Unity2d game development Big Pit of Atlas packaging _ Game development and technology

Unity official website about Sprite Packer explanation as follows:

The Sprite packer is disabled by default but your can configure it from the Editor settings (menu:edit-> Project Setti NGS-> Editor). The sprite packing mode can be changed from Disabled to Enabled for builds (i.e. packing was used for builds but not play M ODE) or Always enabled (i.e. packing is enabled for both play mode and builds).

But in fact Unity 2d mode, Sprite Packer default is not disabled, but always Enabled.

The problem is that if your picture is particularly special, please wait a year for every time you change a map.

The efficiency of this packaged atlas is simply a mortal quiver.

So it is almost certain that it is necessary to manually change it to a enabled for builds.

Remember.
