    I have render settings overrides set for many render layers, including overrides on a per-layer basis for Start Frame, End Frame and Start Number. This allows me to render only a short frame range for each of the items that appear in the scene for only part of the animation, rather than rendering 2000 frames of blank images for every layer. However, the entire Muster frame range is getting rendered for each layer, now matter how I set this up or what template I try to use (MR, Maya SW, or Maya Layer).
    Any workarounds?
    Thanks,
    Sean

    P.S. – I have extensively tested the Render Layer overrides functionality using Maya Batch Render, and it works great. Can’t figure out why Muster jobs render every in the specified frame range every time, ignoring the overrides. Is there a render flag I can set that will tell maya to respect the layer overrides?

    since i am currently working on the same problem:

    the problem is the following:
    if you create these layer overrides in maya and batch render it. mayas renderer checks what is written in the render globals and which overrides are set..
    this works like expected:
    render myscene.mb

    but as soon as you would try to do the following:
    render -s 1 -e 10 myscene.mb
    all your render layers will render from frame 1 to 10 because you override (!) the values set in the render globals – no matter in which layer or if they already had layer overrides on them.

    the problem: muster has to do exactly that external override to be able to render the images on a renderfam.

    since i noticed that problem quite some time ago, i am currently writing some MEL to be able to submit a single scene several times to muster, and have it only render the desired frame ranges.

    to be honest: i am not using the muster connector tool at all. so i have no idea what it is capable of. i am using a self written MEL code to submit all our jobs to muster.
    maybe if you ask nicely leo can implement that functionality some day :)

    but for you as a workaround:
    save your scene once with all correct settings in it. only make the layers renderable, that have the full frame range. submit that one to muster.

    for the missing render layers that have different frame ranges you can now add another submission to muster which has additional parameters:
    -rl renderLayer1,renderLayer2,…,renderLayern
    like that you make sure only these render layers are rendered abd you can enter their respective frame range in muster.. all from one single scene file.

    cheers
