Data Modifiers

Data modifiers perform logical, numeric, and string-based operations within the graph. They are used to compare values, perform calculations, filter data, and drive conditional behavior.

These modifiers do not affect geometry directly but are essential for building dynamic, rule-based configurator logic.

Modifier	Description	Input
Basic logic	Uses a logic comparison between two values and outputs a boolean result indicating whether the condition is true or false.	Inputs Operation: Choose between `==`, `>`, `<`, `<=`, `>=`. A: First value. B: Second value. Outputs Result: Boolean result of the comparison.
Basic Logic (booleans)	A logic gate operating on two boolean values that outputs a boolean result.	Inputs Operation: Choose between `And`, `Or`, or `Xor`. A: Boolean value. B: Boolean value. Outputs Result: Boolean result.
Basic math	Applies a basic mathematical operation between two numeric values.	Inputs Operation: Choose between `Add`, `Subtract`, `Multiply`, or `Divide`. A: First numeric value. B: Second numeric value. Outputs Number: Result of the calculation.
Filter tag	Filters geometry based on assigned tags.	Inputs Geometry: Geometry to be filtered. All Tags Of: Geometry with all of these tags is kept. No Tags Of: Geometry with any of these tags is removed. Outputs Geometry: Filtered geometry.
Font Characters	Outputs the available characters of a given font.	Inputs Font: The font to query. Make Regex: Outputs the characters as a regular expression when enabled. Outputs Characters: Available font characters.
Number to String	Converts a numeric value into a text representation.	Inputs Number: Numeric value to convert. Precision: Number of decimal places. Outputs Text: Converted text value.
Numeric variable	Stores a reusable numeric value that can be referenced throughout the graph.	Inputs Viewer Value: Value used during visualization. Export Value: Optional value used during export. Outputs Number: The numeric value.
Platform	Allows you to assign different resources for desktop, mobile, and export contexts. The front-end automatically detects the user’s device and loads the appropriate resources, enabling optimized assets for mobile without sacrificing desktop quality. Export inputs can be used for production-specific outputs. This works across all resource types, including geometry, color maps, and materials.	Inputs Interpretation Type Defines how the input resources should be interpreted (e.g. Geometry, Color Map, Materials). Desktop Resource input used for desktop environments. Typically linked to higher-quality or more detailed assets. Mobile Resource input used for mobile devices. Allows optimized (lighter) assets to be provided for better performance. Export Resource input used for export contexts (e.g. production files, downloads). Can differ from visual assets to match manufacturing or output requirements. Outputs Output The selected resource based on the active platform context (desktop, mobile, or export), as resolved by the front-end.
Resource fetcher	Fetches a resource from a specified URL.	Inputs URL: URL of the resource to fetch. Fallback URL: URL used if the primary fetch fails. Interpretation Type: Expected resource type. Ignore Errors: Determines whether errors are ignored. Outputs Output: The fetched resource. Fetch OK: Indicates whether the fetch succeeded.
Round Number	Rounds a numeric value according to the selected mode.	Inputs Number: Value to round. Mode: Rounding mode (e.g. Nearest). Outputs Result: Rounded number.
String Length	Returns the length of a text string.	Inputs Text: Input string. Outputs Length: Number of characters.
String Query	Checks whether a string matches a condition and outputs a boolean result.	Inputs Text: Target string. Other: Comparison string. Query: Choose between: Equals Not Equals Contains Not Contains Starts With Ends With Case Sensitive: Defines whether uppercase and lowercase letters are treated as distinct. Outputs Result: Boolean result.
String Replace	Replaces parts of a string with another value.	Inputs Text: Input string. Case Sensitive: Case sensitivity toggle. Input: Substring or pattern to replace. Replacement: Replacement text. Outputs Result: Modified string.
String Substring	Extracts a substring using a regular expression.	Inputs Text: Input string. Regex: Regular expression pattern. Outputs Result: Extracted substring.
String Template	Builds a text string from a template using placeholders. Placeholders are defined using square brackets (`[1]`, `[2]`, …) and replaced by connected inputs. Note: Save and refresh after setting the template to expose the input sockets.	Inputs Template: String template. Outputs Text: Generated string.
Tag	Adds or removes a tag on a geometry.	Inputs Target: Target geometry. Tag: Tag value. Mode: Add or remove. Outputs Geometry: Tagged geometry.
Text variable	Stores a reusable text value that can be referenced throughout the graph.	Inputs Viewer Value: Value used during visualization. Export Value: Optional value used during export. Outputs Text: The text value.
