First your gonna need to realise that this point in time, we can only mod DLC Outfits (Bit of a bummer that is hopefully not the case soon)
Now that we have that out of the way. Lets start!
Step 1:
First your gonna need to extract the .pak files.
To do this, your gonna need.
QuickBMS (4GB Exe)
RE2's QuickBMS Script
The File list for the QuickBMS Script (This is updated regularly)
Put All of these files into the same folder.
Step 2:
Drag the QuickBMS script into the 4gb exe and it should ask you to locate the .pak you want to extract. The base games .pak is located next to the games .EXE and the DLC's .paks are located in seperate folders. Check this File list To figure out which one you want to extract
Then it will ask you to select an output folder. Always create a brand new folder for everything to extract into, as while some files are organised and named. A lot arent and just all dropped into the same place.
Step 3:
As i stated earlier, you can only mod DLC outfits. So by this point you should have the base games .PAK Extracted, and a few DLC ones extracted to swap over.
The next thing to do is to take the "Natives" Folder that you got from extracting your selected DLC Outfit, And drop it right next to the games .EXE
Then, Inside of that "Natives" folder you should see a few more folders called "ObjectRoot, SectionRoot and Streaming."
Make your way to this location "objectroot\prefab\character\survivor\parts\*Character ID*" Here there will be 3 .pfb Files. One for hair, Head and Body. This is what your gonna need to swap models around.
Now, within the Base games .Pak if you make your way to that same folder location. Your gonna find all the same pfb files you need. Except every single Character in the game will be here.
Take the 3 that you need from the base games .pak and rename them to match the DLC's, Then just drag and drop them into the DLC Folder to replace them. (Always make backups)
Step 4:
Right! your almost there! Now we just need to invalidate the DLC's .pak file to stop the game from loading it, An easy way to do this is to just remove the .pak file from the games Archives, BUT if you plan on sharing this mod, Its probably best to just Open the .pak in Notepad++ then CRTL + A all of the contents within, And just Remove it all then save.
Then go test y0 mod! (Simple Right?)
Any question? Ask below! Enjoy!

模型，以后渣5不知道能改吗

你倒是翻译一下啊

首先，你需要意识到这一点，我们只能修改DLC装备（有点麻烦，希望不会很快发生这种情况）。
现在我们已经把它挡在一边了。我们开始吧！
步骤1：
首先你需要提取.pak文件。
要做到这一点，你需要：
QuickBMS（4GB exe）
RE2的QuickBMS脚本
QuickBMS脚本的文件列表（定期更新）
将所有这些文件放入同一文件夹。
步骤2：
将quickbms脚本拖到4GB exe中，它会要求您找到要提取的.pak。base games.pak位于games.exe旁边，dlc的.pak位于单独的文件夹中。检查此文件列表以确定要提取哪个文件
然后它会要求您选择一个输出文件夹。总是创建一个全新的文件夹，以便将所有内容提取到其中，就像组织和命名某些文件一样。很多不是，只是都落在了同一个地方。
步骤3：
如我之前所述，您只能改装DLC装备。所以到目前为止，您应该已经提取了基本游戏.pak，并且提取了一些DLC游戏来交换。
接下来要做的是从解压选定的DLC装备中获得“natives”文件夹，并将其放在games.exe旁边。
然后，在这个“natives”文件夹中，您应该看到更多的文件夹，称为“objectRoot、sectionRoot和streaming”。
在这里有3个.pfb文件。一个用于头发，头部和身体。这就是你需要交换模型的地方。
现在，在base games.pak中，如果你找到了相同的文件夹位置。你会找到所有你需要的PFB文件。除了游戏中的每个角色都会在这里。
从base games.pak中获取您需要的3，并对其进行重命名以匹配dlc，然后将它们拖放到dlc文件夹中以替换它们。（始终备份）
步骤4：
ok！你快完成了！现在我们只需要使dlc的.pak文件无效，就可以阻止加载游戏，一个简单的方法就是从游戏档案中删除.pak文件，但是如果你打算共享这个mod，最好是在记事本+中打开.pak，然后打开crtl+a中的所有内容，然后删除所有内容，然后保存。
然后去测试Y0模块！（很简单对吗？）
有问题吗？请在下面提问！享受吧！

想在生8把罗斯模型拿出来替换重制4的艾什莉，是不是要删除罗斯原始骨架套在艾什莉骨架上？不是很懂
