1. 记录一下版本 unity3D 2017.1.0 obi fluid v4.1
2. 好的一导入obi的package就开始报错(微笑)

这里是warning
Shader warning in 'Obi/Simple Particles': Use of UNITY_MATRIX_MV is detected. To transform a vertex into view space, consider using UnityObjectToViewPos for better performance.
查了一点资料
好家伙...原来是2017.1版本matrix还没有rotation
查询网址：Unity - Scripting API: Matrix4x4.rotation
总结：以上错误都由版本不匹配导致。使用obi fluid插件unity版本必须在2017.2及以上。
3. 重新下载的版本2018.2.4
运行成功
