save each model part as they are created

I think this may have come up before.

but I’d like to be able to use the mesh parts that have been created already if i cancel it or it crashes.

quite often i have a lot of trouble on the last couple of parts. I’d like be able to cancel it and use whats there.

this has wasted a lot of time in the past, it a bit annoying to be running it for 2 weeks and get nothing at the end. when i could have had 90% after 4 days. esp when it happens a few times in a row :(. can quickly go through more than a month between successful outputs.
