Hi Guys,

Is there a way to disable Blend4Web console log warnings and errors? I would like to hide them for the production website.



Thanks

Thank you Roman!

It works

I have just realized that is written inside the documentation


It was in front of me and I didn't see it.

Thanks again.

I have created another test file from scratch.

The file test contains a plane.

I have assigned a material to the object and to the data




I have loaded it inside the script


I can see the object but I can't see the materials


I have created it with Blender 2.78c on Linux and I have exported it with the add-on 17.04.1

I'm really stuck there, I don't know what else to try.

You can find the files attached.

Hi Will,

thanks for the suggestion, but the code that I'm using is very minimal and it works with the stock files:
material_api.json
material_api.bin
(deploy/assets/code_snippets/material_api/)

I have also tried the same piece of code with others stock files and it works flawlessly.


I don't see the material list when I load a model made by me.

I have tested it with the standard Blender cube with a very simple material but blend4web doesn't return the material list.

Thanks

Hi Will,

thanks for the reply.

I have added a console.log for the object

and I can see the cube inside the console:


I don't know why you can't

I have also tried my code and the file that you have suggested (material_api.json)


and it works


So it is not the API call get_materials_names, but probably it is something inside the exporter or Blender.

Any Ideas?

Thanks

Hi guys,

I'm new with blend4web and I'm not 100% sure if it is a bug or not, but the command get_materials_names returns always an empty array, I have tried in different ways but I don't get the expected result.

I'm using Linux (Arch Linux)
I have tested it with:
Firefox 53.0.3 (64-bit) and Chromium 58.0.3029.110 (64-bit).

I have tried with blend4web 17.02.1 and 17.04.1
I have exported a cube (in json/bin) with 2 materials. I have made a simple script to load it inside the page and to read the materials, but it returns an empty array.

An example to replicate the problem:

HTML File:
<!DOCTYPE html>
<html>
<head>
    <script type="text/javascript" src="b4w.min.js"></script>
    <script type="text/javascript" src="main.js"></script>
    <style>
        body {
            margin: 0;
            overflow: hidden;
        }

        #container_id {
            position: absolute;
            width: 100%;
            height: 100%;
        }

    </style>
</head>

<body>
    <div id="container_id"></div>
</body>

</html>


Js file (main.js):
var app = b4w.require("app");
var data = b4w.require("data");
var scenes = b4w.require("scenes");
var material = b4w.require("material");

app.init({
	canvas_container_id: "container_id",
	physics_enabled: false,
	autoresize: true,
	callback: load_cb
});

function load_cb() {
    data.load("test.json", loaded_cb);
}

function loaded_cb() {
    app.enable_camera_controls();
    var cube = scenes.get_object_by_name("Cube");
    var material_list = material.get_materials_names(cube);
    console.log(material_list);
}


material_list is an empty array in Firefox


and Chromium


Attached you can find the entire example, with the blend, json and bin files.

Hi guys

first of all thanks for the help.

I'm stuck with the material list, I can't get it.

This:
var object = b4w_scenes.get_object_by_name('Zeta_0');
var material_list = b4w_materials.get_materials_names(object);
console.log(material_list);

returns an empty array but I have 3 materials assigned to Zeta_0, you can download my files here:
json: http://d1mr8g7ihxhxdy.cloudfront.net/0222d970708f9ec80886058e78a2343ba4805a19.json
bin: http://d1mr8g7ihxhxdy.cloudfront.net/0222d970708f9ec80886058e78a2343ba4805a19.bin

I have did a console.log of the b4w_scenes.get_object_by_name('Zeta_0'); and it seems ok, it is full of data.

Am I missing something? Reading the Json I can see the 3 materials assigned to the mesh:


Do I have to do check something inside Blender before the export?

Thanks again.

Reply to post of user Will Welker
I am sometimes wrong on this stuff so one of the developer can correct me if needed but…
I believe you can change the texture but not the material. You can change the properties of the material, see the Material API
You can change the texture to a different image, see the Change Image API

Thank you Will, I supposed that, but I wasn't sure.

I was also thinking to a different approach. If I assign 3 different materials (for example) to the same object. Do you think that it would be possible to hide show the materials?

Thanks
