When upgrading to corona 9, scenes with interior lights and .ies files don't work. I have tried loading the .ies files again and the result is the same. Does not render the lights.
MacOs Montery, Apple M1 Max, C4d R25 and 26, Corona 9.
When installing Corona 8, the lights do straighten.
Still in Corona 9 the core usage problem in apple M1. Same scene in intel 990% use cores and 600% in M1. Activating power saving on M1 if it uses 990% of the cores but after 15 min it returns to 600%.
Please look at this. Thank you and greetings.
