Hi Christoufu!
Now I got the chance to test “Assets Cleaner” properly! It works as described, one remark though! If you have a Sequencer(s) - in your project and even if you use still use it in the project, the Assets Cleaner will include the Sequencer(s) on the “Clean list”. The good part is that the Sequencer(s) will be at the top of the “Clean list”, so it’s easy to see it and remove it from the “Clean list”. After that, you can confidently delete the “Clean list”.
Obs! I tried in both ways, with the Level I was working on open, and with a By Default Level open - as it is recommended. It worked both ways, so I didn’t notice the difference.
Great Tool!!!
