Important tip in rendering!
show user profile  cbflex
Hey guys,

As some of you have seen, I've been working on this scene

I had come across a huge problem during it. Rendering this image at a sampling rate of 1/4 - 4 in HD with 33 lights and mental ray shadow maps on, was literally taking me 9.5 hours per frame. It's a 1000 frame animation. Disregarding how large the animation is, the render time would be probably 6 months or more or something like that... just very long.
I ran many tests and I couldn't figure out what the problem is. I still can't figure it out, but I found another symptom, and the way to fix it, and I want to share it with you all incase some of you get this crazy problem.
My other symptom was that for some reason when I turn on scanline render with shadows on simple, it automatically turned off and auto volume turned on. And everytime i start the render, no matter how many times I change it back, it always by itself did that. When I ran another instance of max with just a teapot scene, it didn't do it. I then proceeded by setting everything I can in the render window to be exactly like the new teapot scene and the problems still occured.
I have no idea why this happened and why my render times were through the roof. I rebooted max and my computer and nothing worked. I began losing hope.
My very last attempt was simply to just load up the default rendering preset of mental ray with gi enabled. I loaded it up, and to my everlasting joy, scanline did not get disabled by itself, and the render speed was at 1 hour and 40 minutes per frame. Still a long time, but cmon, I shortened the time by like 70% or something just by reloading a preset.
So incase you all get this crazy shit which really pissed me off, bitch smack your computer and load the preset... worked for me :)
Happy Animating!
