Two of my packages that works seprate or together perfectly
CineMaster is about creating AAA Cutscene level using only your inspector without the need to access the code by adjusting the values of a lot of attributes like animation sound videos and alot more , it works great with Cinemachine and unity Splines and timelines if there are an old cutscene made with timeline you can easily integrate it with the rest that was made with CineMaster
