Orthographic Scene Depth capture does not work on mobile

Hi!

I was trying to make my own stylized shader, so I needed to render my own shadows (as Unreal just do not allow to use light info in materials/custom nodes). For cascade shadows I need an orthographic depth of my scene. But the problem is that orthographic scene depth capture does not work on mobile devices.

I’ve made a simple project to visualize it:

Android:

Editor:

So, as you can see, orthographic scene depth just does not work and outputs black texture. But perspective works as expected. Editor have both of them working, ofcourse.

Thank you!
