dmtr Posted February 26, 2009 Share Posted February 26, 2009 Hi guys, I'm working on the house project and whenever I'm trying to render this in high res 4096x2458 I have black areas on my final render. Image below shows what I mean. Smaller sizes works ok. Does anyone has idea how can I avoid it and get good quality image? thanks. Link to comment Share on other sites More sharing options...

STRAT Posted February 26, 2009 Share Posted February 26, 2009 yes, unless you give us more specific info, like the renderer used, or post in the correct forum you're not going to get very far. Link to comment Share on other sites More sharing options...

Ky Lane Posted February 26, 2009 Share Posted February 26, 2009 Looks like ram/memory problems. 2 things to try: Do the final gather and photon pass at a lower (I do it at half) resolution, save it and lock it. Then use Zaps split render script (http://mentalraytips.blogspot.com/2007/06/doing-big-renders-in-max-9.html) and paste it together in photoshop. Thats how I'd do it.

Ky Lane Posted February 26, 2009 Share Posted February 26, 2009 THis was originally rendered out at 22,000 x 8,000 pixels using Zaps script. Link to comment Share on other sites More sharing options...
luckymutt Posted February 27, 2009 Share Posted February 27, 2009 (edited) An alternate "non-script/non-paste-it-together" method would be to simply render the image by checking off "Net Render" (after starting up Backburner manager and server on your machine, of course (and after you send the job, close your working instance of Max)). In the net render dialog there is an option for "split Scanlines" where you can choose how many parts to break the image into. Each bit is rendered seperately and stitched together for you. The advantage is that the final image does not need to be pieced together seperately in Photoshop, by hand. You do, of course, still need to pre-calc the Final Gather and Photon Map if you are using them. The down side is...well, you gotta gotta start Bburner manager and server, a painful 4 mouse clicks Edited February 27, 2009 by luckymutt Link to comment Share on other sites More sharing options...
