New to MEL: updating a scene for a render without loading maya.

Anonymous — Thu, 13 Aug 2009 19:10:01 GMT

Hello,

At the end of the day I'd like to be able to position my camera in various positions while rendering the scene.

Speed is also a factor so I'm very interested to know of MEL scripts can be executed without having to load up Maya. I know the Maya batch renderer can render scenes without opening the application (./Render -cam persp file), can the same be done with MEL?

I also cannot animate the scene since the positions of the camera will be user specified while the script is running.

Here's what I have so far for my MEL script:

//I Load up my scene and update the "persp" camera position, save, and quit.

file -import -type "OBJ" -ra true -namespace "test" -pr -loadReferenceDepth "all" "modelname";
setAttr "persp.translateX" 10;
setAttr "persp.translateY" 10;
setAttr "persp.translateZ" 10;
file -rename "supercool_filename";
file -f -save -options "v=0" -type "mayaAscii";
quit -a;

In a console:
I run the script:
./maya -script myScript

I render the scene:
./Render -cam persp -im uniqueRender -of png supercool_filename.ma

Right now, I have to wait about 13 seconds for the MEL script to run and about 7 seconds for the Render to take place. The scene only has 18 triangles so I was hoping to get faster times.

Thus, is there way I can shave off a few seconds by not wasting time opening maya just to update the camera position?

Thanks for your patience for a MEL nub.

Perhaps you could use the -preRender flag for commandline render, something like
render -preRender "source myScript" -cam persp -im uniqueRender -of png supercool_filename.ma
