Question When select texturetype to sprite, duplicate assets in bundles, How to solve?

Unity version:2020.3.23f1

Ready: a picture and a RawImage Prefab dependent on the picture


A Build Script:
public static class BuildAssetBundle
{
[MenuItem("BuildAssetBundle/Start")]
static void Build()
{
List<AssetBundleBuild> assetBundleBuilds = new List<AssetBundleBuild>();

AssetBundleBuild textureBundle = new AssetBundleBuild
{
assetBundleName = "texture.unity3d",
assetNames = new string[]{
"Assets/Texture/texture.jpg",
}
};
assetBundleBuilds.Add(textureBundle);

AssetBundleBuild prefabBundle = new AssetBundleBuild
{
assetBundleName = "prefab.unity3d",
assetNames = new string[]{
"Assets/Prefab/RawImage.prefab",
}
};
assetBundleBuilds.Add(prefabBundle);

BuildPipeline.BuildAssetBundles(
"AssetBundles",
assetBundleBuilds.ToArray(),
BuildAssetBundleOptions.ChunkBasedCompression | BuildAssetBundleOptions.AppendHashToAssetBundleName,
EditorUserBuildSettings.activeBuildTarget
);
}
}

First:Build with default texture type

this is what i want:


Second:Build with Sprite type:
(Delete all assetBundles file, rebuild here)



the texture is include in the prefab bundle!!! And when I load the RawImange GameObject, it will use the prefab bundle's texture, i change the texture(sprite type) and build the bundle will not show correct, because build assetbundle only change the texture bundle.

and when I change to default type and build again(this time not delete the bundles), the prefab bundle doesn't change back to small size, because the dependies is the same.

Is it normal ? or it is a bug?

How to solve this?

Thanks.

 

I test Scritable Build Pipeline with (CompatibilityBuildPipeline.BuildAssetBundles) and it has not problem

 

CompatibilityBuildPipeline.BuildAssetBundles confirm OK
