Paint Details
根本原因还没搞清楚，测试下来，删除Paint Details可以不闪退。但这样场景里的草就没了，后面还要深入查。

2022/03/25 补充：
搜到了相关的报错，但它竟然是【Won't Fix 】状态，只能在各种参数设置方面下手了。一通乱改，最终发现要把Mesh的Read/Write Enabled开启。同时Texture的RW也要开启，不然会报错。
在2018.1的文档里还能看到一点提示，后续版本啥也没有了：
Note that if you want to assign a Texture to a Terrain, you need to open the Texture Importer and tick the Read/Write Enabled checkbox.

开启Detail Mesh的Read/Write Enabled
问题原因还是没搞清，但应该没法进一步处理了。Unity其他地方也有必须开启RW的情景，如Particle System用到的Mesh。
