Render Region vs. Film Region

Hi

Been looking at the documentation and experimenting, and I still don't understand why there is both a render region and a film region. Right now render region looks more useful since it will keep the rest of the LV data there while it re-renders the active area (where film region blacks out everything else), and you can pull render region data into the render settings.

What advantages does film region have?

Thanks!

Hi,
the great difference between Render Region, and Film Region, is that Render Region doesn’t consider the Max Sampling limit in Kernel panel, useful if most of the scene is clean at a certain Max Sampling, but a portion is still noisy, for example.

On the other side, the Film Region does consider the Max Sampling value in Kernel settings, useful to replace a portion of the image that has a material change, for example.

Not only, in Picture Viewer, the Film Region behavier is the best, since black pixels have 0 impact in render time.

thanks @bepeg4d!

So would it be safe to say that you'd use the render region to investigate problem areas of your render in the Live Viewer and see how many samples you'd need to get a clean render, but Film Region would be more for creating patches for frames already rendered, or is there more to it?

Also, I found the Enable Render Region setting in the Octane Settings, but haven't found anything that calls out Film Region. Does the Render Region area become a film region when it goes to a final render?

You are welcome :)

1. yes, perfectly synthesized :)

2. yes, Picture Viewer works with Film Ragion.

Happy GPU rendering,
