A Plotagon Character Data file (.pcd) works by a header and data blocks. There is a chunk data length and element data length for each block that make up the character in total.

Here, you can modify the raw image of the pcd and change your skin color to a custom one, because now you don't need to have a custom skin color option on the character editor being an obfuscated pcf anymore.

All your characters should be located at C:\ProgramData\PLOTAGON_PROGRAMDATA_GUID\Bundles.

Note: if you want to use this universally, you have to copy it to C:/Windows/System32.

How to use

Well, you basically extract the PCD file first with plotcharactertexmod pcdfile png

Then you use a sorta photo editor to modify it to eg. create custom skin color

Then you come back after moving the saved modified texture to the location the PCD originally was, and do plotcharactertexmod modify:pcdfile newpcdfile

Then you feel free to delete the original and rename the new pcd to the old one's name

Then it works

You should get something like your custom skin or whatever and use it.
