As a Feature Request, I would really appreciate to make cropped renders ... rendering only a very small selection of a scene.

My main point for not using MonteCarlo algorithm is the amount of noise, which is kind of unpredictable. I would like to select a small area of a scene, to render this part for observing the amount of noise, and to adjust the settings. Depending on those values, I might have one very long lasting final render, but right now I have multiple ones :D

Regards,
Voulxe

I do not know if this works, but try setting your volume with Limits (bounding box) on Rendering Engine Tab

It does work ... a quick input of a single 'Z'-ordinate for the top right corner ... approx half the scene gets rendered, using approx half the time.

Two small drawbacks to a true cropped render: Not very intuitive / The ambient light changes

But for now it is a great step forward :)
