Mesh cannot be displayed normally after Unity3D particle effects are packaged into AB package
After the particle effects are typed into an Asset Bundle, load and play, the particle effects that use the mesh cannot be displayed. The
official website explains this as:
Meshes must be read/write enabled to work on the Particle System.
If you assign them in the Editor, Unity handles this for you.
But if you want to assign different meshes at run time, you need to check the Read/Write Enabled setting in the Import Settings.
General idea: When you need to reassign Mesh, you need to open the Read/Write setting, but UnityEditor will automatically perform this operation.
Note:
1. If it is an AB package, UnityEditor will not perform this operation. It is necessary to set up FBX before packaging.
2. The same situation will occur when the application package is packaged.
