I tried recreating it from scratch, creating a new primalgameBp, test level and game mode based on generic mod.
then I created a saber_bp child, and copied of the mesh and colorize MIC, dino entry and dinoicon files. I re-cooked and tested in single player-- the game output folder had SOME files in it this time at least, but I can’t summon the create BP ingame at all =(
