The tool is currently in the testing phase and is not yet fully developed.
First you need to have pyhton installed, and then you need to run that command
pip install zstandard
Then you need the hash_strings.txt file from Light Converter from KillzXGaming (That tool crashes the game) , place it in the same folder as the .py and the .data,
Then run this command to extract a file
python cam_tool.py extract "D:\YOUR_PATH\render_params.data"
and then to pack it use
python cam_tool.py pack "D:\YOUR_PATH\render_params.data.json"
the render_params.data must be in the same folder as the json.
I heard that the community needs a tool to extract the render_params.data file. I’m not very experienced with this, so I used AI to help me.
