SpeedTree Wind Issue Workaround

So, i was pretty surprised when my instanced foliage trees were going crazy - with the leaves stretching like there was a black hole in the middle of my level. Note that this ONLY happens when the trees are part of instanced foliage.
I just found out that this seems to be related to the “WindType” option in the SpeedTree material node that controls the WPO of the branches and leaves. By default, it’s set to “BestPlus”. By dropping it down to “Better” or lower, the issue completely disappears.
