automating a render

[todd....@gmail.com]

I need to setup a script..and having a hell of time finding resources online to show the commands or even a solid "stable" approach to this

so I have a script setup to alter a few things in my scene, set a new frame and what I need is pointers on then having it render the image to disk using Arnold to a set path

that last bit is where I am having issues finding anything on the commands or proper way to do it

are you rendering with standalone arnold kick.exe? If yes, here's part of code ripped from my setup to export .ass files:

import maya.app.renderSetup.model.renderSetup as renderSetup

def RenderCacheExport(renderLayers, frameList):

    tryAttr("defaultRenderGlobals.animation", 1) #tryAttr is a wrapper around setAttr

    tryAttr("defaultRenderGlobals.extensionPadding", 4)

    tryAttr("defaultArnoldDriver.halfPrecision", 1)

    tryAttr("defaultArnoldDriver.tiled", 1)

    tryAttr("defaultArnoldRenderOptions.bucketScanning", 0)

    tryAttr("defaultArnoldRenderOptions.enableProgressiveRender", 0)

    for f in frameList:

        mc.currentTime(f, e=1)

        for rl in renderLayers:

            render_setup = renderSetup.instance()

            renderLayerList = render_setup.getRenderLayers()

            renderLayerList = [l for l in renderLayerList if l.name() == rl]

            render_setup.switchToLayer(renderLayerList[0])

           

            mc.setAttr('defaultRenderGlobals.imageFilePrefix', f'c:/temp/out_{rl}_{f}.exr', type='string')

            mc.arnoldExportAss(cam='|persp', f=f'c:/temp/out_{rl}_{f}.ass')
