command line render flags and render layer

[ignuf]

hi,
ok I'd like to do a simple batch render using terminal and .bat file which works fine using the string below :-

render -r vray -x 1280 -y 720 -s 1 -e 442 -verb "S:/projects_current_Drv/my_Project/scenes/shed_11.mb"

I would however like to render a particular render layers so looking at Maya help pages there's a render flag for render layers :

-rl <boolean:name>

so i've tried a variety of versions to get this to work but so far no joy can anyone advise please ?

so far tried:

render -r vray -x 1280 -y 720 -rl true:ground_RL -s 1 -e 442 -verb "S:/projects_current_Drv/my_Project/scenes/shed_11.mb"
render -r vray -x 1280 -y 720 -rl True:ground_RL -s 1 -e 442 -verb "S:/projects_current_Drv/my_Project/scenes/shed_11.mb"
render -r vray -x 1280 -y 720 -rl 1:ground_RL -s 1 -e 442 -verb "S:/projects_current_Drv/my_Project_/scenes/shed_11.mb"
render -r vray -x 1280 -y 720 -rl yes:ground_RL -s 1 -e 442 -verb "S:/projects_current_Drv/my_Project/scenes/shed_11.mb"

Are you sure the separator is ":" and not "|"? On linux the help of the Render executable states that the separator should be "|".

hi,
thanks for the suggestion , gave it a go and it seemed to start working but then said completed render almost immediately( the render typically takes 6 mins to render a frame ) with a message ending in "maya exited with status 0" , double checked the name of the render layer and its correct in the string "ground_RL"

just get the feeling that the -rl is redundant or something ...

Can you check what the mayaRenderLog.txt says. It's usually in the default user's documents > maya folder.

[ignuf]

hi Alex,
it seems to be listing the last successful render i made on the same project, nothing in there about the attempted render using the -rl flag

kind regards
Guy

Can you delete the log file and render again - Maya will create a new one.
In case you can share the scene - please do, we could take a look and see what's wrong.
It would also help to know you Maya, VRay and OS versions.

hi Alex,
i've created a test scene with a load of cubes in it with a std vrMaterial applied and a dome light. there's two render layers, one called "test_useThis_RL" and another called "test_dontUse_RL"

I did a test render inside of maya to make sure the scene rendered , which went through no probs,

ive got a .bat file called batchRender_test_RL.bat which i created in notepad (win10)

the string in side the .bat file is below , i used a pipe symbol copied from online "¦" and one using the keyboard "|",

//--------------- test------------

render -r vray -x 1280 -y 720 -rl true¦test_useThis_RL -s 20 -e 30 -verb "S:/projects_current_trboDrv/Old_shed_Project_trboDrv/scenes/test_rlRender_001.mb"

render -r vray -x 1280 -y 720 -rl true|test_useThis_RL -s 20 -e 30 -verb "S:/projects_current_trboDrv/Old_shed_Project_trboDrv/scenes/test_rlRender_001.mb"



i re-named the maya render log and tried to render using the . bat file but no new render log was created. but ive copied the output from the terminal :-

That's a bit odd, to say the least. Can you send us the scene - the test one with cubes you made for the last example?
Also, can you try rendering through a command prompt by inputting directly the command-line? Maube try skipping the -verb flag (not that it has anything to , but who knows).

[ignuf]

hi Alex,
tried just entering the string into a terminal it started but then said completed almost straight away .

how/where do i upload the scene file ?

regards
ignuf

[yolov]

If it's less than 10MB you can upload it directly here. Another option would be to upload it on a shareable place like dropbox, google drive or similar and then send us a link. A third option is to provide you with ftp access to upload it directly to us.

[ignuf]

hi Alex, sorry for the delay getting back !
please see attached link to google drive
