ComfyUI T2I Apply Style Node (only SD 1.5)

Simple node for ComfyUI that applies a text-to-image (T2I) style to an image or embedding with support for start/end frame control and a weight parameter.

Features

• Apply a style (image or embedding) to the target image or embedding.
• Start / End support: limit the style application to a frame range (useful for animations or frame sequences).
• Weight: control the strength of the style application (0.0 = no effect, 1.0 = full effect).

Inputs

• Image/Input — the image or embedding to be styled.
• Style — style source (image or style embedding).
• Start — start frame or step (inclusive) where the style begins applying.
• End — end frame or step (inclusive) where the style stops applying.
• Weight — float (0.0–1.0) controlling style strength.

Outputs

• Styled — the resulting image or embedding with the style applied according to the specified range and weight.

Usage

1. Add the node to your ComfyUI flow.
2. Connect the target Image/Input and the Style source.
3. Set Start and End to control which frames receive the style (leave blank or set to full range to apply globally).
4. Adjust Weight to blend between the original and styled outputs.

Notes

• When using for animations, ensure frame indices match your sequence indexing (0-based vs 1-based depending on your pipeline).
• If Start > End, the node will skip applying the style.
