在发送到mesh filter unity c之前，我可以将网格添加到一起吗

这个问题是统一c中的一般问题 我知道我不能有多个网格过滤器 但是我在一个脚本中生成了不止一个网格，我想在一个对象中一次性渲染所有网格，但我不想合并顶点数组，这样我仍然可以动态删除面

基本思想是将体素作为一个游戏对象，但通过脚本由不同的面组成 我想在不进入巨大阵列的情况下保持面部的可访问性

所以现在我有6个面作为网格，我不知道如何渲染它们

---

做这件事最好的方法是什么，最好的方法是什么，这里没有答案，所以我有一些答案，但仍然需要关于概念方法的指导 所以我重写了我的体素，但现在我在考虑写一系列函数来破坏那些不需要的脸，但问题是，如果我把我的三角形放在0上，我认为这是最容易的，这不像释放任何内存，它只是不可见，所以这不是一个好办法

有人会怎么做一些优化的体素呢

我想从我的代码中你会明白我是一个初学者
