It would be nice for unity to work with PSD files directly. I am required to work with PSD files (cannot use PSB), but since Unity only imports PSB, I have to manually change my PSB back to PSD every time I want to do a modification, and change back from PSD to PSB once I'm finished.
I don't see any reason for Unity not to support this. All I'm doing is renaming my .psd file to .psb manually. It's the exact same file, so why can't unity just take that .psd instead.
Hmm... PSD files are supported by Unity. We have a lot of PSD files in one of our projects. You just have to drag and drop them on Unity.
It would be nice if Unity could add that. I'm still waiting on a million different promised features though, so I wouldn't hold my breath. I saw this addon the other day: https://assetstore.unity.com/packages/tools/utilities/psd-import-174441 Haven't tried it myself, but it might be useful if you really need the functionality.
