- IR VFB randomly resents to its default values.
- AI Denoiser sometimes cannot be turned off and when it is on it mostly just flickers every second and changes back and forth between the normal beauty pass and the denoised one. (Shouldn't be a driver issue, haven't tried 3ds Max Corona 3.0 yet but Octane AI denoiser that is also based on Optix afaik works fine). I am also not the only one with the issue
- Projector doesn't work in the IR (Would be cool if someone can confirm this)
- Installer is non-compatible with pre-W10 versions. We know that by now though.

Hey Nejc!

No worries, anyone can rant and be snarky as much as they want here! Well, as long as the criticism is constructive... It is always an impulse to get better.

Now to your issues:
  • We know about the installer and Nik has just fixed it at the moment, actually. So it will be included in the next daily.
  • I can confirm that the projector has some issues in the IR. We'll definitely have a look at that.
  • About the denoiser - you are talking you're not the only one with the issue. Can you elaborate? Maybe just post a link, I don't remember anyone talking about it recently (but I don't read the whole forums).
  • By the IR VFB resetting, I suppose you mean the flickering post-processing values, right?

Regarding your ongoing VFB stuttering issues, we have some ideas that would probably help, but unfortunately they mean writing a lot of new code and we have more pressing issues right now. We'll have a look at it some time after the release.

Thanks for getting back to me Cestmir, I appreciate it ;) Like I said, didn't want to come off snarky, just trying to give some constructive criticism.

Anyway...

- About the denoiser - you are talking you're not the only one with the issue. Can you elaborate? Maybe just post a link, I don't remember anyone talking about it recently (but I don't read the whole forums).

Me and my colleague have both tested the latest beta and we both had the same issues. He is running 1080tis while I'm running the GTX & RTX line. Can't ever rule out drivers but we both experienced the same issues right away. Quite extremely buggy because you can't even turn the AI denoiser off. And you are absolutely right, he didn't post here :)

- By the IR VFB resetting, I suppose you mean the flickering post-processing values, right?

Erm, I haven't run into those in quite a while. What I am experiencing is that once you turn the IR on the settings work. When you turn the IR off and then on again the Post-Processing effects get reset. So basically all the tonemapping, sharpening, curves and so on all of those get reset upon restarting the IR :)

And thanks for still looking into the threading issues. I am running out of 3ds Max rental days so it would be fun to have that working :P

The flickering of the AI denoiser also happens to me.

BTW, you can turn the new AI denoiser off in performance settings tab of the render settings (see the pic)

For those with the NVIDIA denoiser flickering on and off - some quick testing I've done showed this happened for me in the Beauty pass only if I had Sharpening/Blurring enabled; or it would happen if I viewed the LightMix in the VFB. If anyone else experiencing it can confirm if either of those were true for them too when seeing the flickering (and that it doesn't happen otherwise), that could be useful info!

Good point, missed that one in 3ds Max as well :)

Exaclty the same for me. Lightmix and post effects effect the AI denoising

When I turn off post effects or lightmix it hardly flickers anymore. It still does it but way less and not in a way that it's annoying.

I'm struggling to repro this flashing issue, can someone share a problematic test scene for us? Thanks,

Posting bug report... may be helpful.
c4d quit when after few IR, changes size and hit render. This was updated in beta 2 also.

Thanks.

Congrats on the new build people :)

One quick note, if the lightmix is turned on the flickering is still happening. Haven't tested it with other passes yet though :)

I'm curious, how does the new bump mapping implementation differ from the old version?

Compare the rendering with and without a dust layer stacked upon the glass base material tag.
Without: no distortion, as expected.
Without: distortion, where from?
Bug?

Win 10, R20, latest daily.

PS
Physical (render, the native one in C4D) does not "do" it.

PPS
Yeah, added dust makes the renderer think the glass object is massive, not hollow, and renders it this way. Detection problem where object ends or something like this.
