What did unity's Animation Compression options optimal do?


  • Optimal: Let unity decide how to compress. Either by keyframe reduction or by using dense format. Unity will pick the most optimal of the two.

Who knows the algorithm of the dense format? What’s the differences between stream data and dense data?

I wrote in as many details as I could about this on my blog here: Animation Compression: Unity 5 · Nicholas Frechette's Blog
