Material ambient occlusion does not work with the skylight set to movable. Setting the material to allow static lighting will fix the issue until the level is reloaded.

Found in 4.19 CL# 4033788, 4.20 CL# 4233996, 4.21 CL# 4234136

Steps to Reproduce
  1. Open attached project
  2. Open "AOTest_Inst" and enable the override parameter and change its to any value between 1 and 0
  3. Change both the skylight and directional light to stationary
  4. Repeat step two

The ambient occlusion will not be present while the lights are set to movable but works with it set to stationary or static.

The ambient occlusion would show the same regardless of the mobility setting set in the skylight or directional light
