Here I will go over how to dump models and textures from latest builds of The Finals. First download files and put them into a folder, lets only focus on .ucas.

Use VGM Toolbox to cut out some data. I used 2F47616D652F as my string. This refers to /Game/ in the files.

You will end up with alot of 1KB files I would use this powershell file to delete them before trying to rename directory.
NOTE:
You may want too change 400 file size to 10000 I found that to work better.

Once you cut out all files use VGM Toolbox again to rename these files to give a proper file structure.

When its complete you will see a directory with files inside named to proper names.

Textures can be done with Raw Tex. Use VGM Toolbox to cut out files to be able to convert them. I have provided a  .bat file below to get started.

There are a few types here so be sure to convert them all properly:

Models were a bit more tricky but I was able to pull something from the data using Model Researcher.

This is the only way I found to pull meshes and textures from game since encryption.
