V-Ray standalone, stuck on Building Static Hair

[Karol.Osinski]

Hi all, I am trying to render one Maya scene after another using V-Ray standalone and method with .bat file suggested by waaazoo in my old post https://forums.chaosgroup.com/forum/...-after-another.
After long time of not using it I gave it a try again and successfully rendered 2 test scenes with a simple cube, although our everyday production scene got stuck on "Building Static Hair". It renders without problems from Maya with both CPU and GPU engines. Any ideas what might went wrong inside the V-Ray Standalone?

Did you try to render the same scene by exporting a Vrscene and rendering batch with the Standalone (so without using Maya batch)?

I was planning to give it a try, will let know how it goes thanks

waaazoo Hey mate, sorry for bothering you. I still haven't got a chance to try to .vrscene method... In a meantime did few tests with the Maya batch you showed me but it does not recognize the animation.
I think it always renders the first frame and that's it. I could not find any Autodesk documentation explaining what are all these parameters, I wondered that there must be probably one to specify number of frames to be rendered.

"C:\Program Files\Autodesk\Maya2020\bin\render.exe" -r vray -proj YOUR_PROJECT_PATH -cam camera1 -s 1 -e 1 -b 1 -x 5000 -y 3300 -im IMAGE_OUTPUT_NAME SCENE_PATH_NAME.mb

-s = start frame
-e = end frame
-b = by frame
-x = horizontal resolution in pixels
-y = vertical resolution in pixels

so, id you want to render an animation from frame 1 to 500, every 5 frames, in HD 1080p you have to write:

"C:\Program Files\Autodesk\Maya2020\bin\render.exe" -r vray -proj YOUR_PROJECT_PATH -cam camera1 -s 1 -e 500 -b 5 -x 1920 -y 1080 -im IMAGE_OUTPUT_NAME SCENE_PATH_NAME.mb
