Maya-使用Python渲染序列

Question

I am making a test render script in Python and am having problems getting my render calls to output sequences, and not just one frame.

I am working in Maya 2015 on a Windows 7 machine.

I have tried using the ogsRender() (Hardware 2.0) and render() (Software Render) commands. And while both of them proclaim to be able to output sequences in the docs, I can't seem to get them to do so.

import maya.cmds as cmds
cmds.render()
cmds.ogsRender()

Being a test render script, it doesn't need to be pretty--just fast.

hwRender() (old Hardware Render) seems to work fine, outputting frames according to render settings. However, I get a lot of white artifacts from any intersections when using that render, making it hard to see if things are correct.

Does anyone know how to get render() or ogsRender() to output sequences?

Or maybe remove the white artifacts hwRender() produces?

Thanks for your time!

Just incase this is what you're after, here's a rough approach you could use where you jog the frame and make your own batch-ish render system.

The only reason I've used renderfn rather than hardcoding maya.cmds.render is just incase you wanted to hook into something else (like, I dunno, dropping out some kind of scenefile that you'd feed into a renderfarm or suchlike)

import maya.cmds as mc
def render_seq(startframe = 1, endframe = 10, renderfn = mc.render, renderfn_args = None):
    '''render out a sequence of frames as per global settings

    defaults to using maya.cmds.render for frames 1-10'''

    # save state
    now = mc.currentTime(q=True)

    for x in xrange(startframe, endframe):
        mc.currentTime(x)
        renderfn(renderfn_args)

    # restore state
    mc.currentTime(now)
