Kelley Posted February 16, 2008 Posted February 16, 2008 To speed up render times [in a multi-frame animation] am I right in assuming that objects that are turned off in the Properties no longer exist are far as render times and computing effort? I have a situation in which I've built jungle foilage. The individual 'leaf units' are light in CP's, but there's a lot of units. I'm thinking it would be nice if I could have them turned off before they enter the frame, and turned off again after they leave. Quote
KenH Posted February 16, 2008 Posted February 16, 2008 They don't render. Whether they don't effect render time needs exploring. Though their very existance is taking up computer resources. Quote
3DArtZ Posted February 16, 2008 Posted February 16, 2008 In my own experience and as far as I know it does speed up rendering. If its not active, its not there. Quote
Kelley Posted February 16, 2008 Author Posted February 16, 2008 In my own experience and as far as I know it does speed up rendering. If its not active, its not there. That's encouraging. I'll put it to the test. Thanks. Quote
NancyGormezano Posted February 16, 2008 Posted February 16, 2008 I'm thinking it would be nice if I could have them turned off before they enter the frame, and turned off again after they leave. If the model is out of the field of view I'm guessing it won't matter (significantly) in the render times, as I believe there is some quick preliminary culling (visibility testing) that is done before computing the frame's imagery. I would guess this based on the fact that frame computation times change based on what's in view. But if models are Active it will affect the real-time response. Rather than animate the Active status - you will probably want to change the real-time draw mode to not visible (red line thru circle) for the model. (I haven't actually tested the first statement) Quote
Kelley Posted February 17, 2008 Author Posted February 17, 2008 OK. The returns are in. The envelope, please. If objects are turned off, the CPU apparently doesn't see them and does not have to hold their CP positions in its thoughts. In the first anim., "Bare Bones and Red Lantern" the rocks and trees are turned off. It took 59 minutes to render the 10 secs. In the second, "All the Foliage", it took an hour and 43 min. Almost twice the time. It is true, the foliage isn't very visible, even for being a night scene, but I intend to punch up the specularity so the leaves highlight mo' betta'. The object ahead of the engine is a handcar [being chased] and here's the little guy who will be driving it. The two animations are rendered from different cameras.

KenH Posted February 17, 2008 Posted February 17, 2008 Kel has animation to show....finally? This I have to see. Edit: Looks good! One wheel trains....very original. Quote
Kelley Posted February 17, 2008 Author Posted February 17, 2008 Kel has animation to show....finally? This I have to see. Could it be your turn soon? Quote
KenH Posted February 17, 2008 Posted February 17, 2008 Could it be your turn soon? I'll refer you to TWO for all my most recent animation work. Quote
