Basing on this example: http://www.gistechsolutions.com/leaflet/DEMO/sports/sports.html I would like to do the same in my case, however, my way is slightly different: Firstly I have made a major layer disabled, moving checkboxes to the sublayers: although only 1 sublayer is visible. My code looks as follows: var url = 'json/vm2.json'; // Here is the url path to my GeoJSON file, function getColor(Type){ //layer 2 Virgin Media return Type == 'Infill' ? 'yellow' : Type == 'MDU' ? 'orange' : 'orange'; } function style(feature) { if (feature.properties.Type === "MDU" && feature.properties.Post_Survey_Home_Count === "") return{ fillColor: '#d4a270', fillOpacity: '#d4a270', weight: 0.5 } if (feature.properties.Type === "Infill" && feature.properties.Post_Survey_Home_Count === "") return{ fillColor: '#efefa9', fillOpacity: '#efefa9', weight: 0.5 } else return { fillColor: getColor(feature.properties.Type), fillOpacity: 1, weight: 2, opacity: 0.75, //color: '#ffffff', //dashArray: '3' }; } var baseball; // Get GeoJSON data and create features. $.getJSON(url, function(data) { baseball = L.geoJson(data, { pointToLayer: function(feature, latlng) { return L.circleMarker(latlng, { radius:6, opacity: .5, //color: "#000", color:getColor(feature.properties.Type), fillColor: getColor(feature.properties.Type), fillOpacity: 0.8 }).bindTooltip(feature.properties.Owner); }, onEachFeature: function (feature, layer) { }, filter: function(feature, layer) { return (feature.properties.Type == "Infill" ); } }).addTo(map); //Note turned on to start map with Data, Checkbox has checked property. }); //2nd Layer in map var footballTeam; // Get GeoJSON data and create features. $.getJSON(url, function(data2) { footballTeam = L.geoJson(data2, { pointToLayer: function(feature, latlng) { return L.circleMarker(latlng, { radius:6, opacity: .5, //color: "#000", color:getColor(feature.properties.Type), fillColor: getColor(feature.properties.Type), fillOpacity: 0.8 }).bindTooltip(feature.properties.Owner); }, onEachFeature: function (feature, layer) { }, filter: function(feature, layer) { return (feature.properties.Type == "MDU" ); } }); }); // Handles the check boxes being turned on/off document.querySelector("input[name=infill]").addEventListener('change', function() { if(this.checked) map.addLayer(baseball) else map.removeLayer(baseball) if (clickmark != undefined) { //i.e. if it exists... //function all to remove the yellow select circle, could call function to clear table from here. map.removeLayer(clickmark); }; }) document.querySelector("input[name=mdu]").addEventListener('change', function() { if(this.checked) map.addLayer(footballTeam) else map.removeLayer(footballTeam) if (clickmark != undefined) { map.removeLayer(clickmark); }; }) I don't understand why only 1st layer is visible. How about another one? Both comes from url relating to the 1 GeoJSON file. The console says: Uncaught TypeError: Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'. at NewClass._updateContent (DivOverlay.js:173) at NewClass.update (DivOverlay.js:116) at NewClass.onAdd (DivOverlay.js:53) at NewClass.onAdd (Tooltip.js:71) at NewClass._layerAdd (Layer.js:110) at NewClass.whenReady (Map.js:1411) at NewClass.addLayer (Layer.js:172) at NewClass.openTooltip (Tooltip.js:221) at NewClass.openTooltip (Tooltip.js:340) at NewClass._openTooltip (Tooltip.js:406) Blockquote and consequently this: Uncaught TypeError: Cannot read property 'addEventListener' of null at (index):261 Blockquote At the end I would like to add my geoJSON sample: "type": "FeatureCollection", "features": [ { "type": "Feature", "properties": { "Owner": 51429, "Type": "MDU", "Status": "Completed and invoiced", "Ticket_ID": "VM/TIK/858952", "NBU": 51429, "Address": "Sir James Knott House, Broadway West", "Postcode": "TS10 5AZ", "Date_issued_from_VM": "Wednesday, July 31, 2019", "Asbestos_rep": "POST 2000", "Planner": "Steve Levett", "Surveyor": "Mick", "STATS_Applied_for_date": "Wednesday, July 17, 2019", "STATS_compleeted": "Tuesday, September 10, 2019", "ACTUAL_Internal_QC_Date": "", "VM_ECD_date": "", "Client_Home_Count": 11, "Post_Survey_Home_Count": 11, "General_notes": "", "Directory": "file://Z:\\\\Fixed Line\\\\Design & Build\\\\2.

I forked it, but preserving the alpha does not work. It seems to be 1.0 already. Here is how I tested that: At the start of the main routine of the shader I did this: vec4 orig = getColor(m_Texture, texCoord); vec3 color = orig.rgb; So now orig.a is alpha. Then the shader does some magic with the color vec and at the end I do this: ` gl_FragColor = vec4( orig.a, color.g , color.b, 0.5);` The image below is the result: and as you can see, red is always there. So it is save to say orig.a - the original alpha - is always 1.0f And to be complete: i did set the background to be transparent: ViewPort offView = renderManager.createPreView("OffscreenView", cam.clone()); offView.setClearFlags(false, true, true); offView.setBackgroundColor(new ColorRGBA(0, 0, 0, 0)); // Transparant! So, why does it give me alpha is 1.0?
