Fraz : Thanks dude ! I don't really understand what you mean by generic ? that means too static ? not enough dynamic ? I need your help !!!
So today, I studied light, it was difficult, but i learned a lot ! Anyway, i need more practice at it ! Here are some sphere exercises ! It's really helpful, and i advice you to do them, it's really helpful to apply what you learned about light !
For the first one, I sucked up the cast shadow ! And for the second one, i sucked up the sky light ! really difficult !
