alfienoakes Posted February 11, 2008 Share Posted February 11, 2008 Just a quick question. I am pre-calculating the LC for an animation where I will be using IR and LC as Primary and Secondary. I am calcing the LC with 1st and 2nd bounce set to LC, flythru mode, save file at end. When I do the IR map, could I be calcing that in tandem on another machine.? If so, do I set the 1st bounce to IR and second to none, or do I need a 2nd bounce when pre-calcing the IR map..? I cant remember since the last time I did this as it was a while back....!

But why you dont make it cal in one time. I alway calculate prepass GI by put IR+LC in 1st and 2nd bounce and send thought blackburn to 1 computer, after that send another job using that IR+ LC with Use all server select but Dependencies to previous job. When GI job done, the rendering job will start, noneed to waiting for GI cal. Link to comment Share on other sites More sharing options...
alfienoakes Posted February 12, 2008 Author Share Posted February 12, 2008 Hey Dinh.. So let me just get my head round this; 1. Send 1 job out via BB, to calc the IR AND LC at the same time, on one machine. So every n'th frame and flythru mode etc is ONE calculation, resulting in the IR map and LC map being saved etc.. 2. Send out render job to BB with dependencies on that previous job. Do you need to point the new jobs IR/LC to where the IR and LC map files will be saved, or will it automatically pick them up as a dependency?

Chad Warner Posted February 12, 2008 Share Posted February 12, 2008 You'll need to point VRay to use those saved files before sending the second job (even though they might not exist yet--click on the down arrow in the "file name" box and the last file you saved will show up there) Link to comment Share on other sites More sharing options...
pyang Posted February 12, 2008 Share Posted February 12, 2008 Just a thought, What I found a little better result and faster to me is Cal the LC(wait for it) and then Cal/saved the IR map every nth frame using saved LC as second bounce thru BB to one machine. Set your animation frames dependencies to use that saved IR map in primary bounce only which should include everything you calulated. seems like the frames render quicker with primary bounce only.

Devin Johnston Posted February 12, 2008 Share Posted February 12, 2008 I calc both of them at the same time using BB and 10 render nodes. Link to comment Share on other sites More sharing options...
alfienoakes Posted February 12, 2008 Author Share Posted February 12, 2008 Great.. Cheers guys.. It makes sense to do it that way. Problem I have at the moment, is I am up against it because of certain things going wrong, so I am having to do it the way I can remember.. which is not the slowest, but not the quickest. But.. This is exactly what I wanted to know. I have some more animations coming up, so this is great. Just one more question.. Maxer; You say you calc them on BB using 10 render nodes.. How do you mean exactly, as I thought you had to compute the IRmap and the LCmap on one machine as they couldnt be split..?.. Or do you mean something else...!

Devin Johnston Posted February 12, 2008 Share Posted February 12, 2008 I calculate both IR (animation prepass) & LC (fly-through) at the same time over BB using network rendering on as many machines as I like, but it's usually 10. I've been doing this for a while and I've never had any problems, my animations have no flickering and everything looks great. I'm still using V1.5.0 and I think older versions don't support this method. Link to comment Share on other sites More sharing options...
alfienoakes Posted February 12, 2008 Author Share Posted February 12, 2008 Fantastic.. We have just upgraded to 1.5 here at my main work, but I didnt want to mix and match a project that was started in 1.47... Well this should make things a little easier next time as we have a reasonable network here that I use for all my BB stuff. Cheers... Link to comment Share on other sites More sharing options...
