How to get the output image name in Maya?

[yaoyansi]

Hi all,

Is there any simple way to get the output image name in maya? mel, python and MayaAPI  are all acceptable.

For example, in RenderGlobal settings panel, I set "File name prefix" to "<Scene>.<RenderLayer>", and Maya shows the "File name" as "untitled.masterlayer_01.jpg"

I wanna to get the value of File name, that is "untitled.masterlayer_01.jpg".

I have several ways, but I'm wondering is there any better way.

1. text -q -l exampleText1

This command can get the right answer in maya script editor, but it may not work in bath rendering mode.

2. replace the tokens(e.g.<Scene> and<RenderLayer>) with the right values, just like the script in mtoa.

But I have to write many codes for this solution. Is there any simpler way?

Could you give me any clue? Thank you in advance.

Cheers

Hi yys.

I think the MEL command you are looking for is "renderSettings".

MEL Example
//Get the name of the first image in the sequence and process any file name prefix tokens.
string $firstImageName[] = `renderSettings -firstImageName -leaveUnmatchedTokens`;

These can sometimes be renderer-dependent. I believe this depends on whether the renderer overrides the render globals AETemplate (not sure though).

I do it like this:

current_renderer = cmds.getAttr('defaultRenderGlobals.currentRenderer')

if current_renderer == 'vray':
    cmds.setAttr('vraySettings.fileNamePrefix', '<Scene>_<Camera>_<Layer>.', type='string')
elif current_renderer == 'mentalRay':
    cmds.setAttr('defaultRenderGlobals.imageFilePrefix', '<Scene>_<Camera>_<RenderLayer>.', type='string')
elif current_renderer == 'mayaSoftware':
cmds.setAttr('defaultRenderGlobals.imageFilePrefix', '<Scene>_<Camera>_<RenderLayer>.', type='string')

I know that Arnold and RMS18 also uses the standard defaultRenderGlobals.imageFilePrefix.

Cheers,Fredrik
