Refer to the link below, for billboard enabled meshes, I added mouse pick event so the camera will target to the mesh which being clicked. However, after click on the mesh which BILLBOARDMODE_ALL is enabled, I got the following error. I'd be really appreciated if anyone can fix this issue. Thanks. https://www.babylonjs-playground.com/#9XBPW4#2 if (!m.actionManager){ m.actionManager = new BABYLON.ActionManager(scene); } var act = new BABYLON.ExecuteCodeAction( BABYLON.ActionManager.OnPickTrigger, pick ); m.actionManager.registerAction(act); function pick(evt){ var mesh = evt.meshUnderPointer; camera.setTarget(mesh); }

I am trying to add a 4th LOD that is a billboard, but I don't see anywhere on how to actually use a billboard... how to make a billboard with a texture... Like a tree image. Can anyone tell me how to create billboard meshes with a texture... is that just a mesh with NO geometry BUT it does have a texture???

Is billboard mode working? If so, can anyone explain what it's doing conceptually, and how I can use it for a standard billboard effect (where the mesh is something like a hit point bar or a text label, that you want to be drawn un-rotated)? I'm using it in what seems like the obvious way. http://www.babylonjs-playground.com/#UJEIL#0 But as shown, meshes rotate based on the relative vertical angle between them and the camera. Is something broken, or is that not how you're meant to use it?

I'm trying, using my own shader, to make a billboard using a predefined XZ plane mesh. to do so, i first build the necessary vector (into my own material) to pass to the shader, var cam = scene.activeCamera; var look = cam.position.subtract(mesh.position).normalize(); var view = scene.getViewMatrix(); var up = new BABYLON.Vector3(view.m[1], view.m[5], view.m[9]); var right = BABYLON.Vector3.Cross(up, look); this._effect.setMatrix(__world_str, world); this._effect.setMatrix(__worldViewProjection_str, world.multiply(scene.getTransformMatrix())); this._effect.setVector3(__upVector_str, up); this._effect.setVector3(__rightVector_str, right); this._effect.setVector3(__center_str, mesh.position); then use the values into the shader as : vec3 newp = center + (upVector * position.x) + (rightVector * position.z); vec4 outPosition = worldViewProjection * vec4(newp, 1.); gl_Position = outPosition; where center is the center of the billboard. I use an ArcRotateCamera. However, this is NOT render properly. The plane is ALWAYS facing the camera, which is good, BUT it strectch vertically when spining arround.. What i have missed ???

if a mesh is assigned a parent and if its billboard mode is set then it is positioned incorrectly see http://www.babylonjs-playground.com/#AL9LF#0 here we have a sphere and a plane plane parent is set to sphere uncomment line 31. line 31 sets billboard mode notice that plane moves to different location

Hello, just want to know if this behavior is expected: when you set a Billboard mode to a mesh with a parent then the child mesh won't inherit scaling: http://www.babylonjs-playground.com/#1JSXHW Is there any way to avoid that? (other than changing the scaling to the child too)
