power failure lost file - but was rendered, can I recover it?

[ispep]

I should have saved it but stupidly made a mistake and forgot as it was sitting in the background whilst I did something else - is there a way of recovering the hip file from what the renderer used previously? Somewhere in my brain is telling me it exports a copy of the hip somewhere to use for rendering. Will that still exist? I need that copy but can't think where it would be.

The renderer doesn't use the scene file it uses archives. If we're talking Mantra then Houdini exported IFD files which are archives specifically for Mantra and can't be opened again in Houdini. When Houdini crashes it saves a file in the temporary directory on the system but if the power was lost and the scene was never saved then I think it's gone. Could check the temporary directory anyway but it'll probably be empty.

Unfortunately I think the hip file's current state before the power failure is lost. Perhaps you can open up a previous file and grab the undo stack in the temp directory and load them in as scripts in order of creation.

 

Houdini does save all operations to $TEMP from the previous save to the current time.

 

As for the ifd file generated by Houdini to feed to Mantra, again that would be saved in $TEMP.

Thanks for help guys, I should know better than to render without saving - what makes it worse is I forgot what I did. Whoops.
