why don't proper polygons.

i suppose issue comes mapbox gl js might perform additional simplification.

what extent value use in encoder? there way configure resolution mapbox gl js ?

i appreciate ! thanks!

mapbox gl js not additional simplification on vector tile sources. if seeing simplified geometries, done during vector tile generation.
