Lawrence D’Oliveiro presents a patch that allows YOU to pick which part the render will work on next. This is especially useful for complex scenes that take a LONG time to render.

This is an example in action of a patch I made to Blender to let you click on a render in progress to choose which parts you want to see next. That way you don’t have to wait for the entire render to complete if you just want to check one part of it.

Great!!! Hopefully we will see it by default and in cycles!
I agree
Fantastic!!! And fully agree with Agustín
You can already render a selected area you wish to see rendered without rendering everything.
In camera view, press Ctrl+B then select the area you wish to render.
Select rendered view as you would for rendering in Cycles in real time.
It will then render only the part of the image you selected!
True, but sometimes, you want to see more than one spot of your render at a time.
It would be even better if anyone who mentioned using Ctrl+B also mentioned how to get *rid* of the selected area and go back to rendering the full image ;-)
To clear the Ctrl+B border render, it's Ctrl+Alt+B, for anyone interested.
That is awesome. Especially when you have many cores and the tiles are small, such a priority really works great. The ctrl-b thing works well enough when you want to inspect the lighting on a specific spot, but this is really useful for when you have more than one problematic spots in a render. It would be really great if there would be a simple opengl render in the background that get's progressively replaced with then cycles render. That way you know where to click. How hard would that be Lawrence?
That's a great idea PhysicsGuy. Got my vote!
Great work Lawrence! This is amazing.
Excellent suggestion!
I just want to wait until I get some kind of review for the existing patch. Then I can think about getting more ambitious. :)
I only just realized I wrote "cycles render" in my post. I meant that the real render could progessively replace the opengl one. In this case, the real render would be the internal render.
Bloody hell. That modest little video has already been viewed over 2,000 times, and I only posted it less than a day ago. I won’t say I’ve been Slashdotted, but I’ve been Blendernationed. :)
By the way, the video editing and titling were done entirely in Blender. I just used FFmpeg to do the initial screen recording and the final encoding. FFmpeg, like Blender, is another of those neat tools I like to use at every opportunity.
Some pieces of software just make you feel glad to be alive. :)
2000 views is not bad. BlenderNation keeps getting bigger and bigger!
2000 views. Well, it shows that you had a good idea!
