.crt files

[Albalrogue]

Hello,

I'm wanting to replace the Grox in my spore game with a remade version (along with new vehicles and buildings). The thing is that in the "editorsaves" package where the creature is, there are these ".creaturedata" files but no ".crt" files. Am I to assume that they are in fact the same and only need the change the .creaturedata to .crt or is there more to it?
