Changing the Color of an Object3D Mesh in Three.js

Question

Changing the Color of an Object3D Mesh in Three.js

Seeking advice on how to update the color of a Three.js Object3D. Initially created using MeshStandardMaterial, this object is later retrieved from the scene by its ID. Is it possible to change the color of the Mesh at this stage?

If needing to replace the 3D object entirely, is there a method to retrieve the original geometry used in its construction directly from the Object3D? Avoiding a mapping of geometry to ID due to code clutter, one potential solution is storing the geometry in Object3D.UserData. However, this approach is less efficient as meshes are initially constructed elsewhere and then added to the scene (UserData is only accessible after adding to the scene).

I discovered a method to incorporate texture into an Object3D.

To adjust the material of meshes, you can utilize the children property.

    function onLoad(object) {
      // The `children` array consists of one or more Mesh objects
      object.children.forEach((mesh) => {
        if (!mesh) return;
        const material = mesh.material;

        material.map = ghostColorTexture;
        material.normalMap = ghostNormalTexture;
      });
    }

    const objLoader = new OBJLoader();

    objLoader.load(
      '/models/ghost/model/ghost.obj',
      onLoad,
      undefined,
      function (error) {
        console.error('error', error);
      }
    );

An Element can be a Shape that consists of a Pattern and a Texture. If you wish to change the pattern, simply select that texture, and apply a new design to it:

element.texture.pattern.setHex(0xff9900); // Changes to orange

In the documentation, you will find that .pattern is a part of TextureColor and .material is related to Texture
