Calling Render Presets Via Batch Script

[toast--2]

Hi all,

Just wondering how to call up a render preset when scripting a batch file. I've tried numerous options that don't work and I can't find anything about it in the docs.

Current batch file script:

QUOTE
render -r mr view1v05.mb
render -r mr view2v2.mb
render -r mr view3v2.mb
render -r mr view4.mb
render -r mr view5.mb
render -r mr view6.mb
render -r mr view7.mb
render -r mr view8.mb

As you can see 8 scenes, so it's hard to keep render settings consistent across all 8 scenes. If there was a global default I could load it would work quite well.

The preset I've saved in Maya's GUI is "architecturalHQ_2"

Thanks.

hy,

why don't you set the rendersetting before saving your scenes?
other than that, also i haven't tried myself you could use the "-prerender " flag and type in the code for setting the preset.

Thanks for replying pete.

It is possible to save the render setting before, but I'd like a "global setting" to continually fall back on. I'd also like to do this because so I'd be able to open a scene change it to low quality (so I can change shaders or whatever) then exit and save without worrying about putting the render settingsback.

It sounds lazy but I have a lot of shots that need organizing all the time and this would be a nice time saver.

I've also tried the "-prerender " but it doesn't quite seem to load the preset. It always says exits the render with 201 status because it can't fine the preset. I'm quite hopeless at mel, obviously.

sure just call the changes in prerender scripts, figuring out how to do it isnt really rocket science since you can chaneg it in the gui and let maya echo what it does.

I've tried that. Maybe I'm missing something obvious, but the command isn't working for me:

loadNodePresets "presetname";

"// Error: Cannot find procedure "loadNodePresets"."

Batch mode does not load a gui, so not all functions are defined the way they are defined in the GUI mode. What you do in gui mode is ask what the hell is loadNodePresets , with following:

whatIs loadNodePresets;

maya then tells you where the function is defined, you then either source the file in question first. OR read the file and replicate just the relevant parts of it with sytem commands.

No other (ok so 3 commands arent documented, and 4 others not fully) mel commands exist except the ones in the command reference rest is stuff thats been loaded later So you shoudl allways be reading the mel scripts you indirectly use.

Aha! Your knowledge of Maya is very deep, thanks a lot for helping out.

It seems the loadNodePresets command only works after I manually load a Render preset via the Render Settings. After I do that I can use whatIs loadNodePresets;. This makes sense because of what you just said.

However looking through the unifiedRenderGlobalsWindow.mel - it's quite...big. But I'll try and see if I can see what's what and how the presets are loaded. Thanks again.

don't know if that's easier, but you could also take the commands from the script history, echoed when you change a rendersetting. so if you change the samplesettings to 0 and 2 maya will echo what the mel command for that is.
(renderglobals.sample blabla, don't know by heart). that would be like making your own preset. take that and type in that renderflag.
hope that helps(and works!)
