I still haven't made more tools for cache files but there is some more detailed info in new manual about these cache files here + the larger picture about entire system.

Thats great! Thanks!

I have improved the noise reductions for HDR such as this one! 2x less noise in the same time! No iteration time increase. Other HDRs that were already good dont' become worse with this modification.

That sounds amazing!

May I post the "before/after" image with this your scene on the news page related to the next 0.593 fix-release? Will also insert the link to your Behance

Sure, you can.

I am very excited about this update!

I haven't read all the details yet, but as far as I know such a thing works for early samples.

Yes, that should be right and as you said, that would be very useful for preview renderings in the IPR.

Btw there is more recent achievment by Eric Heitz https://eheitzresearch.wordpress.com/762-2/ Jacco Bikker did it for his Lighthouse 2 path tracer project (real-time): https://twitter.com/j_bikker

Ver interesting, thanks for these links!

Hi,

I am not much the technichel guy, but this looks very promising and intersting.

Could CentiLeo benefit from this?

I have read, that Corona is working on that at the moment and that will let the images look less noisy.

Very interesting stuff!

when I think about an idea of making HDR per material it doesn't look like nothing

Quote
You may create them and assign different .hdr/.exr files and make on/off for Camera, Diffuse, Reflection, SSS, Shadow Catcher, Transmission, Translucent. For example som Sky object Environment tag has only Camera channel = 1, others are zero. The second Sky object has only Diffuse = 1 and others zero. And this way you may assign different lighting to diffrernt channels.

I do this very often. Nice technique!

It appears randomly and in different places.

Quote
There is a problem to find solution because the bug changes positions and not always reproduced in the same conditions.

Exactly! Very randomly.

Quote
Maybe some of geo compression scheme is the reason. But we need time to fix that.

At the moment it is not a huge problem. I can delete the frame where is a dot, or edit it in photoshop quickly. I hope your Idea will work.

Quote
I remember it appeared even few years ago http://centileo.com/forum/messages/forum19/message569/111-centileo-for-cinema-4d-0483-available-mult... In my constant tests I randomly see the problem probably once per 2 weeks in different situations. After re-run it dissapears

Yeah, im sure this can make you crazy.

Hi,

it looks like, when I render an animation, that few frames are becoming black dots here and there. I dont know, what cause this.

I will send you two files, and if you look carefully, you will notice the dots, like in an old movie.

Any idea?

Quote
1) to erase not-needed lights from HDR image by user.

Thats a good Idea!

Quote
2) wait for some my adaptivity fix which may help and will cost probably +100Kb of memory consuption + tests/debugging or something like that.

+100kb is nothing

Quote
Research has shown that HDR resoultion issues were not issues in that case. But! There are 4 drawn light sources in your HDR. You may see them if move the camera outside the window.

Thank you for this information! Its exactly like you said. I should import a HDRI with one main light source the next time. Never thought that, HDRI's can produce this kind of issueses, but makes totally sence.

- Fixed bug for lost frames during animation rendering in PV

Works like a charm now, amazing. Thank u much!

Quote
Such property can be needed in animation denoisers.

Optix for now cant denoise animations without flickering and I hope that will change in near future! The corona high quality denoiser for example works in animations suprisingly good!

Quote
How did you make it working with black 1/2 frames?

I have used a slowmotion plugin to fill the missing frames. On slow camera movements, like in the animation. It works quit well.

Quote
There should be no flickering, it uses no caches. Flickering may appear in cases of caches (especially irradiance cache with some large gather radius).

Yeah, makes sence. No cache, no flicker.

Here we go with a noisy short animation test. It looks like there is not much flickering. But would be better visible, if I let it render for much longer.

Btw: The "insert video" function seems not to work. Would like to insert the player directly.

If HDR is high res, has small area of light with very high intensity - there can be a problem.

Exactly, this kind of HDRs can give an amazing lighting mood sometimes, with stronger and longer shadows.

Great to see this tests, very interesting!

Quote
Lowres/highres of original HDR shouldn't be influential, but the resolution of sampable HDR is.

Yes, I have tested the HDR in lower res, there where no difference.

Quote
So I am calm for that CentiLeo special GI sampling algo. Just need to improve HDR initial procession

I am excited to see the improvements

Quote
Btw, it lags on my PC too! Very slightly. The cooling system works too intensively and with the same rythm.

Good to know, that this doesnt happens just on my side!

Quote
At the same time I like Flakes a lot more.

Yeah, I need to test these out.

Quote
Please, can you send me a scene file and HDR for experiments to info@centileo.com

Sure, sent!

I hope you can find something to optimize and get more speed

Here we go with the next test. I played with the "scratches" shader. I am amazed of this shader.

So easy to give every material the little extra for more realism!

Quote
For earlier versions I just need to recompile earlier plugins (there were some issues there). I hope to do it tomorrow

Perfect!

Hi,

when I render a animation, every second frame goes black. It doesnt render, just get black and jump to the next frame.

Let us say, in this example Im going to render a 550 frames animation. On the end, there will half of the frames be missing.

Tried to double the total frames to 1100, but on the end, the animation was finished in the middle, the half of the frames were missing and the rest were just hunderds of frames with just the last not moving frame.

Is there a way to solve this issue at the moment?

The portal version took few seconds longer. Both were rendered at 10 iterations.

Quote
Maybe I will move it to Diffuse.

Yes, that would make more sence to place it there.

The dark areas takes too long to clean up. At the begining it cleans fastly but than it takes and takes.

But that is in every renderengine the same with HDRIs.

Mostly I work with a white sky or area lights infront of the windows.

HDRIs can create amazing moods sometimes, but for me speed is more important.

Here are 3 different versions. All are rendered for 1min. The day scene above was rendered for 2 hours and the night version rendered for 40-50min.

Hi,

I have recognized, when I am minimizing the IPR window and later maximize it again, it will be black.

It is still rendering. I can see the result when I save the render.

Here we go with the night version of the interior. I have used a blue sky here. The render was much faster compared to the HDR lighted version.
