Ok, good point about alpha stage of the software. I may got carried away too early straight away comparing to cycles and corona.B.Y.O.B. wrote: ↑Mon Sep 03, 2018 5:07 pm Just a reminder: we have added BCD in one of the v2.1alpha releases. Since we are still in 2.1alpha phase, the whole denoiser integration is alpha software, very new and rarely tested.
So the kind of feedback you provide is very valuable, and it is expected that a new feature might not work properly in the alpha or beta phases.
Since we have only integrated BCD, not developed it ourselves, we are not really familiar with the BCD source code and can't say immediately for example how hard it would be to port it to OpenCL to speed it up.
The blurring of dark image areas is also a problem where we would not know immediately where to look in the source code to improve this. Maybe you can ask the original BCD authors about this?
Here is the official BCD repository: https://github.com/superboubek/bcd/
You can create an issue there. It's probably best if you attach a test case that the BCD authors can easily reproduce.
Looking into the BCD, googling comparisons etc got me thinking that it is actualy working as it is supposed. Which could mean that lowering it's memory consumption and porting it to opencl might solve some issues but it is still not going to help the quality which is not in your control.
So this gets me thinking, are there other options? You don't want nvidias denoiser cause it's nvidia only. So are there some other options to replace BCD and is this even a posibility?
