It would be great to have an integration guide in the future for using any of the GameWorks libraries with the engine. It always sucks working with little to no documentation on those types of tasks.
But it would be fantastic if Epic could somehow distribute and license GameWorks with the engine, maybe as a “PRO” version like with Unity. I think a few extra dollars a month or an addition to the royalty would be a price developers would pay to have the tech integrated and ready to go. We are looking into hair and curve rendering solutions now, HairWorks could be just the ticket, and maybe cheaper than putting a small dev team on the task.
