  1. I tried to import the obj file, and obj contained a number of posts, but in babylonjs, it seemed that each child's map was replaced with the last one. I looked at the console, and the network window shows these stickers loaded. Here's the demo: The correct effect should be: blender: threejs: babylonjs:(The wrong)
  2. Hi, I´m new to BJS and trying to get along with a 3D visualization for warehouses. The 2D visualization already work pretty well, the coordinates are stored in a DB running on a remote server. Target is to provide a library of rack elements (frames and beams) of different dimensions (height, width, length). I can provide a JSON from server-side Java-application with all the necessary data (rack id, rack type, coordinates, etc.) I´m using OBJFileLoader for importing obj and mtl which works fine as well. This is 2D visualization of a warehouse: Every blue rectangle is a warehouse rack consisting of two frames an a bunch of beam pairs: Both elements, frame and beam, come from separate obj-files. In the end of the day, i want to have something like this: The displayed meshes are kind of super simple, but perfect for playing around with BJS (i´ve all models in high poly as well). For some reason I can´t move (or change) meshes imported by this method: I can specify the mesh position while importing like this (works for the sphere btw.): var loader = new BABYLON.AssetsManager(scene); var pos = function(t){ t.loadedMeshes.forEach(function(m){ var meshName =; var meshID =; m.position.z = 5; m.position.x = 7; }); }; var steher1 = loader.addMeshTask("steher_2500_900_120", "", "http://localhost:8080/MagllanMain/Babylon/Cyril/", "steher_2500_900_120.obj"); steher1.onSuccess = pos; var sphere = BABYLON.Mesh.CreateSphere("sphere", 0.5, 0.5, scene); var simpleMaterial = new BABYLON.StandardMaterial("texture2", scene); simpleMaterial.diffuseColor = new BABYLON.Color3(0, 1, 0);//Green sphere.material=simpleMaterial; sphere.position.x = Math.floor((Math.random() * 2) ); sphere.position.y = Math.floor((Math.random() * 2) ); sphere.position.z=3; BABYLON.OBJFileLoader.OPTIMIZE_WITH_UV = true; loader.load(); // Begin of User interaction via button event $("#move_z").click(function(){ //scene.meshes.forEach(function(k) {alert(;}); pilot.position.z = pilot.position.z + 1; sphere.position.z = sphere.position.z + 0.4; scene.getMeshByName('steher_2500_900_120').position.z +=10; }); Funny thing is, i can move all other meshed via click-event. In general, I´ve been asking myself if I´m using the best way of doing this (import-method, file-types: obj and mtl). The workflow should be like this: 1) get JSON from server with an array of IDs and their coordinates (e.g.: ID="10012", ID_name="rack_012", ID_pos_x="130", ID_pos_y="120", etc.); 2) Importing the rack elements that belong to a specific ID into existing BJS scene; 3) Every rack element uses the same obj-file(s) (meshes) because all racks shall be of the same rack type, but with different IDs in BJS; I don´t know how to give imported meshes their own unique, custom IDs so that I can access them in the scene. More in general: I have my server-side array and i need a client-side array as well. When i change the position of let´s say 10 of 2000 racks in my layout / scene, I need to know which meshes i have to "move" on client-side. If there are any other weak points my way of trying to achieve this, please tell me. Any help appreciated !!! Topper
  3. Hi, I've some trouble though debugging so much..I have an obj/mtl file and the mesh and textutre is basically loading well, so far so good. But the texture (png) is an alpha image and this isn't transparent after loading. This is technically OK because there is no implementation inside objFileLoader for this case. I just want to set mesh.material.diffuseTexture.hasAlpha = true in the success-callbak of the ImportMesh-function , but the material isn't bound at this time. So, where to set "hasAlpha=true" , at which time is the material bound to the mesh? Thanks PS: I can enable it in the render loop (hack, because it's undeterminable how much frames I must wait), I also can activate hasAlpha with the DebugLayer manually BABYLON.SceneLoader.ImportMesh("", "blabla", "blabla.obj", scene, function (meshes) { var m = meshes[0]; m.material <== NOT AVAILABLE scene.getMaterialByName("Mat1"); <== scene.materials==empty }); scene.registerBeforeRender(function () { frame++; if (frame == 100) { var mbyname = demo.scene.getMaterialByName("Mat1"); <== OK , Material is bound to the mesh }
