    Fading mesh color on edges

    Turns out the issue was me not exporting UV maps from blender.

    Fading mesh color on edges

    I have a mesh, that I would like to colour in a way, that the colour fades out near the edges. The sandbox: https://codesandbox.io/s/zw63povrz4 My current approach uses canvas, to first draw the color texture and then drawing an opacity layer that will fade the colour out. Expected result: https://i.imgur.com/YUCicAf.png My questions: Is there an easier method to do this. In my current approach The texture does not fit on the mesh, which means the mesh does not show any fading out, as can be seen in canvas on the side. How can that be fixed?
  3. If someone also gets > this._light.needCube is not a function It's because you are using a HemisphericLight, would probably be good to add this information in docs

    [SOLVED] Asynchronous scene loading not working

    Nevermind I am just stupid, if you look at createScene method, i was adding a second camera, even if one was already inside of the scene I am importing. That's the reason it was not showing anything
  5. Code: https://pastebin.com/zE0zhn7K So if you try to load a scene asynchronously, do something else, start the engine using that scene, The scene will just show an empty space. However, if you take a look at the code above, go to async function createScene(config) { const { textureModifier } = config; const { height, width, color } = config; const scene = new Scene(config.engine); await importScene(config.mesh, scene); And comment 'importScene' line, the go to async function run() { // await importScene(config.mesh, scene.internal); engine.runRenderLoop(() => scene.render()); // engine.runRenderLoop(() => console.log('test')); } And uncomment 'importScene' here, it works fine. I've included a .babylon file below. foot.babylon

    Importing mesh to scene from an object

    Okay, it turns out, that loader only accepts string type. So I can just do loader.load(scene, JSON.stringify(data))
  7. I have a .babylon file that I've read.And I need to load the mesh into the scene. What would be the best way to do it? I can't use HTTP requests, it has to import from that object. I've tried: const loader = BABYLON.SceneLoader.GetPluginForExtension('babylon'); loader.load(scene, data); But it gave an error: foot.babylon

    PositionKind return unusual coordinates

    @Samuel Girardin THANK YOU SO MUCH!!!! Turns out I had to follow this tutorial. I just needed to apply the changes using Object apply. I am new to blender, so I didn't really know this....
  9. function addSphere(scene, { x, y, z }: Object, diameter: number = 0.05, color = new BABYLON.Color3(0, 0, 0)) { const sphere = BABYLON.MeshBuilder.CreateSphere("sphere", { diameter }, scene); const material = new BABYLON.StandardMaterial("texture1", scene); material.diffuseColor = color; sphere.position = new BABYLON.Vector3(x, y, z); sphere.material = material; } const positions = mesh.getVerticesData(BABYLON.VertexBuffer.PositionKind); const zeroCoord = { x: positions[0], y: positions[1], z: positions[2], }; addSphere(scene, zeroCoord, 1); Demo As you can see in the code, I am just trying to get vertices of the foot. and the placing a sphere on the first vertice of the foot. But for some reason, as can be seen in demo, the sphere is added somewhere not even remotely close of the foot. You can download the mesh here. Why is this happening ? I've been trying to fix this for two days now, but I can't seem to do it. Edit: I am using babylonjs exported for blender. Edit2: Added playground url https://www.babylonjs-playground.com/#EEKFSK#2

    Changing part of imported mesh

    Thank you @JCPalmer That is exactly what I ended up doing
  11. I am importing a generated foot mesh. After importing it I strip the jpg that's overlaid. Is it possible to modify color in parts of the foot. Let's say I'd want to make toes red, or half of the foot blue, can i do it after model is imported? Or do I have to overlay another mesh on top and color it ?

    Hot reloading engine

    Oh unfortunately no, it's a work in progress, so I have yet to deploy it anywhere :/ Edit: as @Deltakosh asked, i have deployed it

    Hot reloading engine

    @Deltakosh https://bitbucket.org/ajokub/footfalls-3d/, I've made few changes since i've posted this. I am currently just reloading whole webpage on change. You should comment out footData() from index.js. If you try to comment out one of the nodes inside Scene.js it reloads the canvas, but still has 9 nodes instead of 8

    Hot reloading engine

    // @flow // $FlowIgnore import * as BABYLON from 'babylonjs'; import shortid from 'shortid'; type Color = { r: number, b: number, g: number, }; export default class Scene { _scene: BABYLON.Scene; _camera: BABYLON.ArcRotateCamera; _light: BABYLON.HemisphericLight; constructor(engine: BABYLON.Engine, canvas: HTMLElement) { const scene = new BABYLON.Scene(engine); scene.clearColor = new BABYLON.Color4(0.5, 0.8, 0.6, 0.8); const camera = new BABYLON.ArcRotateCamera('Camera', 1.5 * Math.PI, Math.PI / 8, 50, BABYLON.Vector3.Zero(), scene); camera.setTarget(BABYLON.Vector3.Zero()); camera.attachControl(canvas, false); const light = new BABYLON.HemisphericLight('light1', new BABYLON.Vector3(1, 1, 1), scene); light.intensity = 0.5; const sphereMaterial = new BABYLON.StandardMaterial('texture1', scene); sphereMaterial.alpha = 1; // sphereMaterial.diffuseColor = new BABYLON.Color3(0.5, 0.5, 0.5); sphereMaterial.diffuseColor = new BABYLON.Color3(0, 0, 0.5); const boxCfg = { size: 5, updatable: true, }; const sphere = BABYLON.MeshBuilder.CreateBox('sphere1', boxCfg, scene); sphere.material = sphereMaterial; sphere.position.y = 5; this._scene = scene; this._camera = camera; this._light = light; } render = () => { this._scene.render(); } dispose = () => { this._scene.dispose(); } } import { Engine } from 'babylonjs'; import Scene from './Scene'; export default class RenderEngine { constructor(container) { this._container = container; } animate() { this._engine.runRenderLoop(this._scene.render); window.addEventListener('resize', this._engine.resize); } createScene() { this._scene = new Scene(this._engine, this._canvas); } render = () => { this._canvas = document.createElement('canvas'); this._container.appendChild(this._canvas); this._engine = new Engine(this._canvas, false); this.createScene(); this.animate(); } reRender = () => { this._engine.dispose(); this._container.removeChild(this._canvas); this.render(); } } const root = document.getElementById('root'); const engine = new RenderEngine(root); engine.render(); if (module.hot) { module.hot.accept('./RenderEngine', () => { engine.reRender(); }); } I am currently learning babylon.js and with my set up I have hot reloading, so when any files are changed, engine.reRender() will be called. To test it out I change up color of sphereMaterial. It creates new canvas, but for some reason it still shows the old colors... Is there any way to clear out the scene and engine to load the webgl with new configuration? Thank you.
