Good morning Roman
I'm trying out the example of canvas textures, such as I recommend you recommend. My goal would be to be able to write text over the texture of the selected object.

The problem I have is that it does not find the texture in the object. The mapping is done using UV mapping, I do not know if it is the correct technique that the API understands.

I attach the image of a texture on blender:

I am using the latest version of blender and blend4web

mi file.js have this function:


function cambia_texto2(){
	
	 var cubo = m_scenes.get_object_by_name("Cubo");
	 var ctx_image = m_tex.get_canvas_ctx(cubo, "mitext");
	 //var ctx_image = m_tex.get_canvas_texture_context();
	 console.log(ctx_image);
	

   if (ctx_image) {
        var img = new Image();
        img.src = APP_ASSETS_PATH + "matrix-texture2.png";
        //img.src = "matrix-texture2.png";
        img.onload = function() {
            ctx_image.drawImage(img, 0, 0, ctx_image.canvas.width, ctx_image.canvas.height);
            ctx_image.fillStyle = "rgba(255,0,0,255)";
            ctx_image.font = "350px Arial";
            ctx_image.fillText("Hello, World!", 300, 300);
            m_tex.update_canvas_ctx(cubo, "mitext");
        }
    }

}

Mi index.html

<div id="main_canvas_container"></div>
