In general, when we want to generate and save an asset using the Component Builder, after clicking *Save to Disk*, a thumbnail is created inside the asset’s folder.
The issue is that the two files `.usda` and `.png` are saved with the generic name **thumbnail**. Then, when we try to load these assets via *Add Asset Directory*, since the thumbnails weren’t saved with the asset’s actual name, the system generates new thumbnails again for those assets.

This becomes a problem if we had already created our own custom thumbnail (for example, with a specific camera angle or lighting setup), because we can’t use that custom thumbnail in the Asset Gallery.

Interestingly, this issue does not occur when the asset has variations — in that case, all thumbnails are saved with their respective variation names. However, this problem remains for single (non-variation) assets.

To solve this, I went into the **Component Output** node and changed the **Override Output Image** setting in *Thumbnail Render*, as well as the **Output File** option in *Save Thumbnail Scene*. Instead of saving them as `"thumbnail.png"` and `"thumbnail.usda"`, I replaced them with:

```
chs("../rootprim") + "_Thumbnail.png"
chs("../rootprim") + "_Thumbnail.usda"
```

This way, both files are saved with the asset’s actual name, preventing issues when loading them back into the Asset Gallery.

I just wanted to report this so that the dev team could make a small fix for it.
