I am a 3d animation lover. And there's a lot of questions i want to ask about 3d. I am studying 3d max now, but there are a lot of questions which i still don't have a n answer for them. First question: Is there any webpage which can teach us more about 3d animation or 3d max? Second question: What kind of softwares i need to have in my computer , if i wanna be a 3d professional? Third question: How many RAMs, what CPU, and what kind of acessories i need to install in my computer to produce a good animation? Because everytime when i render my movie, it takes days to render a 30 seconds movie. Fourth question: Everytime when i render a movie with "mental ray" effect and " Mental ray shadow map", i see an undesiderable shadow on the object. I dunno how to remove that shadow. Fifth question: When should i use " Advanced ray traced shadow "? in 3d max? Thank you very much~
