I created a room that uses mixed lighting; baked AO for static objects and real-time for non-static, obviously. Whenever I turn the directional lighting a certain angle, then I move the camera into a certain position, my baked AO leaves. It definitely must be the directional light, because when I uncheck the lighting to be off, my baked AO displays properly.
The only way I can make this stop WITH the directional lighting still on is if I point the directional light straight down, but this isn’t wanted because I prefer the player’s shadow to be at an angle so that it can be seen better.
In the picture below, you see that only moving slightly from the “Good” spot will result in the “Not Good” spot. The “Not Good” spots change depending on how I angle the directional light. Very weird!

I can’t seemed to figure this out!
Edit: After messing around, I found that decreasing the strength displays the AO. Kinda weird that this effects the baked AO, or not.
