I just got back from vacation last week and was planning to take a stab at migrating the stuff over this week.

No promises though, as for some reason I am having a bug that is causing the twist value to be incorrect causing a seam between all branches. I had fixed that bug at one point so I am not sure why it crept back in.

re: WorldPosition vs Z offset.

The worldpostion would be the incoming worldposition minus the Zoffset times the VertexNormal.

So OffsetWorldPos = StartWorldpos - (Zoffset * vertexnormal)

And yes, material optimizations were in 4.11.

Welcome back, Thanks for taking a stab at it! fingers crossed you squash the bug as this is a really handy blueprint
