Set Custom Model Data Strings

Use Set Custom Model Data Strings with the ordered inputs below.

Where to find it

Set Variable → Operations → Choose Operation → Item. Requires Dev access to configure, then a successful compile to activate.

Inputs

Input	Type	Role	Requirement	Default / constraint
Result	Item	Variable binding	Required	Required
Item to Change (omit for destination)	Item	Value	Optional	Omitted; see behavior below
Strings	String	Value	Required; ordered plural group	Required

Result and behavior

Stores the result in the first configured destination Variable. Its type must match the result and any generic element/key types.

Configuration example

Block: Set Variable → Operations
Operation: Set Custom Model Data Strings
Result: Private Item result
Item to Change (omit for destination): (omit for this example)
Strings: Hello

Use this as an editor configuration: declare any Variables/collections first and choose real locations/eligible targets for your plot. It is not pasteable source code.

Restrictions and troubleshooting

Item transformations copy their source metadata. For optional Item to Change, omission uses the current destination Item, which must already be assigned. An Item output does not automatically replace a player’s held stack; use a suitable inventory action afterward.
