How to achieve a packaging method like PUBG?

Development Programming & Scripting
1

I would like to ask, how to achieve the packaging method like PUBG? Because I see that each chunkID is divided into multiple category names, which is very detailed. I have studied the Chunk packaging method, but each ID has only one pak, how can this be achieved? I have no clue.
Thanks for your time.

Haven’t done this myself but maybe this can point you in the right direction.

That’s chunking. It involves some setup of your assets in an ini file, or in the editor using primory asset tags. You can get a lot of useful information here:

Hope this helps.

Thank you for your answer, I did it with Chunk, but it can only generate one pak per ID,
For example: Chunk0.pak, Chunk1.pak, Chunk2.pak.

But PUBG is similar to this, for example: Chunk0_A.pak, Chunk0_B.pak.
Different names can be distinguished after each same ID, so I am curious how it is generated.

I was researching this thing and found no answers. As a guess, I thought perhaps simply renaming the pak files to whatever I wanted might work… and sure enough, it did.

Here is what my files were initial called after building:

pakchunk0-WindowsNoEditor.pak
pakchunk1-WindowsNoEditor.pak

I manually renamed “pakchunk1-WindowsNoEditor.pak” to “pakchunk1001-PlayerPowerupAuxAmmo-WindowsNoEditor.pak” and tried running the game.

Game ran fine, and I verified it automatically loaded the pak file(s) via the logs:

LogD3D12RHI: Aftermath initialized

So, I think it may be possible to do this by simply renaming the files post-build. I have post-build scripts already in place for my project, so I’ll just add the renaming process to that.

Hope this helps!!
