  1. How can I add a Texture to the following sample https://www.babylonjs-playground.com/#4GBWI5 I tried the following code: mat = new BABYLON.StandardMaterial("", scene); mat.diffuseTexture = new BABYLON.Texture("textures/texture.jpg", scene); // mat.diffuseColor = new BABYLON.Color3(1, 1, 1); //mat.diffuseTexture.hasAlpha = true; build.material = mat; I get the following error: .WebGL-0x7f8fa201c400]GL ERROR :GL_INVALID_OPERATION : glDrawElements: attempt to access out of range vertices in attribute 1
  2. My idea is to "project" a cubic texture from a given point as Google Streetview or Matterport do? The idea is that this kind of shader should look like projected texture not like reflection as CUBIC_MODE does. I've made several test like using refraction with IOR (it looks promising!) but the projection is always done from camera position. Any tip on this? Thank you in advance!
  3. Hello, I am using babylonjs to implement a 3D visualizations inside my app. The app allows a user to define a scene in a 2D view. The scene is static in the 3D view - meshes cannot be moved, edited etc. A user can interact with objects using mouse - selection by click, hover on mouse move, double click to open in another view. In my opinion the most natural way to present that something is happening when user moves mouse is to change meshes’ colors. Everything works well (50-60 fps) when there isn't much meshes – 300-400. Unfortunately, performance drops down when the scene becomes m
  4. Hi, I'm taking a rather big bite here since I haven't really used TypeScript before, and I have very limited experience with JS and node in general. So I'm not really sure where the fault lies, but I'm pretty sure it's something stupid easy. The problem I have is this: Uncaught TypeError: Cannot read property '_environmentBRDFTexture' of undefined at Function.e.GetEnvironmentBRDFTexture (babylon.js:1) at t [as constructor] (babylon.js:1) at t [as constructor] (babylon.js:1) at new t (babylon.js:1) at t.Creation.createMaterial (Creation.ts:28) This error appears
  5. Hi, I'm trying to reproduce ocean shader like this one: https://jbouny.github.io/fft-ocean/#day I know we have waterMaterial in Babylon (which is gorgeous!) but not quite what I'm after: it only works with windForce/windDirection which looks like you're constantly moving or as if water is constantly flowing. I've tried to use shader which you can find at https://github.com/jbouny/fft-ocean but it's just waaaay over my head! First of all, I can't figure out how to split it into vertex/fragment shaders to use in Babylon. Any shader/GLSL gurus out there, any help hugely appreci
  6. Is it possible to set the bump height of a standard material like on the water material? Thanks, Pichou
  7. Hi, How I can color the mesh backface only, the mesh maybe has a texture or not. Thanks in advance.
  8. While importing meshes designed in software like Autocad and Blender, I noticed that the color of a previously imported mesh is getting applied to many meshes that are later imported. Then I realized that that this is due to conflicting material IDs. Is there a way to modify material ID of an imported mesh or is there any other solution to this problem?
  9. I love BABYLON , I encounter a troble about waterMaterial.It often appear some black edges at some angle of camera. I can't find what cause it. lights: there are two lights ,hem and point. but the waterMaterial still black when I adjust the lights camera: arcRotate,target is (0,0,0),and the bigger the beta ,the darker the water renderList:[skybox]
  10. Hi everybody ! I'm importing .obj files in my application, and I want to change their color. However, the color seems to be changed when the page is loading, but when it's finally loaded the mesh still has its basic grey material (so while the whole scene is loading we can see the mesh being pink for half a second and then takes back its basic color/texture/material). I've seen something about UV maps etc.. but I checked it in Blender and it is activated when I import into obj. Here's a pg trying to reproduce my problem ( first you will need to help me importing my ob
  11. I was unable to transform mesh instance if the original mesh had a shader material. Is this a bug? I have created a playground example using box mesh. If you open the debug -> mesh panel, you realize there are 6 meshes, but only 5 are displayed. This is because one of the instances in the second row was not transformed properly. On the other hand, clones of meshes with shader material can be transformed properly. https://playground.babylonjs.com/#B2NZ1M#1
  12. I'm glad I discovered babylonjs. I'm testing on different browsers and I have a color rendering problem with the stable version and FireFox only. Normally we should see a red sphere and a green sphere. ■ SandBox : https://www.babylonjs-playground.com/indexstable#ZM9G4E#3 ■ Demonstration Video : Thank you for your help and bravo for this framework.
  13. HI everybody! Is it possible to add a rim effect on mesh like in this image : Thanks, Pichou
  14. Hello, No bug, no issue today ! I was just wondering about the choice of linking materialDefines to subMeshes, rather than directly on materials themselves. Does that mean that two subMeshes could have the same material, but different defines ? As the material updates the defines depending on its own properties (not the properties of the subMesh), I can hardly see how it's possible. I would love to see an example of this if you have one. I mean, I'm missing something. I'm quite sure this choice has been made for a good reason. But I don't get why. Thanks for you
  15. Are vertex colors and materials compatible? I've created a playground based on the custom mesh playground to illustrate the issue: http://www.babylonjs-playground.com/#VKBJN#160. If no material is attached, I get an interpolation of the colors over the triangle. If the material is attached to the mesh in line 42 the triangle is black and it appears to use only the colors of the material. My ultimate goal is to use a point cloud with vertex colors and a material. Thanks, Jess
  16. Hi everyone, I know it's possible and advised to use InstancedMesh when several meshes share the same geometry and the same material. Is there some recommended optimization to do when two meshes share the same geometry but have different materials ? For example with this case : http://playground.babylonjs.com/#T4Z2V9#1 (here VertexData object is already loaded) Is there something better than two calls to "applyToMesh" ? Like obj1.geometry = obj2.geometry, this kind of thing... (my question is based on the fact that Unity explicitly share the same geometry across
  17. Hello, I'd would like access to any mesh through my loader for change a texture map , but the log output 2 times the same model : https://bin.fuelphp.com/snippet/view/OJ Is it my script which run 2 times or what version I should use ?
  18. I'm using BabylonJS V3 with Blender 2.79 to create product visualizations. Many times, it is necessary for me to define more complex shaders in the JS code. I'm using lines like scene.meshes[1].material.emissiveColor = new BABYLON.Color3(1, 0, 0); to define the shaders after export. Usually every mesh can get it's own shader this way. Unfortunately, I can't get it to work somehow. Even in small test scenes (one red icosphere, one green cube, a hemi lamp and a camera), both objects get the same material. When trying to change the appearance like shown above, both meshes change color.
  19. Hello, It has been a while I did not introduced a new feature in BJS so as the higlight layer was famous, let s introduce the glow layer: http://www.babylonjs.com/demos/glowlayer/ Documentation is available here: https://doc.babylonjs.com/how_to/glow_layer
  20. Hello folks, i try load an .obj file and modify the material/texture scaling. Loading goes well, but not scaling of the textures When i try to access the material object i get a undefined error. meshes[0].material is undefined, in the screen shot you can see the property is there. I dont know what i do wrong // first param: ["myMesh1", "myMesh2"] // https://doc.babylonjs.com/how_to/load_from_any_file_type BABYLON.SceneLoader.ImportMesh("", "./assets/temp/house/", "restaurant.obj", game.scene, function (meshes, particleSystems, skeletons) { // do somet
  21. Hi all, I want to ask about StandartMaterial, if I add to material a ambientColor or a diffuseColor or a specularColor it means that this colors mix with material.texture colors in every frame, or just at once and then new colors saves somewhere in buffer. Need to know this for performance, if all colors mixes every frame I think this bad for performance and I will be find some other ways. Thanks : )
  22. Hey everyone! Is there a way to add a smooth transition when changing the material of a mesh? Thanks, Pichou
  23. Hi, Is it possible to control image format export for 3d max materials (force jpg, png for example) somehow? As for physics material (pbr) it produces png right now for me even without any transparency. Thank you in advance.
  24. hi, anyone knows why changing the value of "pointSize" doesn't influence the size of points of a shaderMaterial? shaderMaterial.pointsCloud = true; shaderMaterial.pointSize = 10;
  25. Hey everyone, I have something weird happening with the game I develop. See in this test page : http://test.wazana.io/ ( it is a special preview for you! ) The materials of the units and buildings are flashing. I observed this behavior only on chrome (working normal on IE, Edge and Mozilla) and not on all computers I tested (maybe there is a problem with a specific version of chrome). I use BABYLON.MultiMaterial on units and buildings because they always have 2 colors so one material for each color. But when it flashes on Chrome, this is either one color or the other on the entire mes
