I have a QGIS project where I have created some nice styles using New Symbology. I would like to convert this to either SLD for use in GeoServer or CartoCSS for use in TileMill. I have tried saving the style as SLD directly from QGIS and a number of plugins, but I always get "New Symbology not supported
" or "<!--FeatureRendererV2 VectorFieldRenderer not implemented yet-->
".
I have also tried a number of plugins to convert the project/layer to tilemill or a mapserver project, but no dice.
Any help with this would be appreciated.
