Constant (mtb)

Documentation

• Class name: Constant (mtb)
• Category: mtb/utils
• Output node: False

The MTB_Constant node is designed to output a constant value. It serves as a utility within a graph to provide a fixed value that can be used as input to other nodes, facilitating the creation of static or dynamic flows based on predefined constants.

Input types

Required

• Value
  • Represents the constant value to be output by the node. This parameter is essential for defining the static data that will be passed through the graph, affecting subsequent operations.
  • Comfy dtype: *
  • Python dtype: str | int | float | dict | list | bool | None

Output types

• output
  • Comfy dtype: *
  • The output of the MTB_Constant node, which is the constant value defined by the input parameter. This value is passed through the graph for use in subsequent nodes.
  • Python dtype: str | int | float | dict | list | bool | None

Usage tips

• Infra type: CPU
• Common nodes: unknown
