  1. I am loading a mesh from a babylon file The mesh has a skeleton. The shadow casted by it is not proper. See file "with_skel.jpg" to check the shadow casted. Now if i remove the skeleton by doing mesh.skeleton=null; The shadow is proper. See file "without_skel.jpg" I was able to reproduce the issue in playground but wasn't able to save the code. I got the error message "file too big" when trying to save. The code is a little large as it has an embedded scene file. So I have attached the code here. See file "playground_code,txt" Copy the code to playground to check. comment on/off line 44 to see the issue playground_code.txt
  2. Realtime rigging

    Is it possible to place a t-shirt over a rigged human mesh and transfer skeleton and weights of human to the t-shirt in Babylon.js? So then you can animate the t-shirt with the human I know you can do all this in Blender, but I'm wondering if it could be done in real-time using Babylon.js
  3. Hi All! The BABYLON.Debug.SkeletonViewer help to view skeleton in array of lines. So can we create the bone from 2 points to build skeleton?
  4. Do anybody know if its possible to create a class Like InstancedMesh BUT use a separate skeleton... So I can either clone or build up a skeleton for each instancedMesh to use... that way each instanced mesh could play a separate animation... Don't know if its possible with the current InstancedMesh class but maybe can be re-write a class of subclass that can handle using a seperate skeleton... Maybe just wishful thinking Yo @Deltakosh do you think would be possible at all ???
  5. I am continuing my work on Particle Hair. I can transfer vertices without faces in Tower of Babel. See: Matrix weights / indices are not really capture-able, so I am just trying to generate them. If they need to be generated, might as well do it in Javascript vs Python and save the transfer bandwidth. I was not going to get real fancy with the number of influencers, just 1. As soon as I add the skeleton, the Hair (LinesMesh) dis-appears. I added both vertex colors & skeletons to LinesMesh for 3.0. I really wanted to get this working prior to 3.0 production. I could just be having a mental block, so I tried to do the simplest playground scene. If you change the if (1 === 0) to if(1 === 1), it also disappears. Any clues?
  6. I have a scene not quite ready, but essentially a human mesh appears. It does some skeleton posing coordinated with some morphing. The scene is using an arcrotate camera. The human has meshes for eyes, eyelashes, eye browse, teeth, & tongue which were all merged prior to export. They are a single mesh with multi-materials, so sub-meshes, in BJS. If you zoom in, the sub-meshes disappear early. I am not sure, is this was supposed to happen? BTW, If no animation is done or only the morphing, then this does not happen. If I do the QI.skeleton posing this results. The series of poses do lower the skeleton, which are part of a defense. Could it be since bones are done on gpu, frustrum is not done based on being slightly crouched? It does look really weird.
  7. Hi, What I am trying to do here is a bit too complex to simulate it in a playground. I hope i can explain it. I have a mesh that was build from raw vertices and polygon data. I have added the bones weights and indices. I am sure these two arrays are fine, they come from the same original model as the vertices and polygons. I have checked this too. // The code to add the indices and weights to the mesh base_model.mesh.setVerticesData(BABYLON.VertexBuffer.MatricesIndicesKind, base_model.bonesIndices, true); base_model.mesh.setVerticesData(BABYLON.VertexBuffer.MatricesWeightsKind, base_model.bonesWeights, true); I then load a skeleton - also from the same origin, so the bones indices match those in the indices array. The skeleton is attached to the mesh. When I rotate bone #0, the entire mesh rotates accordingly. No surprises there, and to me this is proof that the weights and indices are effective. when I scale the bones, parts of the body also scale. Now, when I rotate bone#1- upper leg -, nothing at all happens. And nor does rotating the other bones have any effect. //The rotation command I use: rig.bones[1].rotate(BABYLON.Axis.X, .01, BABYLON.Space.WORLD, base_model.mesh); screenshot #1: you can see the bone rotates, but the mesh does nothing. screenshot #2: this is the original model, that does rotate the leg with the bone. screenshot #3: rotating bone #0 rotates the entire model. I know I am doing something strange here, but I assure you it is necessary to the application I am working on. I hope any of you have some suggestions where to look for an answer.
  8. Hey there! Catacomb Chaos is an endless action arcade game where you try to survive against unrelenting waves of skeletons. You can loot gold and purchase potions for your next life. Let me know what you think! Play here: https://sambrosia.gitlab.io/catacomb-chaos/ I learned some neat stuff making this. Engine design, ECS, and steering behaviors are some of the cooler things I experimented with for the making of this game.
  9. Hi all, I've been wondering, a mesh like "the dude" seems to be using a single skeleton(so you only have to call beginAnimation Once), but he is made up of several meshes, When i export meshes to babylon, the "main" mesh is exported with the entire skeleton(all bones), and children meshes are each exported with their own version of the skeleton (containing only the bones that mesh use), So i have to call beginAnimation for each mesh/child mesh. If i point the child meshes skeletons to the main mesh's skeleton (mesh.skeleton = mainMesh.skeleton), which also contains the bones the child mesh uses, and then beginAnimation, the child mesh is either spagetti, or just not animated properly, So my question, How is it achieved to use the same skeleton? using 3DS Max 2016, exporter 0.8.0, (also tried an older exporter, same result) Cheers
  10. I made an example of how you can mimic a skeleton/bodyparts using LockConstraints in P2 physics. I thought it might be useful to share it/ add to the Phaser examples , for people looking for ways to use joints/ lock constraints in their game. here is the example: http://54.87.189.59/example3/ The sprites I used are from my own game, but you could very well replace it with any other sprites... In the code I also explained how it works.
  11. I was wondering if it's possible, and if yes, then how, to get more responsive movement when using getPositionToRef to attach a mesh to a bone assigned to some skeleton from an imported model. I think it's the same when using attachToBone. http://www.babylonjs-playground.com/#1N9CSW#2 The position and rotation of bone #6 (right hand) is used to position the sphere. Imagine it was a sword or a gun. Try moving the camera around, and notice the movement of the sphere. It seems to be a little behind, and not as crisp as one would have hoped for. Am I missing something here?
  12. Hi to all. There really isn't any issue here; as exporting animations to babylon from blender works fine, except for the "4 bone influencers per vertex" limitation. I understand that it is a browser thing: http://www.html5gamedevs.com/topic/10772-blender-export-issues/ http://www.html5gamedevs.com/topic/9560-rigging-rigify-blender-export-babylon/ My question is sort of strange, but I'll ask it anyways. I have no idea how to rig following this limitation in blender. How would one go about ensuring that this limit is not exceeded? Sure importing a MakeHUman model with the gaming rig, 32 bones I think, enabled would work, but when of the times when one is not rigging humanoid characters? Like sea monsters? Or giant insects? or something like that? And even if one is rigging a humanoid character, what of when the MH rig just doesn't do what you'd want and you have to do your own rig? So how would one make rigs ensuring that that limit is not exceeded? Any pointers on how to go about this would be appreciated. I also have one other question, would it possible to have babylon.js come with something like a visual editor for rigging? You import your static models and then rig them using it; it should guide the rigging process so that this "4 bone influencers per vertex" thing is not exceeded. (Please don't tell me to build it myself! ; at least not now!) Those are my questions. I attached a picture showing what happens when the limit is exceeded; the animation works but some areas are invisible. Other rigs I did did not show at all once exported to the .babylon format. Thanks in advance.
  13. This is an issue I've had with multiple models. http://www.babylonjs-playground.com/#4CVUS#2 See how some vertex or maybe a bone has points attached to the camera? The issue seems to be with the skeleton, as removing this and the skin modifier seems to remove the issue: http://www.babylonjs-playground.com/#4CVUS#3 I'm using 3Ds Max 2015 and the Babylon.js Exporter. When uploading the file to Claro.io, the mesh and skeleton are both intact, but exporting to .babylon somehow removes the skeleton aswell. As far as I know, Clara.io uses the Blender exporter, but that's no success either. I was just wondering if anyone else has had this issue, and if yes, then maybe know a fix or a way around. Attached is the .max file for reference. simple.max
  14. Here's the deal, I'm importing a model with skeleton, bones, animations etc. I assign the model (Index 0) and the skeleton (index 0) global variables. Then, outside of Babylon's native import function, I clone the model and the skeleton, and run animation (from frames) just fine. The problem is, when I try to manually manipulate bones using their getters and setters, somehow, rotating 1 bone from 1 clone of the original, also rotates the bones of all other clones, as well as the original. Changing the names and ID's of bones doesn't seem to help, either. Soo. Is there any way of cloning bones? no clone function exists, and I'm unsure of how to approach this. I'll see if I can create a simple PG, as the project is pretty complex by now. As I mentioned, I can run different animations on the different skeletons without any issues. But as soon as I manually rotate bones, all clones + original are all affected.
  15. Is it possible to show the skeleton/bones of an imported mesh? I don't mean lines and debugging layers, but actually rendering the bones themselves, so they won't stay hidden. Is this a possibility, or simply not a feature? PG example, because why not: http://www.babylonjs-playground.com/#1SJMJ0
  16. I'd like to be able to choose whether to use or ignore a skeleton, assuming ignoring a skeleton will improve the performance. (each bone reduces the performance as far as I understand, even when no animation is played) The purpose is to use the skeleton during the model's animation, and ignore it when no animation is played. Is such a thing possible? Will it improve the performance or is it already optimized in bjs core?
  17. In a blender scene one of the character meshes has an armature with an animation. After exporting to a .babylon file and loading it, if the character with the skeleton armature is visible when the scene starts , the animation plays and the scene works as normal, If the camera is facing away from the animated character when the scene starts this error occurs Uncaught TypeError: Failed to execute 'uniformMatrix4fv' on 'WebGLRenderingContext' : No function was found that matched the signature provided.(using nw.js based on Chromium 41.0.2272.76.) This is how the scene is loaded BABYLON.SceneLoader.Load("", "TheBlenderScene.babylon", engine, function (newScene) { newScene.executeWhenReady(function () {It's happened in 3 projects, my current workaround has been to include all the animated meshes in the view when the game starts. Has any one else has had this problem, or have an idea of how to avoid the error? thanks
  18. Hi, dear programmers! I am making a decal blood like in this example http://www.babylonjs-playground.com/#1BAPRM#81 All works fine if my mesh is static, but when my mesh is animating then the decal take first frame and that all. I set skeleton for the decal, but does not metter, decal don't animates. Like on the screenshot, the left pic is when I shooted and the right pic is one sec after the shot: How I can do implement an animating decals?
  19. Hello guys, I'm moving on with my scene and I got stuck on skeleton animations. I have situation when my soldier model is running and while running animation is playing (or any other animation) he is being hit. The results of such situation is that running animation is stopped and hit animation starts playing, while my model is still moving forwards. So I have few different options here: Stop model movement and continue run animation when hit animation finishes Blend two animations with different weights. I know that this is possible with Three.js' animation mixer but I could not get it to work with babylonjs is this even possible? Any other thoughts? I was going thought this forum but I only found topics on blending when one animation changes other animation.
  20. Hello guys! I have, maybe, a little bit strange question. But how can I set the main position of skeleton or the started position of skeleton I dont know how its named. When I export model from blender and current animation frame in blender let's say 35, in babylon, if I do not begin skeleton animation, skeleton current frame it is 35. If I export model from blender and current frame 12, than in babylon main pos of skeleton it is frame 12. How can I set main pos for skeleton programmatically in babylon. I need set main pos first frame regardless of current frame in blender. Becouse I often export from blender and I can foget set skeleton in first frame and it will not be immediately noticeable in the game. I hope you will understand about what I told
  21. Hello everyone! I'm working on a BabylonJS project and having problems with the movement of the 3D-model. I have used tens of hours to find a solution with poor results. The projects goal is to get 3D-model/avatar move according to the movement data from Kinect-sensor. I'm using a C#-server to send Kinect data through WebSocket to JS and BabylonJS for visualization. The problem what I'm having is that I don't know how to correctly move the model. BJS documentation seems to focus only to ready-made animations and not to the manual deforming of meshes with skeletons. I've moved and deformed the skeleton in BJS, but cannot get the meshes to move with the skeleton. Everything works fine in Blender (moving the skeleton deforms the mesh), but not in BJS. I've also tried to make custom animations for the skeleton in BJS to animate the model frame by frame with the data, but it's so complex I'm having a hard time understanding it (with no proper tutorial). What is the correct way to manually deform models with skeletons in BabylonJS? If the right way is to make custom animations can you help me understand how to build an animation for a skeleton in BJS? (I'm familiar with the BJS tutorials and documentations for animating meshes with no skeletons). My previous post about the problem Here is a bit creepy custom animation I'm working on. (How to delete the ready-made animation?) Here is one debug-model I'm using. How to make skeleton animation from scratch if your model doesn't have one? Thank you for your help. Mazax
  22. I have an imported, animated, rigged character mesh. I want to move its z position on keyboard input. I'm not seeing a position attribute on the Skeleton or on the Bones. I'm not seeing an obvious way to do this. playground at: http://babylonjs-playground.azurewebsites.net/#2F6AQS#2
  23. Hi, Is there a way to extract a bone's World position? I need an actor to pick up a rock and throw it. ELI5, please!
  24. I have a model loaded from a .babylon file, which consists of several meshes, a matching skeleton with animations is also loaded from that same file. I'd like to create a clone of the whole model (meshes + skeleton), and be able to animate each clone separately. I iterate over the meshes with a simple FOR loop and clone them, so far everything works as expected. I clone the skeleton, however when I try to animate the clone using scene.beginAnimation(skeleton...) neither the cloned meshes nor the original meshes are animated. When I try to animate the original skeleton, the original meshes are animated successfully. Since my skeleton cloning is completely separate from the meshes cloning, I guess it makes sense, as they don't have references of each other. 1) Is there a way to pass the skeleton which meshes it should be attached to after cloning? (or the other way around - pass the cloned skeleton to the cloned meshes) Alternatively - Is there some way to clone the meshes and skeleton in a way that keeps the newly cloned meshes synced to the newly cloned skeleton? 2) Is it even necessary to clone the skeletons if I want different clones of the same model to be animated separately? 3) Does a skeleton have a function similar to mesh.createInstance()? For instance, if I call mesh.createInstance(), should I still call skeleton.clone() or does skeleton have a function similar to createInstance() for improved performance?
  25. Hello everyone!I plan to use the Kinect v2 (that for xboxOne) to move an avatar in my scene.My idea was to gain the quaternions of jointOrientations and then change the appropriate bone matrix. Nevertheless, the jointOrientations are expressed in global rotations (each jointOrientation indicates the direction of the joint in absolute coordinates) while, if I understand it, I can only modify the local matrix of skeleton bone. So I am trying to convert local jointOrientation in local rotation:var joint; //the joint of kinectvar parent = joint.Parent();var localOrientation = BABYLON.Quaternion.Inverse(parent.Orientation).Multiply(joint.Orientation);But I'm having trouble in the transformation of the reference coordinate between kinect joints and avatar bones int the babylon scene... I tried to change the axes by swapping values (x, y, z), but I'm probably wrong var kinectOrientation; //orientation of the joint expressed in quaternionreturn new BABYLON.Quaternion(kinectOrientation.y, kinectOrientation.x, kinectOrientation.z, kinectOrientation.w); //this is just one example, I have tried in different casesDo you have any advice? Thanks in advance
