Yeah i will switch to 4.4.
Must Support Epic, because Epic Supports my time as a kid with UT99

I think it´s less Crisp.
Question about Cavity:
Must i Multiply or Overlay the Cavity in the AO, or is there a way to plug a Cavity into a Slot directly in UE4?
Edit:
Must go sleep now.
In Germany its 2:30 AM 
Will read later answers!
Thanks all!
You have helped me very much
