Saving Model Creates PNG Images

[SpiderPig]

When saving this model in the asset editor it automatically generates PNG files even though everything is DDS.

Yes, that is correct.  glTF file require PNG or JPEG images. DDS is supported as an extension, but to remain compatible with other loads a copy of the image is included in PNG format:

One of the goals of Ultra is to make sure all your models can always be loaded back into your modeling program and edited. Models are never locked / destroyed / finalized. When your game is distributed you will probably just want to not include the PNG files.

Okay, thanks 🙂
