I've been trying to use the Custom Datafile functionality to create a new Species/Metavariant (or Metatype whichever will work) for a player of mine to use for a character. The end result I wish to have a species with different min/max attributes than exists currently in the other metatypes/metavariants along with a set of both positive and negative qualities. I've compiled the rough total BP cost from using the Runner's Companion (2nd printing) now I'm trying to get Chummer to have the same information for my player to use your program for character creation.
I started from a copy of the current Metatype datafile and renaming it as directed to custom_metatypes.
Next, I deleted redundant information and began editing an existing Metavariant to have the qualities of the new Metavariant I wished to create. Then I saved the file and opened Chummer. Alas, the new Metavariant did not appear on the pull-down list.
Next, I tried creating my desired species as a new Metatype again starting from a copy of the original datafile and renaming it, editing it as necessary to have the necessary statistics and qualities. Saved, opened Chummer; alas, no new Metatype.
Am I doing something incorrect?
