FlowMatch Euler Discrete Scheduler for ComfyUI

FlowMatchEulerDiscrete seems not exposed in comfy, but it is what the official demo in diffusers use. So I am exposing it in the scheduler section and provide a node, experimental, to configure the scheduler for use with CustomSampler So...if you want sharper and more noise free images, you can experiment with this.

Installation

this is an alpha stage node, so not esposed yet in manager. to install open a terminal command in your custom nodes then, you do have git installed I assume, then...:

git clone https://github.com/erosDiffusion/ComfyUI-EulerDiscreteScheduler.git

Custom node that exposes all parameters of the FlowMatchEulerDiscreteScheduler. Outputs SIGMAS for use with SamplerCustom node.

Usage

1. Add FlowMatch Euler Discrete Scheduler (Custom) node to your workflow
2. Connect its SIGMAS output to SamplerCustom node's sigmas input
3. Adjust parameters to control the sampling behavior

Example Workflow

Model -> SamplerCustom
         ^ 
         |
         FlowMatch Euler Scheduler (steps=30, use_karras_sigmas=True)
