Hi Guys,

Lately I have been ran into some issues when trying to integrate Tone-mapping into our Oculus-VR project. We are currently on the 5.5 Oculus VR fork but with the Mobile HDR turned off for bettery performance. 

My question is, the post-processing volume doesn't seem to be working even I execute the following command:

r.Mobile.TonemapSubpass=1

Unreal Tone Mapping for Oculus 

the post processing doesn't seem to be affecting the scene. And when I turned on the Mobile HDR the Post processing start to work.

So I wonder if the ToneMap Subpass requried to have the Mobile HDR On or am I doing something wrong?

Oh I have firgured it out! Sometimes executing the command directly from the inside of the editor cosole won't work, you will need to add a line of code in the DefaultEngine.ini file

r.Mobile.TonemapSubpass=1

And that I believe will solve the problem!
