Setting Render Settings

[Tim Crowson]

Hey folks,

I did a quick search through this group's threads and couldn't really find the answers I was looking for...

I am still quite a novice with how Maya does things. I touched the tip of the iceberg a few months ago but got pulled onto other things. I'm struggling with how to set render settings in Maya. Specifically, I'm wanting to set things like render resolution, aspect ratio, image format, render cam.

On a related note, I'm also curious about how to set render paths properly. In Softimage there is a root path field in the scene settings, but Maya seems to want to me to set this in the Project Settings. Any insight here?

Thanks for your help! Someday I won't be a Maya noob anymore, I promise.

welcome to maya world ;)

if you do a listAttr on renderglobals you will see all the attrs which connected to renderglobals eg :

cmds.listAttr("defaultRenderGlobals")

# Result: [u'message', u'caching', u'isHistoricallyInteresting', u'nodeState', u'binMembership', u'macCodec', u'macDepth', u'macQual', u'comFrrt', u'renderAll', u'ignoreFilmGate', u'quality', u'resolution', u'clipFinalShadedColor', u'enableDepthMaps', u'enableDefaultLight', u'currentRenderer',etc .....] #  list was long so i just removed bunch of items

then you can say 

cmds.setAttr("defaultRenderGlobals.imageFormat", 8) #this will set jpg as image format.

Hope this help

Thanks. I've used this for certain attributes, but I can't figure out resolution specifically. 

For example, cmds.getAttr("defaultRenderGlobals.resolution") throws an error: "Error: Message attributes have no data values." Hence some confusion....

Have a look at what you get in the Attribute Editor when you select the “defaultRenderGlobals” node. It’ll give you some hints as to what is going on. By the looks of it, resolution is hooked up to “defaultResolution” which is another node. You can change the attributes from there.

If you aren’t familiar with selecting nodes by name,

1. try the little box to the top of the GUI, it’ll have a little fly-out menu to allow you to “Select by name”.
2. Otherwise, they will all be available via the Outliner and can be filtered from there too, if you untick “Show DAG Objects only”,
3. and thirdly there is cmds.select('defaultRenderGlobals').

Hope it helps!

Okay defaultRenderGlobals, defaultRenderQuality and defaultResolution those are separate nodes in maya, if you want to get rez then 

cmds.getAttr("defaultResolution.width")

cmds.getAttr("defaultResolution.height")

As Marcus  said you can select each of them and see what attrs there :)

Thanks, I figured those attrs were on a different node, but I didn't know what node to look at.

For setting framerate, am I right in thinking I need to target yet another node, some preference node? I can work with attributes, as long as I know which node I need. I just don't know what nodes are out there and which ones have the attributes I want...

Thanks for your help!

Oh, and I figured I would take a look at the Node and Attribute Reference section in the docs, but that doesn't list even the nodes you've pointed me to here. defaultRenderGlobals and defaultResolution aren't even listed there. Is there a place where I can get a more accurate list of nodes? (on 2016 SP1 here)

[Marcus Ottosson]

That’s right, you can look them up in the Node documentation, but what you searched for was not the node type, it was their name. Their type is listed to the left of it’s name in the Attribute Editor.

This node is of type: resolution.
