Auto Extract all channels from VRIMG?

Hi all

I have a VRIMG file with lots of channels. Currently I’m extracting from that file each channel 1 by 1. There must be an easier way (In render elements they were renamed to some funny names)

2

that is what ProEXR does. I used it last night, for the first time, and it worked like a charm.

yes I know about that. I meant is there a way with the vrimg2exr tool to do it? (Some of us are stuck with limited resources and can’t get each and every little plugin or script that comes out) even if it is only $5
If my main software cant do it, and I cant do it with free scripts, then it aint gonna happen

I’ve been looking at ProEXR for a while now, and it does look interesting, but the boss won’t agree to it. I’ll have to find another way to do it.

if you just want to extract the channels from a vrimg, search this forum for Shimakaze’s Tools. theres is a vrimg2exr batch conversion tool

I’ve tried that tool, It doesnt extract elements that have been renamed

you can edit the batch-file to your needs…but everytime you change the channnel-names it won’t extract automatically , thats right

O yes sorry I was being thick.

Didn’t think of editing the batch file
Thanks :slight_smile:

Guys, could you explain vrimg to me a bit. I mean what’s the point in saving to this format if “nothing” can open it? So you have all channels in one? That seams ok. But someone also wrote that you can save all the channels from elements to exr if you manually type *.exr. I tried it but didn’t happen. It DID save an exr file and I can open it, but no layers. Is there a procedure? Right now I just add an element.

The exr have all your layers (but photoshop and most other doesn’t show it) If you want to see your layers in Photoshop you need to get the ProEXR plugin for Photoshop. Or get Nuke which is in same price range and Max (and it can open EXR with layers (all channels).

Or instead of just renaming the vrimg extension to exr, just below that is a thing that says save channels seperately. I just prefer the vrimg file. No technical reason, just like it that way

This would work for a single render, but how do you work when you want to render several cameras (views) with a batch render? What is the general work flow here? I have a problem because if I turn on VFB MAX batch renderer doesn’t save my elements, if I turn off VFB I get the elements but then I get low dynamic range exrs I think, because they don’t blend well to the background (a white edge even if I defringe), also if I adjust exposure, I see there are no details in burnt areas.
