scripting output path, filename and extention - How?

[ern]

The new "State sets" don't record the file name or path - but I can see that I can use scripting to define it.
does anyone know how to create the script, btw. I hoped the macro-recorder would show me the code, when
I defined the path and filename the usual way, but it don't...

I found a list on Scriptspot with Vray code, but Im not sure how to use it.

something like this?

vr = renderers.current

outPath = "f://temp/"
outFile = "output"
extension = "exr"

vr.output_splitfilename = outPath + outFile + "." + extension

Hi Henning,

I'm not at the office right now, so I can't test.
but if it works, it will solve my batch render problems with vray.

Thanks

Hi Henning
I have testet the script and I get an image I/O error - when it trys to save
tried with exr and jpg

Regards
Erik


vr = renderers.current

outPath = "D:\Priess_plate_plekter\render\final\test\tes t01"
outFile = "test01"
extension = "jpg"

vr.output_splitfilename = outPath + outFile + "." + extension

does the folder actually exist? Is it a spelling mistake in "tes t01"?

[ern]

No it was not a spelling mistake, I got i working with some of the stats sets but not all of them?
It's strange since I used the same code...

What Version of 3dsmax are you using? You've got to beware of escape characters and know how to handle them, also I think you're missing a /. Added an extra line of code to make sure the output path is created too.

Search for "String Literals" in the 3dsmax maxscript help for more info.

vr = renderers.current

outPath = @"D:\Priess_plate_plekter\render\final\test\test01 \"

outFile = "test01"

vr.output_splitfilename = outPath + outFile + "." + extension

vr.output_splitfilename = outPath + outFile + "." + extension

The problem lies somewhere else... 3dsMax Bitmap Object.
When you start up max with an empty scene, assign Vray and run

rend  = renderers.current
rend.output_on = true
rend.output_splitgbuffer = true
rend.output_splitfilename = "e:\\test.exr"

it won't work.

Now open up the render dialog, go to the Split Render Channels - path is in there and everything looks fine, but no file is saved.
Open the file save dialog, and just confirm what's in there already
Render again - bitmap saved!

Reason seems to be, that for whatever reason no max bitmap object has been created for the Vray Framebuffer as long as the file save dialog is not opened and confirmed. Annoying as hell, and pretty dangerous in production if you rely on scripts for the split gbuffers output.
But - here's a hacky workaround:

rend  = renderers.current
rend.output_on = true
rend.output_splitgbuffer = true
mybitmap = bitmap 10 10 color:black filename:"e:\\test.jpg"
save mybitmap
rend.output_splitbitmap =  mybitmap
rend.output_splitfilename = "e:\\test.exr"

What it does is to create a little 10x10 black jpeg to then "convince" vray that there's a bitmap object already. Voilà, saving works without any need to open or edit anything.
Would be glad though if there was another more elegant way to do it, so any help appreciated.

Make sure to edit the pathes according to your needs, that's just rough code not to be meant to be used in production

Best regards,
Michael
