Seed Selector

Documentation

• Class name: SeedSelector
• Category: Art Venture/Utils
• Output node: False

The SeedSelector node is designed to select a seed value for procedural generation tasks, allowing users to switch between random and fixed seed modes. This flexibility enables both reproducibility of results with a fixed seed and the generation of varied outcomes with random seeds.

Input types

Required

• mode
  • Determines whether the seed selection is random or fixed, impacting the reproducibility and variability of the generated outcomes.
  • Comfy dtype: BOOLEAN
  • Python dtype: bool
• seed
  • The seed value used when mode is set to random, influencing the procedural generation process.
  • Comfy dtype: INT
  • Python dtype: int
• fixed_seed
  • The seed value used when mode is set to fixed, ensuring reproducibility of the generated outcomes.
  • Comfy dtype: INT
  • Python dtype: int

Output types

• seed
  • Comfy dtype: INT
  • The selected seed value, either fixed or randomly determined based on the mode, used for procedural generation.
  • Python dtype: int
