Artificial Cheese

I just realized that I said right instead of left. I'm amazing when it comes to forums. And it's probably not a good suggestion either. After taking a closer look, it seems that DDS has a lot more options than could be worth implementing.

As the title says, I want to create DDS images with custom mipmaps only using Paint.net. This could be done by using layers in a similar way to how animated images can be made. For example, we have a 512x512 image, then we import an image half that size with whatever we want the next mipmap to be as a seperate layer. Then we have a 256x256 texture in the top right corner of the image while still retaining the 512x512 canvas size. If there's already a plugin that does this, then please tell me.
