ModelPass(ModelPassThrough)
This node technically implements a 'pass-through' function, which accepts an optional input of type MODEL and ensures that a MODEL type output is returned regardless of whether the input is present.
Model Pass Through
The ModelPass node technically implements a "pass-through" function that accepts an optional MODEL type input and ensures that a MODEL type output is returned regardless of whether the input exists.
The ModelPass node is a simple pass-through node whose core function is to receive a model input and output it as-is. It is primarily used to address connection limitations of certain nodes within workflows and does not modify or process the model in any way.
Node Function
This node technically implements a "pass-through" function that accepts an optional MODEL type input and ensures that a MODEL type output is returned regardless of whether the input exists. Its internal logic merely passes the input parameter directly to the return value, without involving any data conversion or processing mechanisms.
Node Parameter Description - ModelPass
Connection Inputs (Inputs)
| Parameter Name | Data Type | Required | Default Value | Value Range/Options | Description |
|---|---|---|---|---|---|
model | MODEL | No | - | - | Output parameter model: Outputs the same MODEL data as the input. Used to pass the model to downstream nodes. |
Output
| Parameter Name | Data Type | Description |
|---|---|---|
| model | MODEL | Output parameter model: Outputs the same MODEL data as the input. Used to pass the model to downstream nodes. |
Usage Scenarios
In practical workflows, when you need to connect model data to nodes like "Set" that do not allow bypass inputs, you can use this node as an intermediary. For example, in a conditional branch flow, you can first connect the model to the ModelPass node and then connect its output to subsequent processing nodes, thereby bypassing connection restrictions.
Notes
This node itself has no processing functionality and is only used as a data channel, so it does not alter any properties of the input model. When using it, ensure that the upstream node provides valid MODEL data.
