The only two-pass outliner for UE4
Everyone knows the two-pass outlining technique. However, there had been no good implementation in UE4, because multi-pass shading materials are not supported. We introduce AllPlatformOutlinePack, the UE4 specific two-pass outlining implementation, which bypasses the limited freedom of UE4 shading pipeline. It was challenging to implement it. But fortunately, it runs perfect and is very easy to use.
