I also think that something is wrong with the cage in the latest version of SP.
The last version I used before switching to the 2017.3.0 was 2.6.1 and it worked fine.
I installed the latest version yesterday and I tried to bake a very simple normal map using the settings I used in the 2.6.1 version but it didn't work.(Picture 1).
I changed the Max Frontal and Max Rear Distance a little bit, something I hadn't done before. I thought that it was ok after baking but I was wrong (Picture 2). In the iRay viewer it looks to me as if there was no cage used during the baking process (Picture 3).
