Fuck RipperStore! This project was previously owned by rygo6. It has been passed on for me to own and work on. This is the official repository for this project.

This is free. Actually read all of this.

NOTE: Rather pathetically, some are spreading the false rumor this has been bypassed. It has not been bypassed. This is from the malicious scene to try to stop this becoming too common.

This is a rather invasive anti-avatar-ripping system to be used for VRChat. It will protect against your avatar being ripped, extracted and edited. It will also protect against your avatar being ripped and re-uploaded without edits.

This system will randomize all the vertices of your avatar's mesh, then write that to disk. Then rely on a custom shader with a 32 bit key to un-randomize the vertex positions in game. This is not done through blend shapes. Rather this will copy, and destructively edit, the 'Basis' layer of your mesh. It will also obfuscate pretty much everything else on your avatar to confusing as a extra middle finger for the ripper.

7. Hall Of Shame

1. For a user to see your avatar properly in VRChat, they must have your avatar fully shown. Shaders, animations and all. You are invisible otherwise.

2. This synchronizes the key with Avatar 3.0 parameters and does take up 32 bits. So this system can only work with avatars that use the VRChat Avatar 3.0 SDK.

3. Only a shader from Supported Shaders will work with this. To request another shader to be supported, feel free to ask in the discussions tab here, or in the discord, seen in the Support section.

1. Ensure you are using latest VRC SDK.
2. Download the supported shader of your choice from Supported Shaders, and import it into your Unity project.
3. Click (Download). Once downloaded, extract it. Once you have the folder, put that into your assets folder of your unity project.

Be sure all of this is set correctly on your FBX's. (Legacy blend shape normals and read/write on too!)

1. Add the KannaProteccRoot component onto the root GameObject of your avatar, next to the VRCAvatarDescriptor component.

2. Ensure your VRCAvatarDescriptor has an AnimatorController specified in the 'FX Playable Layer' slot. The AnimatorController you specify should not be shared between multiple avatars, Kanna Protecc is going to write states into the controller which will need to be different for different avatars.
3. Ensure there is also an Animator component on this root GameObject, and that its 'Controller' slot points to the same AnimatorController in the 'FX Playable Layer' slot on the VRCAvatarDescriptor.

5. In the 'Parameters' slot of your VRCAvatarDescriptor ensure you have an 'Expression Parameters' object.

VRC API stores old uploads of your avatar! So if you start uploading an encrypted avatar with an ID that you previously uploaded non-encrypted, it may entirely negate any benefit this provides as rippers can just download an older version that was not encrypted.

1. Go into the VRChat SDK Inspector in the Unity Editor, then under 'Content Manager' find the avatar you wish to protect and delete it entirely from the VRC backend.
2. Go to your current avatar's Pipeline Manager component and click the Detach (Optional) button so it will generate a new avatar id on upload.

1. Ensure any meshes you wish to have encrypted are using a compatible shader, such as Poiyomi.
2. On the KannaProteccRoot component click the 'Encrypt Avatar' button. This will lock all of your materials, make all necessary edits to your AnimatorController, and make a duplicate of your avatar which is encrypted. Be aware your duplicated avatar with "_Encrypted" appended to it's name will appear completely garbled in the editor. The garbled materials will be invisible to those who have you not fully shown.
3. Go to the VRChat SDK Menu then 'Build and Publish' your avatar which has '_Encrypted' appended to the name.

I found some Poi 8/8.1 materials get into a weird state with Lock/Unlock and Kanna Protecc can't lock them. If you get errors that say something like 'Trying to Inject not-locked shader?!' go to the Poi 8/8.1 material it is complaining about and manually click the Lock/Unlock button to get it out of its weird state.

1. After upload completes, go to the GameObject of your encrypted avatar. Find the Pipeline Manager component and copy it's blueprint ID. Then paste the blueprint ID into the Pipeline Manager on the un-encrypted avatar and click 'Attach'. This is important.
2. Now on the KannaProteccRoot component click the 'Write Keys' button. Ensure VRC is closed when you do this, as VRC might disallow writing to the file. This will actually read in and alter the saved 3.0 parameters from your VRChat folder to include the new key so you don't have to enter them in-game. This also means if you "Reset Avatar" in game through the 3.0 menu, it will reset your keys and you will need to re-export them with the 'Write Keys' button!
3. This should provide ample error dialogues or console errors, so ensure no errors came up!. It should popup a success dialogue if it did it correctly. If there were issues make sure the 'Vrc Saved Params Path' actually points to your LocalAvatarData folder.
4. You only need to run 'Write Keys' once on first setup, or when you change keys.

*Ensure VRChat is closed when you write keys otherwise VRChat may just overwrite them immediately with zeroes!

If you wish to see your avatar again as normal and not encrypted, click on your original non-encrypted avatar and click unlock materials.

I will keep transparent here without guiding rippers on how to attack your works. This is not foolproof, but the best you can get at this time. Rip wise, this cannot be currently ripped without a insane amount of work, as ripping compiled shadercode, reversing it back to unity compatible code and also getting hold of the keys would be hell. Hotswap wise, a dedicated enough ripper with experience with mods could hotswap your avatar. This is not immune to that. (Soon to be countered with traps making even that extremely harder to do) You can however put a watermark on your avatar to drive hotswappers into being banned which they wont be able to remove, as the meshes will be encrypted, regardless of hotswap. A hotswap done with the high amount of work i have mentioned here would only get the avatar working normally in game; not in unity.

A typical hotswap will not bypass this. It would take a specialized one.

If you have any more questions, or suggestions, feel free to join the Kanna Protecc discord: https://discord.gg/SyZcuTPXZA

This will let you keep up to date with major features that will take time to implement. This does not act as a changelog, nor will it have every upcoming feature listed. Only time-consuming ones. https://trello.com/b/k88bNBvd/kanna-protecc

People who lied claiming they could bypass this yet would never put their money where their mouth is, or just terrible people in general, such as contributors to the ripping scene.

Idiot dev of sars who claims he doesn't endorse ripping, meanwhile majority admins rip and AC outright told someone they can rip any avatar. Even in cool people role has people openly expressing they make and use crashers. Proof of admin endorsing it:
