RenderWithShader not working in built 5.3.1p3

So, I have an additional camera that renders depth texture, it uses custom shader that outputs depth in 32 bit float format using encoding. IT"S WORKING GREAT IN EDITOR! But in built version output texture is just a render of the scene, custom shader not used. Tried using simple shader that outputs white color and still got the same result. Tried to set forward rendering path for that camera - no effect. Is it expected behaviour or is it a bug in Unity?

Anyone? Has no one encountered this behaviour?

Found what was wrong. I didn’t knew that Shader.Find not working in built if shader not put into Resources.
