Not knowingly use Beta technology without considering the fact it is Beta at best?
Aside from that, surely a system to exclude the rendering of meshes which require WPO is already in place.
Its sort of unthinkable that just by enabling a beta feature you end up loosing the ability to manipulate the verts.
It implies that any project using the same option won’t be able to have animated foliage, or support SpeedTree.
So either there already is a way to use both, or a way will eventually be made avaliable when the item is sligtly less “beta”.
Either way it doesn’t have much to do with tessellation itself.
