# Trellis2UpsampleStage - ComfyUI Built-in Node Documentation

> This node takes the 512-resolution shape latent produced by the first shape-stage sampling pass, upscales it to a higher target resolution, and prepares the conditioning and latent

This node takes the 512-resolution shape latent produced by the first shape-stage sampling pass, upscales it to a higher target resolution, and prepares the conditioning and latent needed for the second shape-stage sampling pass. It attaches per-stage metadata to the conditioning so the model can use it during generation.

## Inputs

| Parameter           | Description                                                                               | Data Type    | Required | Range                  |
| ------------------- | ----------------------------------------------------------------------------------------- | ------------ | -------- | ---------------------- |
| `positive`          | The positive conditioning to which the upsampling-stage shape metadata is attached.       | CONDITIONING | Yes      |                        |
| `negative`          | The negative conditioning to which the upsampling-stage shape metadata is attached.       | CONDITIONING | Yes      |                        |
| `shape_latent`      | The 512-resolution shape latent output from the first shape-stage KSampler.               | LATENT       | Yes      |                        |
| `vae`               | The Trellis2 VAE used to decode the shape latent into high-resolution sparse coordinates. | VAE          | Yes      |                        |
| `target_resolution` | Voxel resolution of the upsampled shape. Higher = more detail, more VRAM. Default: 1024.  | INT          | Yes      | 1024 - 2048 (step 128) |

## Outputs

| Output Name | Description                                                                                                                                                | Data Type    |
| ----------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------ |
| `positive`  | Positive conditioning with the upsampling-stage shape metadata attached.                                                                                   | CONDITIONING |
| `negative`  | Negative conditioning with the upsampling-stage shape metadata attached.                                                                                   | CONDITIONING |
| `latent`    | Zero-filled latent prepared for the second shape-stage sampling pass at the target resolution, carrying the upsampled coordinates and resolution metadata. | LATENT       |
