Uncorrected SceneDepth?

[anonymous_user_c0e54ce41 (anonymous_user_c0e54ce4)]

Hi there.

I’m trying to render SceneDepth to a texture with a post-process material, and I’m seeing some strange non-linearities in my depth values. I have two questions:

1. If I have a SceneDepth post-processing material (at the “replace tone mapping” location), are there still other affects which could affect depth measurements?
2. Is there a simple way (blueprint or C++) to extract a raw, untouched Z-buffer for a render target?

Thanks!
