Would it be an alright workaround to still use the CCEX plugin but just not let the player access the character creator scene?
If so here's my solution;
>Install CCEX as normal with all of the images
>Change the plugin parameters "Print to Console" to be true
>Playtest the game and make your custom character with everything but the dynamic pieces.
>Save your custom character and open the console log (F8). Copy the text that's there (Yes, all of it.)
>Paste that into an event that runs at the very start of your game using a script call command. Edit the part that says var id = 0 to have the Actor ID that you want to use. e.g. var id = 1
>With that set up, you can remove the plugin command to open the character creator scene. You'll probably also want to go through your image files and remove all of the extra hairs/eyes e.t.c that you're not using so it doesn't bulk up the game file size.
And then you'll be able to use the Dynamic Actors plugin as instructed whilst bypassing the actual character creator.
