Png texture mask


Recommended Posts

(I've just realised I did use a png in 2D on canvas but black and white jpg would be nice 😋)

It would be very hard to make anything in PG as this is my problem!

I'm sure you will understand if I show you in 2D on canvas

   img = "grain with transparency.png";

                var grainCanvas = document.createElement("canvas");
                grainCanvas.width = img.naturalWidth;
                grainCanvas.height = img.naturalHeight;
                var grainContext = grainCanvas.getContext("2d");
                grainContext.drawImage(img, 0, 0);

                grainContext.globalCompositeOperation = 'source-in';
                grainContext.fillStyle = "grain colour";
                grainContext.fillRect(0, 0, grainCanvas.width, grainCanvas.height);

Then use this canvas as the texture for the material and let the diffuse show through under it.  (which is one solution but I would prefer not to make a canvas - just use Babylon textures)

Well I've tried! I've made the texture the same size as my bump texture but it seems like the cords are not the same or something? What's missing here?

Also I take it you have to set has Alpha to show the diffuseColor below?

     var texture = new BABYLON.DynamicTexture("slabOutsideTexture", { width: img.naturalWidth, height: img.naturalHeight }, scene);

   var context = texture.getContext();
            context.fillStyle = "white";
            context.fillRect(0, 0, img.naturalWidth, img.naturalHeight);
            context.drawImage(img, 0, 0);
