VRChat added VRCA (?maybe VRCW too) protection

[DeepDishBussy]

how the fuck did this thread turn into whatever this nonsense is? Nobody cares about your morals on ripping/leaking, this thread is to get information on cache encryption, not your dogshit takes.

@StinkerGuy115 why not be original and make your own avatar edits?

[DeepDishBussy]

@c0tt0nc4ndy Can you please take this elsewhere? This thread was not made for arguing about morals

[c0tt0nc4ndy]

@DeepDishBussy No worries! I'll end this discussion here, apologies ^^

[StinkerGuy115]

@c0tt0nc4ndy I really wanted to give you a proper response, but what you said there tells me you are just here to try to make yourself feel good. My original statment called out your hypocrisy in hiding behind "i only go for these models not personal ones" ripping is ripping, youre here, you benefit from ripping, whether its just assets, particle effects, or entire models personal or public.

As @DeepDishBussy said this isnt the place to discuss it, no one in this site has clean hands to debate this.

And FYI I do make my own edits but i guess I didnt need to tell you that since you so boldly made a claim without any evidence

Damn... This is unfortunate news. I hope someone will find some method to be able to rip models again. Probably going to be awhile, though.

[CrystalDust]

XDDDDDDDDDDDDDDDDDD

[esau_winchester]

@crystaldustie can this be used to rip models again ?

[Jumbojaw]

Since VRC is a DX11 game, would it be possible to use gpu buffer rippers like NinjaRipper to extract at least the mesh & textures? Or would anticheat cause problems here?

[CrystalDust]

@Jumbojaw maybe

[CrystalDust]

@crystaldustie vrchat is encryted in aes gcm

[Reym]

@crystaldustie how you do memory dump? there is a part i want to check

[CrystalDust]

@Reym run vrchat without eac

[CrystalDust]

and use process hacker

[StinkerGuy115]

@crystaldustie pretty cool, lotta data to shift through and sort. Put that bad boy in a hex editor and type "avtr" lmao. Or throw it into WinDbg.

Oh yea thought I'd share this, VRChat creates a __data file in C:\Users\username\AppData\LocalLow\Unity\Temp\

It's an avatar data file. VRChat creates it and instantly deletes it. I set permissions to not allow VRChat to delete files in that folder in hopes it might be some sorta briefly made unencrypted data file, I genuinely believe the VRChat devs would be that lazy to do something like this lol. Unfortunately file is still encrypted, though it's essential to loading the avatar.

Disable VRChat's access to the folder and the avatar throws an error bot.

[Reym]

@crystaldustie sounds risky, do i just task kill eac as the game starts?

[CrystalDust]

@Reym u need to just go to vrchat main exe that is in a steam folder and launch that
