I've been asking for this for so long... but in the end I made a few modifications to official Fade behavior.
Called it "Fade Adv" from lack of better ideas xD
EDIT: You can now download it from here Fade Adv
If you downloaded previous version, then please delete it and redownload it from that page I've posted here - This is a proper 1.0 version with all extra things that was not present in ma previous upload
It's all super simple but this small modifications helps and speed up things a lot !
I really would like that Ashley could add this to official plugin as well. I'm not a plugin/behavior creator and it took me only about 15 minutes to understand, add and test all of this this, so Ashley could probably do this in 3 with eyes closed
