Stop and resume feature when rendering to VRIMG/EXR

[olly]

As I understand it VRIMG/EXR tiles are written bucket by bucket as they complete. So would it be possible for vray to test if the file contains some successfully completed buckets and only render the ones that are needed?

For example job A is rendering via Backburner, about 40% complete, and you need to send job B to start immediately. I would like to suspend job A, let job B start and complete and then activate job A, so it can render the remaining 60%, rather then starting from scratch.

Handling the GI calculations would need some thought, but maybe this approach would only be possible if calling GI from file or if using Brute Force?

I appreciate this wouldn't be desirable in every situation but the option would be a real time saver.

Cheers,
Olly

Hi Olly,

We need to consider this here.
I think this will very useful option, but will be difficult to implement (if its possible at all).

Probably an option to check the existing .vrimg/exr file and start a region render depending on this information is needed.
Otherwise the file will be overwritten.

How about interrogating a render element that is true/false if the bucket was completed?
