Question about Nvidia Ansel

So I have re-downloaded this wonderful game today to give From the Ashes DLC a try, but when I go to the Ansel mode I can no longer move camera through walls and stuff, i.e. the camera no longer ignores collision. It’s really bad, because I liked the way I could take pictures of Henry looking outside the window, etc.
How do I go about changing this to the same state it was when Ansel has only just become available for KCD??
