# Trellis2TextureStage - ComfyUI Built-in Node Documentation

> This node sets up the texture-stage sampling pass for Trellis2 generation.

This node sets up the texture-stage sampling pass for Trellis2 generation. It reads the coordinate layout and the per-voxel shape latent from the incoming shape latent, builds an empty sparse latent with 32 channels at the same coordinate layout, and attaches the required texture-stage metadata to the conditioning.

## Inputs

| Parameter      | Description                                                                                                                                                                                                                             | Data Type    | Required | Range |
| -------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------ | -------- | ----- |
| `positive`     | The positive conditioning used for the texture-generation pass. Texture-stage metadata is attached to it.                                                                                                                               | CONDITIONING | Yes      | -     |
| `negative`     | The negative conditioning used for the texture-generation pass. Texture-stage metadata is attached to it.                                                                                                                               | CONDITIONING | Yes      | -     |
| `shape_latent` | The latent dict produced by Trellis2ShapeStage or Trellis2UpsampleStage. It must contain `coords` (the coordinate layout, shape \[N, 4]) and `samples` (the per-voxel shape latent); `coord_resolution` and `model_frame` are optional. | LATENT       | Yes      | -     |

Notes:

* `shape_latent` must be the output of Trellis2ShapeStage or Trellis2UpsampleStage; it provides the coordinate layout and the per-voxel shape latent used by the texture pass.
* The coordinate layout is validated: batch ids in the first column of `coords` must be non-negative and contiguous, and the total row count must match the coordinate counts.
* When `positive` carries a projection feature pack (Pixal3D conditioning) and `shape_latent` includes `coord_resolution`, projection features at 1024 texture resolution are computed and attached to the conditioning.
* The model frame is read from `shape_latent`; when absent, it defaults to `"y_up"` if projection features are present and `"z_up"` otherwise.

## Outputs

| Output Name | Description                                                                                                                                                                                                                                          | Data Type    |
| ----------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------ |
| `positive`  | The positive conditioning with texture-stage metadata attached (generation mode, coordinates, coordinate counts, shape latent, model frame, and projection features when applicable).                                                                | CONDITIONING |
| `negative`  | The negative conditioning with the same texture-stage metadata attached.                                                                                                                                                                             | CONDITIONING |
| `latent`    | A new empty sparse latent with 32 channels at the same coordinate layout as the incoming shape latent. Its dict includes `samples`, `type` ("trellis2"), `coords`, `coord_counts`, and `model_frame`; `coord_resolution` is included when available. | LATENT       |
