Batch Render with V-ray In Maya

[Anonymous]

Hello. I have problem Batch Rendering with Windows 10, vray 3.52 in Maya 2017 Update 3.

When i hit the batch render button Its says "render completed" but nothing saved.

I Enabled "Animation" in common tab and set the frames but nothing saved.

Anyone know how to help?

Thank you

Hi,

It could be a number of problems.  From my experience, it could be licensing issues or read/write permissions to your render output folder.

My first suggestion would be to try rendering through the V-Ray frame buffer by unchecking "Render animation only in batch mode".  If that works, then your license is working correctly.

Are you using any render layers?  If so, make sure the layer/s are set to render as below:

If none of these help, I wouldn't mind looking at your scene file, if you don't mind sharing.

Kind regards,

Ed

Thank you @RooftopAnimation.My problem was locally from my Windows which I fixed it.

Can I ask what do you suggest for Rendering a heavy scene animation with Vray?(U seems like have a lot of experience) Is it :

1.Irradiance map + light cache

2.Irradiance map (prepass mode) + light cache

3.Irradiance map + Brute force

4.Irradiance map  (prepass mode) + Brute force

5. None of above.

Prepass mode export a lot of map file which take time and they are not that great.What's your suggestion?

Thank you.

Hi,

Sorry for the delayed replied. Been working 2 jobs this week 😕

If there are any moving objects, doing the prepass won't work out well.
Prepasses are for static scenes and you basically build your irradiance map
by flying through your scene. I haven't done that in a while, but there
should be quite a few tutorials online.

If you want a scene with no flickering, go with brute force + brute force,
but it will take ages to render. I usually go with 1. Irradiance map +
light cache.

I pretty much use default settings. You can see my typical setup below.

V-Ray can be quite complex, and you can tweak it so finely, but hopefully
this gets you in the right direction.

Well thank you @RooftopAnimation and I understand for delay...

I looked at website you mentioned and it's really helpful... merci. I used prepass because chaos group suggested that for animation.

by the way your images don't show up. 

have a nice day.

i'm not able to batch render using Vray 
my vray plugin is licensed properly..

[RooftopAnimation]

Hi there,

Could you please post the error you are getting?  The error should be output to the script editor.

You can also ask ChaosGroup's support for help - they are very good:  [email protected] 

Kind regards,

Ed

bro I am using the student version... and I am getting this message.. I cant batch render through VRAY in maya 2017

[RooftopAnimation]

Hi,

I think it's either a limitation of the Maya student version or the way V-Ray interacts with the student version.  Further Googling required. You should still be able to render a sequence through the V-Ray buffer still.

Just make sure to unceck "Render animation only in batch mode" in the "Animation" section as seen here:

Kind regards,

Ed

My rig wont batch render any of my scenes with vray(chaos Group Plug in) but if i were to render out any of my scenes anywhere else it will work. i keep getting this in the command line :

(// Result: Rendering with V-Ray... //
// Result: Rendering Completed. See mayaRenderLog.txt for information. //) 

Ive uninstalled and reinstalled everything but nothing is working. It used to to batch render with no problem but now i dont know what to do.

Hi, I haven't used Maya in over a year and V-Ray even longer than that, but I could take a quick look.

Can you please post the mayaRenderLog.txt?

sorry I'm just getting off work. But here it is.

[RooftopAnimation]

Hi,

I'm looking for the actual file, you can find it here per OS.

• [Windows] %USERPROFILE%\Documents\maya\mayaRenderLog.txt
• [OSX] ~/Library/Logs/Maya/mayaRender.log
• [Linux] ~/maya/mayaRenderLog.txt

Yes sorry here it is

[RooftopAnimation]

Thanks for the file.  Found the issue and unfortunately it's a limitation of the V-Ray PLE 😔

Error: V-Ray batch rendering is disabled in PLE.

Dang ok so i got to buy the product, thank you so much i appreciate it.

[RooftopAnimation]

If it's just for learning or personal work, just render in the viewport. You must just uncheck something like Render animation in batch only (I don't recall exactly and don't have an active Maya license so can't look)

It will take a bit longer than batch rendering and if you want to control CPU usage, in Windows you can go to the Task Manager> Details tab> right-click on Maya.exe or whatever is using your CPU at render time and set affinity> uncheck CPUs you don't want to use.

There may be an option to disable the V-Ray Frame Buffer, in which case it may help speed up the rendering process a bit.
