# CLIPTextEncodeSD3 - ComfyUI Built-in Node Documentation

> CLIPTextEncodeSD3 processes text inputs for Stable Diffusion 3 models by encoding multiple text prompts using different CLIP models.

CLIPTextEncodeSD3 processes text inputs for Stable Diffusion 3 models by encoding multiple text prompts using different CLIP models. It handles three separate text inputs (`clip_g`, `clip_l`, and `t5xxl`) and provides options for managing empty text padding. The node ensures proper token alignment between different text inputs and returns conditioning data suitable for SD3 generation pipelines.

## Inputs

| Parameter       | Description                                                                                                                                                                                                                                                                                                                 | Data Type | Required | Range                          |
| --------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ------------------------------ |
| `clip`          | The CLIP model used for text encoding                                                                                                                                                                                                                                                                                       | CLIP      | Yes      | -                              |
| `clip_l`        | Text input for the local CLIP model. Supports multiline text and dynamic prompts.                                                                                                                                                                                                                                           | STRING    | Yes      | -                              |
| `clip_g`        | Text input for the global CLIP model. Supports multiline text and dynamic prompts.                                                                                                                                                                                                                                          | STRING    | Yes      | -                              |
| `t5xxl`         | Text input for the T5-XXL model. Supports multiline text and dynamic prompts.                                                                                                                                                                                                                                               | STRING    | Yes      | -                              |
| `empty_padding` | Controls how empty text inputs are handled. When set to "none", empty text inputs for `clip_g`, `clip_l`, or `t5xxl` result in empty token lists instead of padding. When set to "empty\_prompt", empty inputs are tokenized as empty prompts (standard padding behavior). This is an advanced parameter (default: "none"). | COMBO     | Yes      | `"none"`<br />`"empty_prompt"` |

**Parameter Constraints:**

* When `empty_padding` is set to "none", empty text inputs for `clip_g`, `clip_l`, or `t5xxl` result in empty token lists instead of padding
* The node automatically balances token lengths between `clip_l` and `clip_g` inputs by padding the shorter one with empty tokens when lengths differ
* All text inputs support dynamic prompts and multiline text entry
