Old Twinmotion 2022 Trailer, where can I find this feature?!

Ok, so earlier today I randomly watched an old TM trailer for its 2022.1 release. Between 1:41-1:48 on the video, some sort of volume-bounded effect is applied to foliage and a decal is applied to a tree. I'd like to think I've got a pretty good knowledge of TM, and have never seen whatever this volume-bounded effect is (unless its a reflection probe?) and I am unable to apply decals to trees. I'd really like to know how to do this, if anyone has an understanding of what these features are and could shed some light on it, I'd really appreciate it.

Check the video out here:

I recall seeing that moment in that trailer too. It was around the time when I wanted to change the bark color of a tree, so it looked like a promising solution. Sadly, no further information - hopefully someone from Epic will see this and comment.
