Eden mission editor has brand new categories for entities like characters or “props” as bis now calls empty objects. Below is how PMC Opteryx Objects were initially setup.

This also includes Map Builder library class examples.

// eden -> props -> PMC Opteryx Objects
class CfgEditorCategories
{
	class pmc_opx_objects
	{
		displayName = "PMC Opteryx Objects";

// eden -> props -> PMC Opteryx Objects -> below ...
class CfgEditorSubcategories
{
	class pmc_opx_airport
	{
		displayName = "Airport";

// old 2d editor and map builder
// but is the old 2d stuff even used anymore?
class CfgVehicleClasses
{
	class pmc_opx_objects_buildings
	{
		displayName = "PMC OPX Objects - Buildings";
		mapbuilder_library = "PMC Opteryx Objects";
		mapbuilder_displayname = "Buildings";
	};
 
	class pmc_opx_objects_misc: pmc_opx_objects_buildings
	{
		displayName = "PMC OPX Objects - Misc";
		mapbuilder_displayname = "Misc";

CfgVehicles:

class cfgVehicles
{
        // stuff
	class land_pmc_opx_atc1: House
	{
                // stuff
		vehicleClass = "pmc_opx_objects_buildings";
		editorCategory = "pmc_opx_objects";
		editorSubcategory = "pmc_opx_airport";
