I’ve set up occlusion on the auto tiles for the walls, saved the tile map, and enabled Shadow on the torch but I get some unusual looking shadows. The programmer in me wants to show code snippets but in times like this there’s no code to show. 
Well that was dumb of me! Had I just continued with the video I would have learned that I needed to set the Occluder Offset to 0,0 in the Autotiles!
I’ll leave this shameful mistake to help others just in case. Mark this question answered
