Maya for 3D Printing - Rapid Prototyping
In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

Hi Rodrigo, When exactly does Maya crash?

Thanks for the quick response by the way.

Hmmm... Could you try disabling the V-Ray frame buffer and then trying it again? What OS are you running Maya on?

I've just ended a support chat with Chaos Group. Apparently there is a bug in first Vray 3.0 version. As soon as I can, I'll test your code to see if it is fixed with what they did. Thank you very much

Start frame is the first frame to render, and end frame is the last frame to render. The script will render all values in-between. Make sure that you keep the semicolon ; as MEL requires this. Also be sure to execute this script in the MEL lab of the script editor, and not the python tab.

Let me know if you're still stuck.

Hi NextDesign,

Thank you so much for your awesome script!! However, it seems I can't get it to work correctly with Renderman and "it" render viewer. It does render the image, but much smaller resolution than the actual resolution in the render settings. Even, when I increase the size, still it doesn't change. Also, it doesn't save the renders. I would appreciate if you could help.

Thanks

Hi John,
Been using this script for a few years now but I keep running into memory problems. When I render a scene with hundreds and hundreds of frames, maya crashes because of memory problems. My server has 68GB of RAM, so I was wondering whether or not anyone else is having this problem?

Wow, it seems this script has attracted quite a bit of attention

Here is a fixed version that will allow rendering in multiple renderers, as well as work in Maya 2011!

Code:
// Batch rendering workaround - John Mather (NextDesign)
string $filename = "render";
string $cameraName = "persp";

int $startFrame = 1;
int $endFrame = 3;

string $directory = (`workspace -q -rd` + "images/");

for ($i = $startFrame; $i <= $endFrame; $i++)
{
    currentTime $i;

    // Old version
    // render -x `getAttr defaultResolution.width` -y `getAttr defaultResolution.height` $cameraName;
    
    // New version - supports MR and other renderers!    
    renderWindowRender redoPreviousRender renderView;
    
    string $concatFilename = $directory + $filename + "." + $i;

    if (`getApplicationVersionAsFloat` >= 2011)
        // Thanks to nowayfra on creativecrash for his workaround
        catch(eval(renderWindowSaveImageCallback ("renderView", $concatFilename, `getAttr defaultRenderGlobals.imageFormat`)));
    else
        renderWindowSaveImageCallback ("renderView", $concatFilename, `getAttr defaultRenderGlobals.imageFormat`);

    print ("Saved " + $concatFilename + "\n");
}

print ("Completed rendering of " + ($endFrame - $startFrame) + " frames.\n");
P.s. Many thanks goes out to nowayfra on CreativeCrash for his Maya 2011 fix! (http://www.creativecrash.com/forums/...on_post_306312)

Edit: Fixed a small bug that would stop all frames from being rendered.

Help...

Hi guys,

I have the same problem too, I have attached the two image below. The thing is, I am new in MEL coding so I have no clue how, or where to paste this code in the program. Can someone send me a description or video tutorial on this, so I can finish my render?

Got it :D

I have done it, and it works wery well. Altrough, I am not able to select my cameras, it only wants to render the persp. camera. In the newer versions, I can not see the camera selecting line in the script. Can you tell me the way to select different cameras?

one million thanks - and a question

hi john,

not sure if you'll get this but also wanted to sign up to say thank you very very much and to ask you a question about your amazing script.

does it handle sub frames per chance? i have a scene time warp in my scene and when it hits those frames where it kicks in, the render just ceases. it has worked brilliantly up to those frames though. wondered if there were a bit of code to add that might get me over this hurdle. i noticed the timeline went to frame 670.2 and the frame never finished rendering.

so angry i never got interested in coding.

cheers!

super happy dude.
