SceneAssetsSubBuild
Do you want to build scene assets into Assetbundles separately?
Features
-Serialize scene assets.
-Label assets name and variant automatically.
-Build scene into small AssetBundles and load them dynamically and automatically.
How does it work?
It is an open-source project.But if you want to support us, you can buy one in Unity AssetStore
That will be very useful.
I have already made something like that for myself.
It lets me export currently opened scene or scenes selected in Editor.
It works like a hack, because it unlabels all the assetbundles except the selected ones, builds assebundles, and labels the unlabelled assetbundles back.
I have projects with over 100 scenes and had to wait until all get rebuilt when needed just one newly added scene before.
