TUTORIAL [Exporting A VRCA to Unity]

Literal

Hello Everyone!!

i do have an easier way of explaining the process and explanations on how to extract VRCA's

Aquire your Ripper/Extractor

Below is a list of free rippers with my personal opinion on the ripper

SARS
https://github.com/Dean2k/SARS
Sars has pretty much everything needed minus some caveats that I found

Material animation changing isnt a thing i dont think.
I dont believe this is still actively worked on

ASSETRIPPER
https://github.com/AssetRipper/AssetRipper
The basic tool for extraction CAB files from a VRCA (all a vrca's are, is a bundled CAB file)

Doesn't give fixed prefab with scripts (Unless you use FACS)
Material exporting has different color than original model
Still being updated

WPFMA SDK

Ripper Store Post: https://forum.ripper.store/topic/138774/who-pays-for-models-anyways-open-requests-modded-sdk
Yes im putting this in here as its something I created

Still being updated
Built in VRCA Exporter (Not External) (Find in settings tab)
atm pulling avatar .anim from files is being stubborn!

Find your VRCA or Decrypt it on your own!

From my knowledge and exploring the Ripper.store space!

You can find servers that store VRCA files
Find a service (I know some servers have automated bots that pull the file for you)
Some Ripper store users offer services that you can request on!
For Decrypting on your own you need a client sadly!

Have Unity Hub, VCC or ALCOM

Version 2022.3.22f1 or 2022.3.6f1 if your using WPFMA SDK
Version 2022.3.22f1, 2022.3.6f1, or 2019.4.31f1 works for SARS an AssetRipper!

Now comes the extractor portion

Open your choice of extractor I'll be giving a basic guide into each extractor

SARS

Make sure you have the VRCA file! before opening this

This is SARS to extract a file please follow the steps

Click VRCA Information after spamming cancel a few times

Click load VRCA/VRCW and find the file needed

Set your settings if you want! and click extract VRCA/VRCW to start Extracting

Once you have extracted drag your new folder into your unity scene! and you will have the model in the form that sars gives it to you!

ASSET RIPPER

Download the asset ripper and run the .exe that is stored in it, should pop up a console that opens a browser tab

To start extracting with this! Click File and open file then select the VRCA, after selecting it please click View Loaded Filed

After clicking view loaded files It should look something like this

Click Export and follow the rest from there! drag it into your unity an you should have the prefab

WPFMA SDK

Yes this is my personal free ripper so i do know alot more on how this functions!

Set up the SDK in unity (I would recommend a Unity hub project) same principle as opening a unity package to import a model into your unity!

Once You have installed the package please click Open WPFMA SDK it should open a panel that looks like this!

Click Settings then exporter and turn on exporter

Inside the Exporter tab drag or select the VRCA that you want and drag it in!

Click Preview this should put a preview of the model within your scene

After the model is previewed you can do either 2 things! Extract without any shaders an it defaults to a standard shader, or Drop down on the VRCA and this SDK shows what shaders are required for a 1 to 1 rip with material changes

Or Extract!

Now that you have the files!

These have been life saving to be honest

Pumpkin Avatar Tools
FACs Utils

Some questions that people have that i can answer

Why isnt the shader material changing in gesture manger?

Answer: its because that shader you applied isnt the exact shader the animation file is calling!

Why isn't the menu or parameters there when I rip the model?

Answer: It depends on what Ripper you use! AssetRipper doesnt resolve those conflicts when exporting like ARC( Aka SARS) or WPFMA SDK does! (Both use logic from facs utils automatically in the rip)

Will i get banned for ripping?

Answer: Technically speaking, reverse engineering an reuploading someone else's model is against TOS! so there is a risk, how ever i rarely ever hear people getting banned over ripping models!

HAPPY RIPPING OR WHAT EVER YOU DO!

Poster Note: Honestly made this for everyone who is struggling to rip, and to give people an exact way! now with asset ripper, its a gamble because i havn't used them in a while
