Getting a Backpack to float.

[maverickzer0 18]

I've been trying to get a backpack in the 3DEN editor to float in the air like you can most other objects. As I understand it, backpacks are exempt from this as they are not handled like other physics objects and therefore just spawn on the ground. 
All I need it for is a screenshot, I don't need the backpack to be interactable nor do I need it to move, just to stay in place and not drop to the floor. I've attempted to use the attachTo command and the attatchToRelative as well as converting a simple object like a cone into a backpack - which worked - but still ended up with the backpack spawning on the ground.

 

Any help would be appreciated.

Backpacks work differently. You need to move the objectParent rather than the backpack.

Just spawn it as a simple object using the backpack's model...

TAG_fnc_displayBackpack = {
	params[ [ "_backpackType", objNull, [ objNull, "", configFile ] ] ];
	
	if ( _backpackType isEqualType objNull && { isNull _backpackType } ) exitWith{ objNull };
	
	if ( _backpackType isEqualType objNull ) then {
		_backpackType = typeOf _backpackType;
	};
	
	if ( _backpackType isEqualType "" ) then {
		_backpackType = configFile >> "CfgVehicles" >> _backpackType;
	};
	
	if !( isClass( _backpackType ) ) exitWith{ objNull };
	
	private _model = getText( _backpackType >> "model" );
	
	if ( _model select[ 0, 1 ] == "\" ) then {
		_model = _model select[ 1, count _model ];
	};
	
	private _eyeHeight = ASLToAGL( eyePos player ) select 2;
	private _pos = AGLToASL( player getPos[ 4, getDir player ] vectorAdd[ 0, 0, _eyeHeight ] );
	private _object = createSimpleObject[ _model, _pos, true ];
	_object setDir ( _object getDir player );
	
	_object
};

backpack player call TAG_fnc_displayBackpack;

 

 

Or line up a nice shot of the players backpack in the editor, using the arsenal sphere as a backdrop.

	_camera setDir 180;

Or there is also Eden Editor: Configuring Asset Previews that could be useful.

Thanks for both the replies, but i found this thread on Reddit which emulated what I wanted pretty much perfectly. Though, on a separate but kind of the same topic, anyone have a list of particle effect class names? I've figured out how to spawn particle effects in but I can't find a list of them anywhere.

That is functionally the equivalent of @Larrow's first solution above - creating a simple object.

See CfgCloudlets in the config viewer. Some particle effects rely on engine parameters so may not spawn properly/look correct.
