RevitGary Posted February 28, 2010 Share Posted February 28, 2010 I am fairly new to mental ray although I think I have got it figured out. I am very new to animation. My question is how can one even do animation with mental ray? It takes a couple hours to render one image. How do you get around this when trying to do 28 frames per second?

Crazy Homeless Guy Posted February 28, 2010 Share Posted February 28, 2010 Eliminate all glossy reflections for your animation, and make sure your detail is not to small, otherwise you will need to crank up the AA to obscene levels in order to keep the animation from dancing. If you do need glossy on something, I would render it in a separate pass with a subset scene shader. I have not done a lot of animations in Mental Ray, but those tips should help.

Justin Hunt Posted February 28, 2010 Share Posted February 28, 2010 Are these "Couple of hours" at video resolution or print resolution? 5 to 20 minutes per frame is average. Read up on the new FG calculation for animation methods, they are great and have literlary saves me hours of calculation time. jhv Link to comment Share on other sites More sharing options...
RevitGary Posted February 28, 2010 Author Share Posted February 28, 2010 I know a bit about the final gather settings doing them every 10th frame or something I'll study that more. What is a good resolution for animation? Link to comment Share on other sites More sharing options...
maciejwypych Posted March 1, 2010 Share Posted March 1, 2010 I know a bit about the final gather settings doing them every 10th frame or something I'll study that more. What is a good resolution for animation? what it's for? dvd? internet? presentation? Keep in mind that every second of extra render time per frame get's multiplied by number of all frames, so don't render higher res than you really need. For FG you can use Project Points along camera path, but it's good only for quite short animations or when there is no quick camera movement. It's good because you need to calculate 1 frame to save fg, so it's quick. Otherwise render fg for every 10 frames, save it, lock it and then render final full sequence. If you have people or cars moving, you need to render them on separate pass!!!!! otherwise you'll have flickering effect. Hope that helps. Link to comment Share on other sites More sharing options...
RevitGary Posted March 1, 2010 Author Share Posted March 1, 2010 what it's for? dvd? internet? presentation? I have no specific project currently I just want to learn how its done. So I was asking basic questions to get started. What resolutions would you use for the list above. Link to comment Share on other sites More sharing options...
maciejwypych Posted March 1, 2010 Share Posted March 1, 2010 DVD - 720/704×480 (NTSC) or 720/704×576 (PAL) at 29.97, 25, or 23.976 FPS HDTV - is typically 1280x720 or 1920x1080 Internet - If you are planning to put your animation on ytube or similar then, recommended settings are: H.264, MPEG-2 or MPEG-4 format 640x480 (SD) or 1280x720 (HD) for 4:3 & 16:9 aspect ratios. Presentation- Projectors for office use have usually 800x600 Link to comment Share on other sites More sharing options...
RevitGary Posted March 1, 2010 Author Share Posted March 1, 2010 HDTV - is typically 1280x720 or 1920x1080 Wow I guess I will not do any HD any time soon that could take forever without a render farm. Link to comment Share on other sites More sharing options...
