Pak working flow

Requires

• UE4 4.16.2: Code is simple and this version is not prerequisite.
• Python 3.x: The scripts in ProjectUtils are written with python 3.x.

Steps

• Use the ExportAssetDependenciesPlugin to export dependecies infomation of what you want to collect into pak files.
• Cook all content.
• Setup the config in ProjectUtils.
• Use generate bat tool in ProjectUtils to produce pak files. Pay attention to the command line, especially the response files' content.
• Exclude the assets you have exported above and package your project.
• Run game and input the root dir's TestPaks path and open MyTestLevel to see the result.

Adition

1.Add a plugin to export asset dependencies.

Bug

• I do not know why UE4.15.3 just produces uasset file. This will cause unexpected banding effects if you use static ligting.
