cancel render faster

[andrewjohn81]

We have a really hard time stopping a vray render. The max ones seem to cancel ok, but the vray ones do not. It seems that it must finish all the buckets it is working on before it actually will cancel.

If the buckets take FOREVER then it's really hard to cancel. We also get the same thing on occasion with GI calcs.

Is there a quicker way other than ending the task to kill the render?

Use smaller buckets on test renders and that's about it :/
