@Nodragem you can open the console and open a new tab. you will see an entry that a new player joined, but that's all it does in the live demo, I think.

I can confirm that it doesn't work anymore. I saw the following errors in my console: VM72 ec2d630ffa49fdb7e8f1337b92361b9e67169777.js:1725 GET https://babylonjs-api2.azurewebsites.net/snippets/8BYZ34/0 500 (Internal Server Error) checkHash @ VM72 ec2d630ffa49fdb7e8f1337b92361b9e67169777.js:1725 run @ VM72 ec2d630ffa49fdb7e8f1337b92361b9e67169777.js:1734 (anonymous) @ VM72 ec2d630ffa49fdb7e8f1337b92361b9e67169777.js:1797 t._invokeFactory @ VM59 loader.js:1 t.complete @ VM59 loader.js:1 s._onModuleComplete @ VM59 loader.js:1 s._onModuleComplete @ VM59 loader.js:1 s._onModuleComplete @ VM59 loader.js:1 s._onModuleComplete @ VM59 loader.js:1 s._onModuleComplete @ VM59 loader.js:1 s._onModuleComplete @ VM59 loader.js:1 s._onModuleComplete @ VM59 loader.js:1 s._onModuleComplete @ VM59 loader.js:1 s._resolve @ VM59 loader.js:1 s.defineModule @ VM59 loader.js:1 o @ VM59 loader.js:1 (anonymous) @ VM108 editor.main.js:7 t._invokeFactory @ VM59 loader.js:1 t.complete @ VM59 loader.js:1 s._onModuleComplete @ VM59 loader.js:1 s._onModuleComplete @ VM59 loader.js:1 s._resolve @ VM59 loader.js:1 s.defineModule @ VM59 loader.js:1 o @ VM59 loader.js:1 (anonymous) @ VM109 editor.main.nls.js:7 VM72 ec2d630ffa49fdb7e8f1337b92361b9e67169777.js:803 Uncaught TypeError: scripts[(index - 1)].trim is not a function at loadScriptFromIndex (VM72 ec2d630ffa49fdb7e8f1337b92361b9e67169777.js:803) at XMLHttpRequest.xmlHttp.onreadystatechange (VM72 ec2d630ffa49fdb7e8f1337b92361b9e67169777.js:1713)

Here the fixed version (setPivotMatrix with the new optional parameter postMultiplyPivotMatrix set to false) of the example that JohnK mentioned: http://playground.babylonjs.com/#191SVM#12 And here my fixed playground, with no more need for negative angle: https://www.babylonjs-playground.com/#1RWE59#134 @JohnK I compared the two playgrounds and realized I had used the wrong order when calculating the cross product. Thanks for the hint!

Remember the fun we had with particles back then: Maybe you could use the 2D particles and control them to cover the model using the vertext data... I mean we had a cool möbius strip (http://www.babylonjs-playground.com/#2KOEWJ#9) back then so placing them statically on some fixed positions should also be possible, right?

Dang, somehow I still can't get it to work: https://www.babylonjs-playground.com/#1RWE59#131 It's always off. Any idea what I am doing wrong? Edit: happens with the original playground, too, if I change the values: https://www.babylonjs-playground.com/#1RWE59#132 Edit 2: Never mind, I think I got it now: https://www.babylonjs-playground.com/#1RWE59#133 Seems like the calculation of the angle was not quite correct. I now use acos of the dot product and then the negative angle. I have no idea if that's really correct, but it passed my tests var angle = Math.acos(BABYLON.Vector3.Dot(v1, v2)); cylinder.rotationQuaternion = BABYLON.Quaternion.RotationAxis(axis, -angle); I read something about the arc cos here http://www.euclideanspace.com/maths/algebra/vectors/angleBetween/index.htm, and then did the rest by some old fashioned trail and error. Let me know if I did it wrong and just got lucky somehow Edit 3: that those things look like penises is totally unintended!

I see I see, so a fixed bug it, thanks alot for the quick reply guys!

Hey guys, long time no see! I have been pretty busy and didn't have time to have fun with BabylonJS, but I had an idea that I wanted to try out. Therefor I need to connect two points with a cylinder, just as described in this thread, but for some reason all the playgrounds seem broken. I remember it worked just fine back then but now the cylinder is always off and doesn't connect the sphere (here for example: http://www.babylonjs-playground.com/#1RWE59#12). Anybody got an idea whats causing the behavior? Is it a bug, a fixed bug or a feature? And even more important: how do I get the desired result nowadays? Hope somebody can help, thanks in advance!

A playground would be nice. I would love to see how you use vertex transparency to implement Fog of War. I thought about how to do it a while ago bit didn't have a good idea yet. I wanna see how you do it. Splitting the mesh in submeshes might be easy: 'You can speed things up by subdividing your mesh into submeshes using mesh.subdivide(x) where x is the number of submeshes you want.' (source: https://doc.babylonjs.com/how_to/optimizing_your_scene_with_octrees#optimizing-collisions-and-picking) ... but not sure if submeshes work with those Occlusion Queries.

Looks cool, good job! I really like the graphic style!

Awesome! Thats really huge! (as DK likes to say) Especially the self-shadowing, that has been bugging me for a while! I have to try that out as soon as possible! (*feeling*excited*)

Awesome! Updated one of my old playgrounds right away to try things out and found it right away with the new search (search performance is really good, too!)

I don't think you can prevent the user from moving the point... would be horrible if java script was allowed to do that, right?

Seems like you can specify a renderingGroupID: http://babylonjs-playground.com/#272WI1#79 (found here: https://github.com/BabylonJS/Babylon.js/blob/0e1d4095b2e99b833f0a6f664e8495dbbf69f65d/dist/babylon.2.5.canvas2d.d.ts#L660)

Looking good again, thanks for the quick fix!

@JimmyBuchman I am not sure what you mean by layer by layer... like that: http://www.babylonjs-playground.com/#XALW2#13 -> click spheres (has a bug, sometimes if you click them in the wrong order it draws a wrong connection)
