#include <ComposableCameraTypeAsset.h>

Describes a camera-level variable (internal or caller-exposed).

This is the struct used for BOTH InternalVariables and ExposedVariables on UComposableCameraTypeAsset — the two arrays share the same field layout and the runtime also stores both in a single FName→offset map. The distinction lives purely at the authoring surface: which array an entry lives in.

• InternalVariables: node-only slots. InitialValueString is applied at camera instantiation; callers have no way to override it.

• ExposedVariables: same node-level read/write semantics, but the caller's FComposableCameraParameterBlock may override the initial value at activation time (by keying on VariableName, same channel used for ExposedParameters). After activation, there is no external read/write API for them — they behave exactly like internal variables from that point on.

All fields apply to both usages; none are ignored in either case.

Public Attributes¶

VariableGuid¶

FGuid VariableGuid

Stable identifier for this variable, independent of VariableName.

VariableName is the user-facing key used at runtime to look up values in the ParameterBlock / RuntimeDataBlock, but the editor needs a separate identity that survives renames so existing Get/Set variable graph nodes can follow a variable across a rename in the Details panel. The editor's UComposableCameraVariableGraphNode tracks its variable by this GUID, and the toolkit populates a missing GUID lazily on load (see UComposableCameraTypeAsset::PostLoad).

This field is never read by the runtime — it exists purely for editor identity tracking and serialization round-trip.

VariableName¶

FName VariableName

Name of this variable.

Serves both as the runtime lookup key (ParameterBlock / RuntimeDataBlock) and as the display label in the graph editor context menu and on Get/Set variable nodes. There is no separate DisplayName — the FName IS the display name. Renames are tracked via VariableGuid so existing Get/Set graph nodes follow the variable through edits in the Details panel.

VariableType¶

EComposableCameraPinType VariableType = 

StructType¶

TObjectPtr< UScriptStruct > StructType = nullptr

EnumType¶

TObjectPtr< UEnum > EnumType = nullptr

For VariableType == Enum: the specific UEnum this variable represents. Stored internally as a normalized int64 (matching Enum pin behavior).

InitialValueString¶

FString InitialValueString

Initial value at camera instantiation (serialized string).

bResetEveryFrame¶

bool bResetEveryFrame = false

If true, the variable resets to InitialValue at the start of every frame (before node execution). If false, the variable persists across frames.
