Hi Tim,
Thank you for the confirmation! Great to know that I wasn’t seeing things 
Regarding the MaxLightsPerPixel overflow - I only set it to 1 for the visualization purposes in this case 
I did try, however, setting it to values lower than 8 to see if this is something that I can use for scalability - e.g. 16 MaxLightsPerPixel for Epic preset, 8 for high, 6 for medium and 4 for low. Unfortunately, setting it to 4 would result in the artifacting that you’ve seen in the video, thus my question. Still trying to wrap my head around SMRT scalability - I was thinking that MaxLightsPerPixel could be used together with decreasing the quality (ray count + sample count) of SMRT to still keep soft shadows on N amount of lights per pixel
