UE4 4.11 Multires Documentation?

Hi!

I am currently trying to find out how to actually use the Unreal Engine 4.11 multiresolution rendering integration however there does not seem to be any information about it out there.

I found a GDC presentation where some console commands of the 4.10 integration are mentioned - but they do not seem to work with 4.11.

So how can I set the SplitInset and DensityScale in 4.11?

Thank you
Jannes
