在安装c4d 的octane渲染器时，在C:WindowsSystem32driversetc这个文件夹里找不到hosts文件，解决
方法一：先检查该文件是否被隐藏，具体步骤是：打开工具——文件夹选项——取消隐藏文件夹，如下图
方法二：
首先在系统桌面空白处右击鼠标选择新建、选择文本文档。
2、如果第一步操作正确那么就可以创建出一个如下图一样的文本文档。
3、将一下内容复制到创建好的文本文档中：
# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
#127.0.0.1 gilisoft.com
完成以上粗体字的内容复制后在关闭txt文本的时候选择保存内容。
4、回到系统桌面右击txt文本然后选择重命名，将新建文本文档txt修改为hosts！注意不要有任何多余的空格或者是符号。
5、将已经修改好的文档直接从桌面拖到C:WindowsSystem32driversetc目录中即可解决hosts文件没有了的问题。
