In Unity Packages there is a tool to import PSD files: https://docs.unity3d.com/Packages/com.unity.2d.psdimporter@1.2/manual/index.html
But I can't find this package in my Unity Package Manager (Window -> Package Manager).
How can I install it?..
Currently using Unity 2019.1.0f2 if matters.
PSD Importer is still in Preview
state (see Packages documentation).
→ You have to enable Show Preview Packages in the Advanced menu of the PackageManager
window
