Is CustomDepth working on mobile using ES2?

Hello.

I’m try to apply transparency mesh with CustomDepth on UE4.16.2.

And I fixed SceneTextureLookup function.
(Pixel Depth not Working on Mobile when used with Custom Depth, Unreal Engine Issues and Bug Tracker (UE-44700))

It was good working when i run with -FeatureLevelES2 on PC.

But it doesn’t work CustomDeapth on mobile(iPhone7) using ES2.
