Get output image name with python

[pechart]

Hi!

Is there a way to get the resolved image name from the vraySettings with python? From Maya Software you can get it with

name = renderSettings(firstImageName = True, fullPath = True)

for example.

Thanks!

Yep, something like this:

from vray.utils import *

p=findByType('SettingsOutput')

dir=p[0].get('img_dir')
fname=p[0].get('img_file')

print dir+fname

Very interesting, thanks !

In my test, I get this result in the logs :
O:/TEMP/TEST/images/testVray/masterLayer/testLay.tiff
O:/TEMP/TEST/images/testVray/layer1/testLay.tiff
O:/TEMP/TEST/images/testVray/layer2/testLay.tiff

So, it is executed once for each render layer.
Note that it's not executed once for each frame, which explains why I get testLay.tiff instead of testLay.0023.tiff

[vlado]

Yes, the Python script is currently run only once before rendering a layer begins. We might have to add a separate callback between frames.

Looks good, thank you! Ist vray.utils documented somewhere?

[vlado]

There is the documentation concerning the python part here: http://www.spot3d.com/vray/help/maya...ene_access.htm

For information about all the different types of plugins and their parameters, you can look at .vrscene files exported from V-Ray for Maya, and you can also use the plgparams tool from the SDK.

I get a Fatal Error when I do this in Maya2012 HF2 with vray 2.10.01 when the funtion gets called. Any ideas?

EDIT: With Maya2011 SP1 and the Vray 2.00.04 Release I also get a Fatal Error.

I'm on windows7, btw.

There is a problem in the recent nightly builds; should be fixed for the build tomorrow.

I just checked the latest nightly build. But I still get the Fatal Error.

[vlado]

Yes, sorry didn't get there yesterday (we had to move to a new office); I will let you know the revision number when it's fixed, hopefully a bit later today.

Hm, on my machine the crash was caused by a wrong copy of vrayformaya.mll being loaded by the python module. The crash went away after I removed the duplicate version.

[pechart]

Hm, okay. What was the problem last time?

[vlado]

It's been the same problem for me; can you get me the crash dump from Maya? (It's in the %temp% folder, MayaCrashLog*.dmp)

Best regards,
