I have just been trying to work out why my renders were failing on a new install of max 2010 and Vray 1.5r3a.
It turns out that the problem was that I had ## symbols in my output path eg: C:\#project\Render\frame_.exr
When attempting to write an EXR, if fails with the Error writing render region to raw image file error, so I thought it was trying to write a region, which it was not. I then switched over to writing a vrimg, and it was attempting to create the file at C:\00700070Project\Render\frame_.vrimg
Each # symbol is being read as a frame number no matter where it is in the path string - I was rendering frame 70.
So I’m rendering to another folder for now, but thought I’d flag the error.
But surely this is not working as anticipated? Why would I want Vray to read a # in a directory name as a frame number? Also, using #s doesn’t allow you to choose the number of leading 0s if once you put it in, it adds the whole frame number for each #.
So somebody wanted to be able to have the frame numbering appear elsewhere in the output string? I would suggest the fix that Vray perform a filter on the string and only use the # if it appears after the last \ in the string (i.e. in the filename, not the directory structure), and thus fix my problem and still allow the requested effect.
Well, one could argue that using ‘#’ in a directory name is not anticipated either But you are right that it is an oversight. I’ve noted this for fixing, however for now that’s how it works.
@3LP - you can do that, yes, only you should use just one ‘#’.
