1) Message boards : Client : Cycles Denoising on split frames (Message 15299)
Posted 1 day ago by Profile ChameleonScales
Ok but I was not talking about post-processing effects. Compositing locally is not a problem at all (as long as you download your frames in non destructive format, with high dynamic range and render passes).

What is problematic is the new denoiser in Blender 2.79.
This feature is not a post-processing feature, it's a rendering feature. You cannot use it after the render is done, it can only be used at render time.

For that reason, if we don't use some trick to prevent the seams, it can simply not be used on split frames, even locally after downloading the frames in EXR format.

However, contrarily to effects like blur which can vary drastically and unpredictably according to the values set in the nodes, denoising doesn't require much margin, provided that the artist used it the way it's supposed to be used, which is : remove the last bit of noise. Not smooth out a crazy noisy image.

Removing the last bit of noise with vs without the denoiser is a matter of going from 3K samples to 10K, which is a huge difference of render time (More on that here)

So if you use it correctly, you shouldn't need a margin bigger than a few pixels (like 4 or 5 per tile) to prevent seams.

I have this idea for avoiding seams when denoising on split frames, which is to add a margin on each tile and blend the margins between tiles gradually when combining them.
It sounds crazy but I don't think there is a better way nor will ever be.


If it sounds impossible to do, I think it can be made possible this way :

- The renderfarm's software would only add the margins (expand the borders on each tile, except for the actual camera borders which is neither possible nor needed) and once the rendering is finished, provide the tiles as they are for download.
- the session page would provide a link to a blend file containing the node setup to use for combining the tiles, so the user could do the compositing on his local machine.

What do you think ?
Do you have another idea ?

Sheep it has disabled denoising for split frames because it would produce seams on the edges of the tiles.
How does BURP handle that at the moment ?

Is 2.79 supported ?

I selected exr as the output but forgot to also have ask for it to be enabled in the description.



I'll reupload it.
But why is the setting not kept otherwise ?

My small projects are always hanging at 95% for days while all the rest was done in a couple hours.
I must say this is pretty frustrating.

Thank you !

I uploaded a file and realized I had to change something before submitting it so I reuploaded it (I think twice).
Now when I try to upload the file an almost blank page appears with only the text :
Fatal error: Uncaught [[o:Exception]:"java.lang.Exception: Invoke failed: [[c:Session]]->createNewSession((o:int)[o:Integer]).

How do I "reuse a previous one or cancel them before creating new ones" ?

I couldn't find such an option anywhere.

Anywho, I'm sure BURP is also collaborating with NASA along with Creative Shrimp and CG masters to give us those so called new "Photos" of Jupiter :



But props on the amazing procedural texture though. I wish they made it available in the space VFX course.

Seems it was removed from there. Dunno if it was because of my post.
I'm not particularly following SpaceX or enthusiast (or impressed) about what Elon Musk does and some things about spaceX can look a bit curious from the exterior but this is simply ridiculous.
Unfortunately as Elon's tweet shows, being sarcastic about conspiracy theories mostly spread them even more (some papers published "Elon Musk admits using CGI" after that) and that's why I thought it's not a great idea to put this on the front page.

It is, but given the complexity of the scene, if I optimized it using better techniques and the latest version of Cycles (with denoising and adaptive subdivision) it would still take a while because I need the trees to look all different and there are a LOT of trees.

That's strange because I started the render locally and it went up to 11GB before path tracing, did I miss something about how to determine the memory usage ?

This is just a joke but I find a bit weird to have it on the front page of the website.

Amazing, more than I could ask for.
I didn't know these kind of curves were also polynomials. You can really do all sorts of things with polynomials !

Of course you're right ! I forgot we can use exr with BURP.
Here's the comparison :

This is to know better when to expect a submitted project to be accepted, so that I don't check every 30 minutes if it's the middle of the night for you (that doesn't mean I expect you to react in minutes during the day anyway).

Glad to see my little versus brings people here and also to see that I need to clarify some things. So I just added a precision about that.
In case I still didn't give you the link Janus, you can read it here and tell me if anything bugs you or if you'd have anything to add.
