how to get a warning before overwriting existing render

[gui2one]

Hi,
I am trying to get a warning when octane tries to overwrite an existing image.
I thought python script would be the way to go : a simple preframe script checking for an file name. But I can't find a way to 'cancel' octane render in python. With mantra I think a simple ' sys.exit(0) ' does the trick.
How do I do the same with octane ?

Cheers

Hmm, I am not sure if currently it is possible cancel the render from a python preframe script. Probably I should add a command to make it possible. Let me think about it.

Anyway perhaps other user could know a workaround.

thanks, I can stop searching in that direction for now.
