# VaeDecodeStructureTrellis2 - ComfyUI Built-in Node Documentation

> This node converts Trellis structure latent samples into a 3D voxel grid using a VAE's structure decoder.

This node converts Trellis structure latent samples into a 3D voxel grid using a VAE's structure decoder. It reads only the first 8 channels of the latent, reconstructs the voxel occupancy, and adjusts the output resolution to either 32 or 64 as requested.

## Inputs

| Parameter    | Description                                                                                                                                         | Data Type | Required | Range          |
| ------------ | --------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | -------------- |
| `samples`    | The latent representation of the structure to decode. Only the first 8 channels of the latent are used for decoding.                                | LATENT    | Yes      | -              |
| `vae`        | The VAE whose structure decoder converts the latent into a voxel grid. Decoding is performed in batches.                                            | VAE       | Yes      | -              |
| `resolution` | The target spatial resolution of the output voxel grid (default: "32"). If the decoded grid has a different resolution, it is downsampled to match. | COMBO     | Yes      | "32"<br />"64" |

Note: When the decoded voxel grid resolution differs from the selected `resolution`, the grid is downsampled using 3D max pooling to the requested size.

## Outputs

| Output Name | Description                                                                                                                                             | Data Type |
| ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- |
| `voxel`     | A binary voxel occupancy grid as a float tensor with shape \[batch, depth, height, width]. Values are 1.0 for occupied voxels and 0.0 for empty voxels. | VOXEL     |
