glTF models for Skinning has orientation problem
I tried the loading of some of gltf models by babyon.js.
https://cx20.github.io/gltf-test/
However, Orientation of some of glTF models for Skinning is incorrect.
For example,
https://cx20.github.io/gltf-test/examples/babylonjs/index.html?model=RiggedSimple&scale=0.2
https://cx20.github.io/gltf-test/examples/babylonjs/index.html?model=RiggedFigure&scale=1
https://cx20.github.io/gltf-test/examples/babylonjs/index.html?model=CesiumMan&scale=1
Please confirm whether there is a problem.

Gamepad OnConnected Only Fired First Browser Seesion
The gamepad attachControl uses: new BABYLON.Gamepads((pad: BABYLON.Gamepad) => { this.onGamepadConnected(pad); });
but this.onGamepadConnected ONLY gets fired ONCE per browser session... If you refresh the page page it never gets fired thus the game pad no longer works... If i totally close down the browser and restart it works again because new instance of browser... What can we do about that???

You can see them pop up here www.punkoffice.com/dizingof
The result is that my mesh does not show. I don't know why its complaining about cross-origin because the image and mesh are all on the same domain.

serializing issue with BABYLON.ActionManager.OnIntersectionEnterTrigger
In a scene add an ActionManager to a mesh.
Register an action triggered by BABYLON.ActionManager.OnIntersectionEnterTrigger
serialize the scene
try to convert the serialized object to string
you will get the following error
"Line 46:28 - Converting circular structure to JSON"
see playground example
http://www.babylonjs-playground.com/#1UTZEV#10
if you comment out line 42
"sphere.actionManager.registerAction(action);"
then it works fine.
Please check

scene.onPointerDown and ActionManager issue
scene.onPointerDown and ActionManager do not work well with each other.
When an ActionManager is added to a mesh, the mesh becomes unpickable by the onPointerDown function
see playground example
http://www.babylonjs-playground.com/#1UTZEV#13
with lines 42 to 53 commented out everything works fine. The sphere is pickable.
Click the sphere and check the console message. It shows it was picked
un-comment only line 42.The sphere is no longer pickable.
un-comment line 42 to 47. sphere becomes pickable.
un-comment line 42 to 53. sphere becomes unpickable.
Please check.

CreateGroundFromHeightMap VERY SLOW movement
When using CreateGroundFromHeightmap... When i use the camera to move around on ground IS VERY SLOW and VERY CHOPPY... AND LOWERS FPS down to 15fps.
This is my code for creating Ground:
// Parse scene native mesh and heightmap terrains
var terrains:BABYLON.Mesh[] = this._scene.getMeshesByTags("[TERRAIN]");
if (terrains != null) {
terrains.forEach((terrain)=>{
console.log(terrain.metadata);
if (terrain.metadata != null && terrain.metadata.properties != null) {
if (terrain.metadata.properties.heightmapBase64) {
var tempBase64:string = terrain.metadata.properties.heightmapBase64;
var terrainWidth:number = terrain.metadata.properties.width;
var terrainLength:number = terrain.metadata.properties.length;
var terrainHeight:number = terrain.metadata.properties.height;
var minimumHeightLevel:number = terrain.metadata.properties.minimumHeightLevel;
var maximumHeightLevel:number = terrain.metadata.properties.maximumHeightLevel;
var groundTessellation:number = terrain.metadata.properties.groundTessellation;
var surfaceMaterialId:string = terrain.metadata.properties.surfaceMaterialId;
var surfaceMaterialInst:BABYLON.Material = null;
if (surfaceMaterialId != null && surfaceMaterialId !== "") {
var material:BABYLON.Material = this._scene.getMaterialByID(surfaceMaterialId);
surfaceMaterialInst = material;
}
BABYLON.MeshBuilder.CreateGroundFromHeightMap((terrain.name + "_Mesh"), tempBase64, {
width: terrainWidth,
height: terrainLength,
subdivisions: groundTessellation,
minHeight: minimumHeightLevel,
maxHeight: maximumHeightLevel,
updatable: true,
onReady: (mesh:BABYLON.Mesh) => {
mesh.parent = terrain;
mesh.scaling = terrain.scaling.clone();
mesh.position.x -= terrain.position.x;
mesh.position.z -= terrain.position.z;
mesh.checkCollisions = true;
if (surfaceMaterialInst != null) {
mesh.material = surfaceMaterialInst;
}
}
}, this._scene);
} else {
// TODO: Native Mesh - Note should try do all c# editor side

Any help would be awesome... as always

ArcRotateCamera strange behavior when beta near 0
When beta value is around 0, alpha values become a little bit erratic...
Test PG : http://www.babylonjs-playground.com/#NA4OQ#43
Move your mouse horizontally while trying to not move it too much up and down, and you'll see the bug. It looks like kind of a gimbal problem, but not fully...
This bug wasn't in BJS 2.4 and previous.

Babylonjs property option disappears on 3dmax dropdown
I think there might be a bug in the 3dmax exporter. The "babylon properties" option disappears permanently and gets rewritten as "file exporter" whenever I make my own workspace. To check this, I reinstalled the plugin and the "babylonjs properties" option was showing in the default workspace (as it should). I created a non default workspace and the "properties" option disappeared and changed to "file export" again. The option was irredeemable until the plugin was reinstalled.

SceneSerializer: rotation.asArray is not a function
Hello
I am trying to serialize the scene with
BABYLON.SceneSerializer.Serialize(scene)
and am getting a "mesh.rotation.asArray is not a function".
Serialization works fine when meshes are not rotated.
On further exploration, I realised that that mesh.rotation was not a Vector3 object but an object with getters, setters and __op__: Observer. Could this be the issue?
Can you please help me fix this.
Please let me know if you need more details.
Thank you

Bug? Vector2.PointInTriangle false on edge cases
Hi all,
Apparently points are not considered to be in a triangle when they are on the edges - is that "expected behavior"? It isn't to me...
BABYLON.Vector2.PointInTriangle(new BABYLON.Vector2(0, 0), new BABYLON.Vector2(0, 0), new BABYLON.Vector2(0, 1), new BABYLON.Vector2(1, 1))
Thanks

ArcRotateCamera target not being serialized ?
Are we no longer serializing ArcRotateCamera's target?
See playground example
http://www.babylonjs-playground.com/#I9AVT#1
line 29 sets the target
click the large box to serialize and reload the scene .
After the scene is loaded you will see the target is zero.
(Also notice the line mesh disappears on reload)

Position canvas on PG BABYLON.Analyser
Hello,
If use this :
var myAnalyser = new BABYLON.Analyser(scene);
BABYLON.Engine.audioEngine.connectToAnalyser(myAnalyser);
myAnalyser.drawDebugCanvas();
The frame is not positioned in the canvas :
http://www.babylonjs-playground.com/#PTV7W#8
And this causes a bug : ( connectToAnalyser is not a function )
var myAnalyser = new BABYLON.Analyser(scene);
music.connectToAnalyser(myAnalyser);
myAnalyser.drawDebugCanvas();

Bug highlightlayer + sprite transparency
Hi !
I noticed a bug with the hightlight layer and the sprite transparency, if the sprite overlapse the highlight object, the sprite take the color of the layer.
I tried to add the sprite to another renderingId but it was the same !
I attach a screen and a playground ( http://www.babylonjs-playground.com/#1UJAM6 ) to test !
Thanks for the answers !

ArcRotateCamera - Inertia dependend on FPS
Hello,
I don't know if this is something that could be merged into github but we had some projects (and therefore customers) that
were highly loaded with objects, thus a bit slow in rendering.
The camera inertia was then to long lasting to control the camera if you know what I mean.
This is what I've changed to handle this:
// Inertia
var engineDelta = Math.min(this.getEngine().deltaTime,100), inertiaFactor = Math.min(1,16.66666 / engineDelta);
if (this.inertialAlphaOffset !== 0 || this.inertialBetaOffset !== 0 || this.inertialRadiusOffset !== 0) {
this.alpha += (this.beta <= 0 ? -this.inertialAlphaOffset : this.inertialAlphaOffset) / inertiaFactor;
this.beta += this.inertialBetaOffset / inertiaFactor;
this.radius -= this.inertialRadiusOffset / inertiaFactor;
this.inertialAlphaOffset *= this.inertia * inertiaFactor;
this.inertialBetaOffset *= this.inertia * inertiaFactor;
this.inertialRadiusOffset *= this.inertia * inertiaFactor;
if (Math.abs(this.inertialAlphaOffset) < BABYLON.Engine.Epsilon)
this.inertialAlphaOffset = 0;
if (Math.abs(this.inertialBetaOffset) < BABYLON.Engine.Epsilon)
this.inertialBetaOffset = 0;
if (Math.abs(this.inertialRadiusOffset) < BABYLON.Engine.Epsilon)
this.inertialRadiusOffset = 0;
}
// Panning inertia
if (this.inertialPanningX !== 0 || this.inertialPanningY !== 0) {
if (!this._localDirection) {
this._localDirection = BABYLON.Vector3.Zero();
this._transformedDirection = BABYLON.Vector3.Zero();
}
this.inertialPanningX *= this.inertia * inertiaFactor;
this.inertialPanningY *= this.inertia * inertiaFactor;
if (Math.abs(this.inertialPanningX) < BABYLON.Engine.Epsilon)
this.inertialPanningX = 0;
if (Math.abs(this.inertialPanningY) < BABYLON.Engine.Epsilon)
this.inertialPanningY = 0;
this._localDirection.copyFromFloats(this.inertialPanningX / inertiaFactor, this.inertialPanningY / inertiaFactor, 0);
this._viewMatrix.invertToRef(this._cameraTransformMatrix);
BABYLON.Vector3.TransformNormalToRef(this._localDirection, this._cameraTransformMatrix, this._transformedDirection);
this.target.addInPlace(this._transformedDirection);
}
It rotates by the given inertia amount depending on the time that proceeded during the renderings.
The
var engineDelta = Math.min(this.getEngine().deltaTime,100)
is to avoid big camera jumps on frames that last longer than 100ms. In our project the render loop doesn't run continuesly.
If someone likes to test this and/or push it into babylon I would be glad to have contributed a small thing :-)
If not it's also completely okay as it's only needed in our project(s)! ;-)
Best regards
Kevin
