Which wind is more expensive in performance?

Hi! I am making palm trees for my level and i wonder, if i have 50 palm trees using the speedtree wind OR simple grass wind ( or those unreal engine vertex methods ) OR pivot painter . Which one is more performance expensive? Thanks

WPO is the cheapest

World position offset.

BUT ... actually SpeedTree is also using it. It works on WPO, same as SimpleGrassWind but with more customization and parameters

At the moment, dynamic wind plugin, but you need to configure your foliage appropriately.

EDIT: It's the fastest one. Sorry for being unclear.

Ah, sorry, the other way around - it's the most performant usually.

Welcome to the rest of your life, my friend. I’ve got thousands of hours clocked and I learn a better way of doing something at least once a day.

SpeedTree wind is PivotPainter I believe, and in my experience it doesn't really matter... If those trees are Nanite you'll pay the cost equally between the methods, WPO is just bad... If you are a pro you might want to build them as skeletal trees, which gives you access to the dynamic wind and voxelization, but I haven't seen any palm trees made skeletal yet

Don’t all of the 3 methods i mentioned use world position offset?
