Hi,
I'm running a pseudo render farm in our university and we are looking at launching renders through cmd as Backburner is everything but useful to render with.
I cannot seem to find any documentation on how to enable half precision when rendering through command line. Help doesn't show any flags or anything. I don't know if I could set the defaultArnoldDriver.halfPrecision=1 as a system variable or something to make it work.
Thanks ๐
You can use a pre-render script
Hey @Stephen Blair
Thanks for the quick reply, I've created a .mel file with several more arguments to keep the render homogeneity but I don't know how to run them, as the flag I've seen only accepts an argument right on the code instead of a path to a .mel file. I have all this arguments at the moment:
setAttr "defaultArnoldDriver.halfPrecision" 1; setAttr "defaultArnoldRenderOptions.motion_blur_enable" 1; setAttr "defaultArnoldRenderOptions.mb_object_deform_enable" 1; setAttr "defaultArnoldRenderOptions.mb_camera_enable" 1; setAttr "defaultArnoldRenderOptions.motion_steps" 6; setAttr "defaultArnoldRenderOptions.ignoreMotionBlur" 1; setAttr "defaultArnoldDriver.exrTiled" 1; setAttr "defaultArnoldDriver.autocrop" 1; setAttr "defaultArnoldDriver.mergeAOVs" 1; setAttr "defaultArnoldDriver.exrCompression" 2; setAttr "defaultRenderGlobals.extensionPadding" 4;
I've ran across this plugin but I wonder if there was a way to pass them all without using external plugins as this project will have to render on a legit Qube managed render farm in the future and we don't want to bother them with random plugins.

Also here is our batch file just in case there's something wrong about it:
SET MAYA_RENDER_SETUP_INCLUDE_ALL_LIGHTS = 0 set FILEPATH=X:\rdr\lgh\render_lgh0010\scenes\render_lgh0010_v1.ma set PROJPATH=X:\rdr\lgh\render_lgh0010\ set RDPATH=X:\rdr\lgh\render_lgh0010\images set FRSTART=96 set FREND=270 set CAMNM=lgh_0010 set RESOL=-x 2048 -y 858 set PRSCRIPT=X:\mtoasettings.mel "C:\Program Files\Autodesk\Maya2018\bin\Render.exe" -r arnold -proj %PROJPATH% -rd %RDPATH% -s %FRSTART% -e %FREND% -cam %CAMNM% %RESOL% -rl 1 -ai:lve 2 -ai:alf 1 -preRender %PRSCRIPT% %FILEPATH%
Thanks
