New to blender and babylon.js

[benoit-1842]

Hi everybody, I have an animation that works fine inside Blender. It's a bvh that use with a Makehuman model.  The problem:  I am able after several minutes to get a .babylon file.  But when I drag it to the Sandbox, I get an eternal spinning disk.  If somebody could help me, It's kind of a big project and I want to use blender and babylon.

Merci,

You have to drag'n'drop all file (meanint .babylon and textures files)

 

Did you add a camera to your scene?

[benoit-1842]

My avatar is working when there's no bone and animation, I suspect this is the problem and yes there's a camera....  

 

Merci de repondre,

Benoit

Benoit, can you place your blend file somewhere so I can download it and take a look at it? In a PM if you want.

 

Check out this thread - I used the same tools - MH and Blender.

 

And here she is - the Blue Lady

 

cheers, gryff

I don't know if it make a difference but I have used MakeWalk......

Thanx,

Benoit

I don't know if it make a difference but I have used MakeWalk

 

Benoit, I used MakeWalk for the Blue Lady (and MakeClothes for the dress) Should be no big deal.

I tried the link - but I have to "apply for access" which I have done. I assume you have to grant it somehow.

 

Et merci beaucoup pour les voeux.

This one should work......sorry about that and thanx for your help,

 

Merci,

Well Benoit I got the file TY.

 

And I took a look at it. First question I have is: what rig did you export from Make Human?

 

What I see is a very complex rig with both FK,  IK and various control bones. Below is a screen grab showing just the bones in the right foot selected. In the yellow box, Blender tells me that I have 9 of 263 (!!!) selected. (The big bone at the base of the foot is an IK bone)

 

When I export you figure and rig, it exports all the 263 bones as far as I can tell. An example:

 

{"name":"toe.L","index":254,"matrix":[1.0000,0.0000,0.0000,0.0000,-0.0000,0.8890,-0.4579,0.0000,-0.0000,0.4579,0.8890,0.0000,-0.0000,1.3150,-0.0000,1.0000],"parentBoneIndex":246,"animation": {"dataType":3,"framePerSecond":24,"keys":[{"frame":1,"values":[1.0000,0.0000,0.0000,0.0000,-0.0000,0.8890,-0.4579,0.0000,-0.0000,0.4579,0.8890,0.0000,-0.0000,1.3150,-0.0000,1.0000]},{"frame":250,"values":[1.0000,0.0000,0.0000,0.0000,-0.0000,0.8890,-0.4579,0.0000,-0.0000,0.4579,0.8890,0.0000,-0.0000,1.3150,-0.0000,1.0000]}],"loopBehavior":1,"name":"anim","property":"_matrix"}}

 

 

Note  the index 254 for bone named "toe.L"

 

It does not appear to be exporting the animation apart from a start and end frame.

 

cheers, gryff

I have just used makewalk.....  Maybe I don't have the right thing....  I have a .mhx file from make human and I load and retartget it in Blender....  Do you have a very basic model that I can see, something very generic so I can compare and Tweek

 

Merci beaucoup,

 

Benoit

[benoit-1842]

Yeahhhhh  I figured out that there's different option in makehuman (have a super complex rigging, or a basic one etc.....) and I was alway chosing none so I was having a super complex rigging.....  Now I just have 33 bones.... And still working on my model....

 

Thanx,

 

Benoit

[benoit-1842]

Now I am able to open my .babylon file in the sandbox but the animation isn't working....  My character is in t-pose without having the bvh file working....

 

Thanx,

 

Benoit

Benoit, You chose the "game rig" - with 33 bones - right?

 

Now I am able to open my .babylon file in the sandbox but the animation isn't working....  My character is in t-pose without having the bvh file working....

 

Do you have a server that you can use? If so  set up your babylon file as part of a web page that you can then browse to

 

Create a webpage by grabbing  the scene loading code from my Blue Lady example (the index.html). Then just change the name of the babylon file to your file and delete all the code that refers to the music (the howler.js stuff).

 

Should work.

 

cheers, gryff

[benoit-1842]

Can you do me a little step by step I am fairly new with that

 

Thanx...

 

Benoit and yes I have used the game rig

Benoit : tutorial here : Loading your.babylon file inside your page app  by David Catuhe (AKA Deltakosh who runs  this forum)

 

Build an HTML page from the two blocks of code you find on that page when you scroll down. Something like below:

<html xmlns="http://www.w3.org/1999/xhtml"><head>    <title>Using babylon.js - How to load a scene</title>    <script src ="../hand.js"></script>    <script src= "../babylon.1.14-beta.js"></script>    <style>        html, body {            width: 100%;            height: 100%;            padding: 0;            margin: 0;            overflow: hidden;        }        #renderCanvas {            width: 100%;            height: 100%;        }    </style></head><body>    <canvas id="renderCanvas"></canvas>    <script>    if (BABYLON.Engine.isSupported()) {        var canvas = document.getElementById("renderCanvas");        var engine = new BABYLON.Engine(canvas, true);        BABYLON.SceneLoader.Load("", "xxxxxxx.babylon", engine, function (newScene) {            // Wait for textures and shaders to be ready            newScene.executeWhenReady(function () {                            // Attach camera to canvas inputs                newScene.activeCamera.attachControl(canvas);                //code to play animation                    var skeleton = newScene.getSkeletonById(0);                    newScene.beginAnimation(skeleton, 1, 499, true, 1);                // Once the scene is loaded, just register a render loop to render it                engine.runRenderLoop(function() {                    newScene.render();                });            });        }, function (progress) {            // To do: give progress feedback to user        });    }</script>             </body></html> 

Change the xxxxxxx to the name of your babylon file. Make sure you add the two lines of code to play the animation. Then save as index html. Upload to your webserver and view in your browser.

 

 See the tutorial for more on  setting up the files.

 

Make sure that all scripts, images, and the babylon file are all in their proper folders.

 

cheers, gryff

But I think it will help me more if I could export directly from blender.... Is there something I am missing for exporting animation done with bvh....  Right now I have my model in a T-pose in the sandbox but he's not doing my bvh animation....

 

Thanx,

 

Benoit

The exporter can auto animate the rotation, position, & scaling of python sub-classes of FCurveAnimatable  : Mesh(all 3), Camera(no scaling), Light(only position).  I do not have a copy of the old, flat static class, legacy code on this machine, but I do not think it was dropped skeletal animation.  For .babylon files, enabling this may more than changing the exporter.

[zouarino]

I want to stop the animation but this code doesn't work
please help my.


var createScene = function () {
var scene = new BABYLON.Scene(engine);

var camera = new BABYLON.ArcRotateCamera("Camera", 3 * Math.PI / 2, Math.PI / 8, 50, BABYLON.Vector3.Zero(), scene);

camera.attachControl(canvas, false);

var light = new BABYLON.HemisphericLight("hemi", new BABYLON.Vector3(0, 1, 0), scene);

BABYLON.SceneLoader.ImportMesh("a", "scenes/", "ww.babylon", scene, function (newMeshes) {

newMeshes[0].position = BABYLON.Vector3.Zero();
newMeshes[0].autoAnimate = false;
newMeshes[0].autoAnimateLoop = false;



});




return scene;
}
