how files are created.cob

[Capturador]

Hi, I'm looking for help to see how the [.cob] files are created, since I want to change the textures of various creatures to add more variety
I put example of the helmetcrab I would like to be able to add three types of different colors

If you could guide how to create them, I would appreciate it

I'd suggest you to use copied and hexed versions to create more variety.
At the moment we don't have the possibility to create .cob-files completely on our own....
Except @ can tell you something else
