Rendering Multiple Frame Ranges

V-Ray V-Ray for Maya General

How do you render multiple frame ranges using command line batch renders? Instead of a typical start and end, I want frame ranges like this: 1-10; 15; 29; 37-40

I’m using VRay Tuner to generate a command line file to render from. I then just activate the .command file it generates. Normally this file has flags based on Maya’s syntax generating frame ranges like: -s 1 e-10 . But I want the option to render multiple frames ranges and sometimes single frames to fix a few trouble areas in my renders.

I was reading this help document (Chaos Docs) and the syntax goes like -frames=1-10;15;29;37-40. However, after adding this to my command file the terminal throws an error saying it’s an unrecognized flag. I’m incredibly new to VRay and would greatly appreciate any help in solving this issue. I’m sure it’s a simple one or I’m messing something up. I’ve been searching quite long and hard and am having trouble finding a solution.

Some background info: Using VRay 3.00.01 on OSX.

Try using quotes:-frames="1-10;15;29;37-40"

The semicolon is a special character on Linux/MacOS so the whole thing must be put in quotes.

Hey Vlado,

Thanks for the reply. Gave the quotes a try, but perhaps pasting the whole line will help solve this…I’m doing something wrong:


/Applications/Autodesk/maya2015/Maya.app/Contents/MacOS/Render -r vray -frames=“1555-1557;1601;1670” -im "loan_shot_005a" -preRender "setAttr vraySettings.imap_currentPreset 4" -preRender "setAttr vraySettings.dmcMinSubdivs 1" -preRender "setAttr vraySettings.dmcMaxSubdivs 8" -preRender "setAttr vraySettings.dmcThreshold 0.01" -preRender "setAttr vraySettings.dmcs_adaptiveAmount 0.85" -preRender "setAttr vraySettings.dmcs_adaptiveThreshold 0.01" -threads 12 -x 1920 -y 1080 -proj "/Volumes/Groot/Projects/xxxx" "/Volumes/Groot/Projects/xxxx/yyyyy/zzzzz.ma"
open "/Volumes/Groot/Projects/xxxxx/yyyyyy"
growlnotify -n Maya Render -I /Applications/Autodesk/maya2015/Maya.app -m Maya Render Done!

And receive:


Invalid flag: -frames=“1555-1557

I think I get the process now. I need to export a .vrscene to be able to use the standalone commands as I was calling Maya’s flags instead with my script mentioned. I think I got it from here, but will need to figure out the proper way to export a .vrscene now :slight_smile:

Oh, you are using the Maya “render” command. Then it won’t work I’m afraid - it only supports start, end and frame step; this is something that Maya handles, not V-Ray. The -frames command is for V-Ray Standalone.
