Two images, one light the other dark. Materials, light sources and render settings did not change.
The only thing that has been done is to apply the modifier (extract and separate) to polygons on the floor(after that changes, rendered image became darker). CoronaSurface applied to the entire scene. This is the second time with this scene.
For the first time Directional Light ceased to illuminate the object that has been modified (extract and separate).
----------
every time when I try to create a CoronaVolume, CoronaRaytype or CoronaLight in the Hypershade
I get an error in the script editor:
# Error: line 1: object of type 'CoronaRaytype' has no len() #
and after that in the attribute editor disappear the vertical scrollbar, and all the settings are located below the screen become invisible.
