My issue is related to spot light rendering. When I turn on my computer for the first time and open a project file, the spot light works properly with medium effects. After I close this project and open another project file, the medium effect disappears completely, though the spot light can still illuminate objects clearly. Restarting Blender and OctaneRender afterward cannot bring back the medium effect at all.
