ImportOverrides

Unity's texture importer provide a list of default settings for manual editing. However, if you are trying to automate those importers, you need to go through

• TextureImporterSettings
• TextureImporterPlatformSettings

With those 2 structs, you would typically set them on the texture importer through an AssetImporter.

The issue

Setting up a scriptable import pipeline requires you know which settings to enable/disable. The struct just has a bunch of getter and setters and you'll need to know which settings to place. Without a visual GUI, this makes it cumbersome to visualize.

The solution

Provide a GUI similar to Unity's TextureImporter. This allows the TextureImporterSettings to feel more familiar and allows developers to set up their pipeline visually. That is what this repository aims to do.

On the left side of the screenshot is Unity's default TextureImporter. The right side of the screenshot aims to replicate that same GUI but for the TextureImporterSettings and TextureImporterPlatformSettings structs.

What this plugin does not do

It is still the developer's responsibility to set up their own Scriptable Import Pipeline. This is not an architecture, it is only a GUI frontend to the TextureImporterSettings.

You can use this GUI frontend for all instances of serialized TextureImporterSettings.

Usage

Use TextureImporterSettings normally in your project. Any serialized TextureImporterSettings will be displayed with a custom GUI in the inspector. When writing your custom importer, use the following APIs:

• TextureImporter.SetTextureSettings
• TextureImporter.SetTexturePlatformSettings

You can also use the TextureImporter's API to copy to the structs first if you want to use some of Unity's default per import session.

Limitations

Mipmap Limit Groups are not embedded in TextureImporterSettings, so the GUI does not display an override for that. Your Scriptable Import Pipeline should handle it.

In the demo folder, you can see a Scriptable Object called Demo.

• The Demo Scriptable Object only has the TextureImporterSettings variable. Instead of showing the default struct, it shows a GUI similar to the TextureImporter.
