comfydv

A collection of workflow efficiency and quality of life nodes that I've created for personal use out of necessity.

  • String Formatting: Use either plain python f-strings or more advanced Jinja2 templating to format outputs.
  • Random Choice: Add an abitrary number of inputs and then, with seed control, randomly select one for an output.

String Formatting

Python F-String

A simple python f-string dynamically creates the necessary inputs/outputs for the detected keys.

Jinja 2

Switching to Jinja2 allows you to use more advanced control blocks and other filters/features of that templating language. See Jinja documentation for further details.

Random Choice

Ability to take arbitrary length and type of inputs to then output a choice with a controllable seed.
