View Full Version : Rendertime per feature list ???

I was just reviving an old character of mine and was completely blasted by the rendering times it takes.

Is there a list on how long the features take per se ? How expensive is Motion Blur in relation to DIsplacement Maps ? How do Area Lights factor in ?

Is there any way to get a breakdown in the rendering log other than to render each feature seperately and then do the math ?


Also, feel free to hint me on how to get a slicker look on that freak. I wanted to use displacements to get the different layers (muscles, skin, bones) to interwind. And the hair to add some comic "Frighteners" touch to it. And Motion Blur for an object thatīs to test his skills. Perhaps even some great lighting stuff like FG to get some nice color bleeding effects. But at 2 hours per frame I canīt even afford the current look I donīt really like....

In the Render Options, turn on Progress Report. Then, before rendering, open the Script Editor, and make the History Log to use all the space of the Script Editor. When you render, a progress of the rendering will be displayed in real time.


Hope this helps

Hmmmm. No other way that differentiates between features ? Or at least a way to insert timers into the log ? Iīd hate to sit besides the computer for 2 hours and write down the corresponding times to the log-lines...would look rather...weird ? Low-tech ? Absurd ? :rolleyes:

"Progress Report" is okay, though, at that speed it is just to reassure myself the machine has not crashed...

"Verbose" puts out heaps of data I have yet to dig through, but, as I mentioned, without any timing hint itīs more of a pain to derive processing-time for individual effects...

Iīve seen some kind of network-render-manager thingie once. Would an additional tool like that yield some of the info I seek ?

if you render from a command line (thing that you should do anyway) you can parse the resulting log into a file and eventually find someway to timestamp that while it's generated.

the weirdest way i'v seen of doing this was a friend 2>ing the line into a mirc client (since mirc timestamps by default).
It didn't slow down the rendering much (almost not at all) and it actully worked.

check out some DOS sites to learn how and where to output command lines (2> for error output (MRay verbose is generated like an error output, > for logs output and so on and on and on...)
