Hey @felixpalmer do you know if the carto tiles have 3D buildings? They look flat in this example compared to mapbox so it either isn't there, or the height property is named something other than height/min_height in the style

Edit: Found the property with maputnik, its renamed to

'fill-extrusion-base': ['get', 'render_min_height'],
'fill-extrusion-height': ['get', 'render_height']
