[postgis-users] PostGIS mapbox vector tiles and custom tile grid

I'm trying to use PostGIS (ST_AsMVTGeom, ST_AsMVT) to generate mapbox
vectortiles for OpenLayers (512x512 tile grid). But I'm getting
oversimplified geometries for many zoom levels.

Looks like I can't use those PostGIS functions for custom projections
(custom tile grid), different from web-mercator. Sometimes I use raw
3D-model data without any wellknown coord system. What can I do? I use C#
for backend.
