Got it.

Does that mean you extract the unencrypted part and just mirror everything, or...?

[Bigchillghost]

Just an attempt to restore the X factor based on the overlapped top projection and use the UV to determine the sign. Also need to remap the factor to its original boundary since it uses a different scale.

Did you tring with Fast and Furious samples?

[Javiliyors]

it is possible to extract decript tracks from PC2 and AMS2 ???, they have the same engine

Unfortunately none of these samples I checked come with a valid top projection. Same circumstance might be applied to most of the meb files from PC3. So it seems pretty obvious that it's not meant to be handled in this way.

Some years ago i send a model ripped using Ninja Ripper to Dave Noonan (author of 3DSimEd), he managed to restore mesh, using information from shader, but that method works only with one car model, others require another keys, which Noonan fails to locate and abandoned this game.
Sample rip here.
Vertices decoding are in Shader_0000.gs, fragment (~1/7 of code):

Hi,

Can anyone help figure it out.
These are the car files Acura NSX racing 1997 and Chevrolet Corvette C8r from "PS4" - PC3.
https://sharemods.com/tl3vvn3atq0u/Test.zip.html

But they do not open in SMS import. Try to open. Previously, models were usually opened. What could be the reason?
