# Thumbnails & Visual Exports

Cached previews, generated thumbnail files, still images and GLB export

Durty Cloth Tool can render your clothing in four different ways. They look similar but serve different purposes, so it is worth knowing which is which.

| What                       | Where it appears                              | License  |
| -------------------------- | --------------------------------------------- | -------- |
| **Cached previews**        | Inside DCT, in the drawable and texture lists | Free     |
| **Thumbnail Generator**    | Image files written to a folder you choose    | Ultimate |
| **Still image generation** | Rendered images of clothing variations        | Ultimate |
| **GLB export**             | 3D model files for other tools                | Ultimate |

## Cached previews inside the app

Projects can show a small thumbnail beside each cloth drawable and texture variation, plus a larger preview when you hover one.

New projects have this enabled. An existing project can opt in with **Show thumbnails in the drawable and texture lists** under **Thumbnails in the lists:** in the Project Settings.

* Previews are generated in the background, starting with the first valid texture of each drawable.
* Drawable thumbnails update after you reorder items.
* The cache is disposable. You can clear it and let DCT rebuild it at any time.
* **Size in lists:** adjusts the thumbnail size from 24 px to 64 px, and **Hover preview size:** the larger preview from 64 px to 512 px.

{% hint style="info" %}
These previews are free and stay inside the application. Writing thumbnail **files** to disk requires an **Ultimate** license.
{% endhint %}

## Thumbnail Generator

Found under **Project > Project Actions**, the Thumbnail Generator writes thumbnails for the whole project into a folder you choose, and keeps that folder in sync as your clothing changes.

Configure the output folder, image format, background, camera, scope and naming template, then either regenerate everything or sync only what changed. Advanced options, including custom camera settings and per-type overrides, remain visible but read-only without an active Ultimate license.

* The generator previews its plan before it writes anything.
* Progress is cancellable and shows the remaining time.
* If a replacement fails, the earlier file is kept rather than lost.
* It **never removes a file it did not create**, so the folder is safe to share with other content.

## Still image generation

Render clothing variations as finished images, individually, per drawable, or across the whole project. The Project Settings control transparency or a background colour, edge trimming, image size, camera view, naming, and whether existing files are skipped in a batch. Project wide runs show cancellable progress.

## GLB export

Export clothing variations as GLB models for use in other 3D tools. DCT pairs each readable non dummy model with its selected texture variation and uses GTA style output names. Missing or invalid inputs are reported rather than silently skipped, and project wide exports can be cancelled.

## When rendering does not work

Rendering uses a browser component. DCT uses a suitable installed **Microsoft Edge** or **Google Chrome**, or a browser it downloaded earlier, so those paths work offline. If none is available, DCT downloads Chromium automatically on first use. That first download needs an internet connection; you do not need to install a browser manually.

{% hint style="warning" %}
If the automatic browser download fails, check your connection and retry the export. Advanced users can also point the `DCT_CHROMIUM_PATH` environment variable at an existing compatible browser executable.
{% endhint %}

Computers without a working graphics driver fall back to software rendering automatically, which is slower but works.

{% hint style="info" %}
Clothing whose diffuse texture is fully transparent, which is common for torso and Body drawables, is captured again with transparency disabled so the colours still show. Only geometry that is deliberately invisible is reported as having nothing to show.
