Save to Root

[glorybound]

Is there a way to set up V-Ray to save my layered EXR's in the root of the MAX file? I have a hundred kitchens that I have been manually saving through the VFB, but I want to automatically save those where the MAX file is.

The obvious answer is to use V-Ray raw image file setting in the V-Ray tab, Frame Buffer. Then just make sure you use EXR extension instead of vrimg, and set the path to where your max file is saved.

OR

If you're using max project folders, then set your "RenderOutput - .\renderoutput" path the same as your "Scenes - .\scenes" Path. Then you can just click the save button in the VFB and default path will be same as your scene file.


I don't think you would ask if the answer is that obvious so I'm geussing there's more to the question...

If you have multiple different kitchen files, each with different cameras, etc, are they in the same folder or seperate folder? Its pretty simple to script a button that will output to whereever you want, naming the file whatever you want, and it could be based on camera name, scene name etc.

Need more info to give you a more appropriate answer.

I wanted my EXRs to be automatically saved where my MAX file is, regardless of where it is. Normally I work in my MAX file structure, but with these 100s of kitchens, I am not.

give me an example of a max filename, and the output filename you expect....
only 1 cam per max file?

Maybe this will help understand

Here is a script that will do that for you.
You will find it under Mr.Max category so you can create a shortcut /button for it
this script will do the following :
1-enable vray image raw file saving
2-add the address like the following: "max file path + max file name + .exr "
now when you render, VRay will automatically save the render to the same file location with the same file name.
you will need to run the script shortcut /button once for every file of course.
let me know if you need any further help with it .

it seems that there is an issue with attachment in the forums. so here is the script code:

macroScript Autosetpath
category:"Mr.Max"
toolTip:"Auto set path "
(
vr = renderers.current
vr.output_saveRawFile = true
vr.output_on = true
vr.output_rawFileName = maxfilepath AS string + MaxfileName as string +".exr"
)

Awesome, thank you! I will give it a try.

That worked, however, I am looking for each separate element. I am using Post-Manager, so it'll create all my blending modes and groups from the individual files.

[M.Max]

Aha, so Post-Manager doesn't support multichannel exr?!
I thought you are using Cryptomatte now which requires this method to works.
Anyway, I've tried to adjust the script to save sperate elements which should be as simple as changing one line, but it seems VRay requires some workarounds for that( as stated here )

the following script SHOULD work, but it doesn't and I don't even know why =D
Maybe ^Lele^ or yavor.rubenov could help here, please?

vr = renderers.current
vr.output_on = true
vr.output_splitgbuffer = true
btm_filename =maxfilepath AS string + Maxfilename as string + ".exr"
tempmap = Bitmap 1 1 fileName:btm_filename
save tempmap
close tempmap
vr.output_splitbitmap = tempmap
deleteFile btm_filename

I was using Cryptomatte, however, too many issues. I had errors in Photoshop 1 out of 10 times. PSD manager works, but in bucket mode (although I think he is working on something) so I am using post manager now.

It works for me, no error thrown.

[M.Max]

It works for me, no error thrown.

Hey
Max doesn't show any error here too, but VRay doesn't seem to change the saving path as it should.
could it be something changed with vray 5 and maxscript access?

[glorybound]

Yeah, no errors, but doesn't do anything.

[^Lele^]

bah, i never checked that.
You need to set the actual filename path after setting the bitmap.
So add this line before the last one:

vr.output_splitfilename = btm_filename

edit: before you ask, it's a Max thing with bitmap paths.
