Question Custom material importer

I am using ScriptedImporter for importing materials from custom format into unity, it works but resulting material properties are not editable. Any way to fix that?

 

That's intended and also how e.g. prefabs and materials created by the model importer work. When the importer runs again, it would have to overwrite or merge your changes, so instead Unity opted to make the imported objects read-only.

The idea is that you edit your custom material format instead of editing the imported result. If you do want to edit the generated material in Unity, you maybe want to create something other than a ScriptedImporter or add an option to extract the material and create a separate material asset, like the model importer is doing.

 

Thanks for answer.
My problem is that source material is not 1-to-1 into unity material, but is only a small subset of it, and rest of properties are to be tuned manually.

Anything specific?

 

You could make your source material more like templates, adding editor commands or some kind of UI to easily create new material assets based on it.

Or use AssetPostprocessor.OnPostprocessAllAssets to know when the source asset was changed, create an editable material as a sub-asset and then handle merging user and source changes yourself.

 

Okay, thanks.
