This answer indicates that it's a missing feature, but I see it more as a major bug.
FOV, ambient light and exposure is controlled by the patched 'camera' but does not play back! In addition patched smoke does not play back either.
As the values are reset when removing DMX in I had to experiment with values to be able to render my movie. Luckily I had no change in these parameters during the movie!
PS. I just tried the IOS app with the same file but could not find where to adjust the necessary settings there. Is it at all possible?
