Hi,
for those of you who have access to daily builds, functionality of bucket rendering has been partially fixed, and it is now very easy to use.
Basically:
Subdiv AA sets the base AA quality.
Adaptive threshold sets how significant difference in the pixel value needs to be for adaptive refinement to occur.
Adaptive steps set the amount of adaptive steps each of which will refine the bucket further.
So if you set subdiv AA to 4, adaptive steps to 4 and adaptive threshold to 0.02, then:
- initial adaptive step will be rendered constantly using 4 subdivs per pixel
- next adaptive step will sample any pixels with difference larger than 0.02 with additional 4 subdivs set in subdiv AA
- and two more adaptive steps will proceed looking for any pixels with difference larger than 0.02, and keep refining them using 4 more AA subdivs
This should be pretty easy to control. Bucket rendering is no more affected by any of the progressive rendering limits, and will stop once all of the adaptive steps finish.
Now i would like to ask you to test bucket rendering, and see if it performs better in some of the scenes. As bucket rendering has some basic adaptivity implemented, it could be beneficial for example in scenes with strong DoF :)
Thanks in advance :)
