I use EPSG:3857 projection for View in Map. I can easily add OSM to my map. When I use EPSG:3395 projection for View, I can easily add tile-layer with source in EPSG:3395(world mercator) projection.
But how to combaine on map tile-layers with different source projection(3857 and 3395) ? Is it possible in openlayers-3 ? Thanx!
