ScriptedImporter textures always display as opaque #64

Closed hybridherbst closed 1 year ago

The regular texture importer is able to show textures as opaque or transparent based on the "alphaIsTransparency" option; however, it seems that textures are always displayed as opaque (with separately selectable A channel) in the KtxImporter textures.

Regular texture importer for same file shows transparency image

Thanks for reporting!

Good news: Doing this in KtxImporter.OnImportAsset seems to bring the checkerboard background.

result.texture.alphaIsTransparency = true;

On regluar TextureImporters this would not only show the checkerboard/alpha blending, but enable some color filtering (see details), but I assume it does not apply here.

So I assume this does no harm and I'd simply go with this solution.

Or do you think there has to be a dedicated checkbox in the settings?

Oh, great if that's all that's needed :)
