Has writing to RWTexture3D from pixel shader stopped working?

Unity Engine

I had been writing to a RWTexture3D from a pixel shader in an older version of Unity 5.x and it was working without problems. It doesn’t seem to be working any more in either Unity 5.3.4 or Unity 5.4. Can anyone verify that it is either working or not?

Ok, maybe i am not understanding something properly, I was using Gamma color space in player settings. I switched the color space to Linear, and magically the RWTexture3D started being written to. Changing the RenderTextureReadWrite mode on the RenderTexture object made no difference. I will investigate further.
