多种材料的状态如何? [英] What is the status on Multiple Materials?

问题描述

我找不到关于多种材料的任何文档 - 我知道 MultiMaterial 已被弃用，但它现在如何工作?

I cannot find any documentation on multiple materials - i know MultiMaterial has been deprecated but how does it work now?

three.js 是否支持这个，如果支持，faceVertexUvs 如何映射到多种材质(我的意思是请举个例子)

Does three.js support this and if so how does faceVertexUvs map to multiple material (i mean a practicle example please)

推荐答案

要将多种材质应用到一个对象，您现在可以将它们作为数组分配给材质属性.

To apply multiple materials to an object, you are now able to assign them just as an array to the material property.

mesh.material = [material1, material2, material3];

请参阅迁移指南 (r84 → r85):

MultiMaterial 已被删除.改用数组.

MultiMaterial has been removed. Use an Array instead.

faceVertexUvs是一个多维数组，第一个索引代表材质索引.

The faceVertexUvs is a multidimensional array, where the first index represents the material index.

geometry.faceVertexUvs[ materialIndex ][ faceIndex ][ vertexIndex ]

(参考:three.js -geometry.faceVertexUvs[0][0][index] 与 geometry.vertices[index])

在这两种情况下，Three.js Docs 确实可以做得更好.

The Three.js Docs could be indeed a bit better in both cases.
