Pretty cool hidden Vray feature

I read about this on the Chaos forum a while back and for some reason I never tried it, but I did yesterday and it's pretty cool. This hidden feature gives you the ability to have a thumbnail representation of all or some of your renderings (it's your choice) that you can recall by double clicking them. When you double click the thumbnail it loads the rendering back into the VFB for a really nice way to compare multiple renderings.

 

After using this for 30 minutes, I found 3 or 4 things that could make it better, but indications are that improvements are coming. This feature is both undocumented and unsupported, but nonetheless, it's cool.

 

Here's the way to get at it...

 

"...it's there just not activated by default. Create an environemt variable (for windows, not max or vray) with the name VRAY_VFB_HISTORY and set the value to 1...then you get an additional icon in the VFB on the bottom

 

Regards,

Would someone mind explaining to a Luddite like me how I go about creating an environment variable for windows. Would love this feature but have no idea how to do the above.

 

 

 

Thanks,

Hey Everyone,

 

Just a reminder to anyone who may get carried away

with this that each image will chew a chunk of your

memory!

 

Just know that someone is gonna save 30 renders and

then wonder why the scene crashes on render. :eek:

Actually with the way Vray does it, it writes temporary .vrimg files to the hard drive and then loads them back up when you need them. I just did a test with 35 renders in the history and it didn't change my available RAM at all.

i thought that may be the case, but.... are you definate on this Brain? it crossed my mind that perhaps the images are saved out as temp files and just referenced back in or are they kept in memory / RAM?

 

looks like a nice feature, unfortunately were still waiting to upgrade to RC5

Make sure you have a large portion of your HD available for these or delete the older ones. As I understand it, Vray is saving out full float images which can be huge in terms of file size per image. You could be looking at saving multiple iterations of 50-100 meg image files. So if you start noticing that your C or D drives are getting kind of low on free memory, I'd start deleting these images. There is a memory limit that you can set in the frame buffer settings, but it still may or may not work. So just be careful and monitor your drive spaces.

 

Just as an example I saved out a 320x240 .vrimg and it was already 4 megs, so imagine what a larger size image would be.

What is a environment variable for windows?

This feature is indeed a great addition to Vray. One question. Say your mid render on a frame and you double click one of your previous renders on the history dialog to display it in the VFB, is there a way to revert the VFB back to the frame your currently rendering?
