Remarks

NOTE!!Some of these values are used to index into FCollisionResponseContainers and must be kept in sync. If you add any more TraceQuery="1", you also should change UCollsionProfile::LoadProfileConfig Metadata doesn't work outside of editor, so you'll need to add manually @note : when you add more here for predefined engine channel please change the max in the CollisionProfile search ECC_Destructible in order to use this custom channels we recommend to define in your local file

i.e. #define COLLISION_WEAPON ECC_GameTraceChannel1 and make sure you customize these it in INI file by

in DefaultEngine.ini

[/Script/Engine.CollisionProfile] GameTraceChannel1="Weapon"

also in the INI file, you can override collision profiles that are defined by simply redefining Enum indicating different type of objects for rigid-body collision purposes.
