Look at my old test. This is exactly where
Image adaptivity will work perfectly.
https://forum.corona-renderer.com/index.php/topic,1448.0.htmlIt's a white room, but with some strong, bright lights + DOF = very difficult to clean up!
The room is almost noise free, but I needed 20 minutes to have a decent DOF.
With
Image adaptivity, I think (I hope) we will reduce this time, drastically =)
Also, in the first image, after 30 hours, the bar was perfect, but the DOF, on the metal bar, was horrible =)
When we will have a new Corona version, I'm very curious to test my old scene (white room). You can download the scene, in the attachment.
