We still need infinity plane in Corona to make it in geo...not sure if making absurdly large plane (I think there is way (modifier maybe?) to make it uber-large only during rendering) can get you close in look, but worth a try.

Actually such option is embeded in plane primitive itself, it's called render multipliers.

wow thanks!
The answer is right in front of your eyes and yet I have always been frustrated with ridiculously large planes and the resulting shitty navigation in max...

[Max] I need help! / Sampling Focus, Lights

« on: 2018-10-25, 16:25:16 »

Hello, I have a little problem here.

It seems that the "Sampling Focus" is especially strong on and around light sources (e.g. front lights of the bike), while other noisy spots never become clean (area above the front lights, helmet reflections). I know there was an oversampling of dark areas in the past, but now it seems to behave the other way round in some scenarios.

Does it make sense to turn off the adaptivity in such a case?

I don't know why, but I have the feeling that the good old "bucket mode" used to do better on "DOF highlights" and other special cases than the "new" adaptivity mode.
It was said that it will never come back... so, are further improvements of the adaptivity algorithms planned for future releases? :)

you could increase the sensor-size to simulate a medium-format (~45-90mm) or large-format camera, wich should give you a more shallow DOF with the same FOV and f-stop... you have to increase the focal-length to get the same FOV with a bigger sensor size. that would be the photographic approach...

or you could just lower the f-stop value :)

It gives me error sign for missing optix dll.

Hi Danio, the install is an option in the Corona installer, you'll need to use Custom and enable it :) It's off by default. It should then install all NVIDIA Optix stuff that you need. Be sure drivers are up to date as well.

That missing dll actualy affects not only CXR saved with new denoiser but also it affects standalone image editor and preventing it from startup. And the funniest thing that the dll with the right name (optix.51.dll) is actualy present in Corona/optix folder.

the image editor starts up, if you place a copy of the optix.51.dll next to the image-editor exe
well, the denoised cxr looks a bit weird :)

Hey! My dual Xeon at work has the same problem from time to time :) I'll try to make a minidump the next time this happens...

you can try to add some noise back to the final render... not sure how this will work out...

e.g. https://www.slrlounge.com/remove-banding-photoshop/

I cranked the images up a bit and now it becomes clear that the denoising in the final render introduced some banding...
often a little additional noise is used to reduce banding artifacts in 8-Bit images

some options:

1. decrease the denoise-amount to leave some noise in the background to reduce banding
2. add a "beauty" render element with denoising set to 0 and mix them in the post
2. save as 16-Bit Half or 32-Bit Float EXR and dither in the post when converting to 8-Bit

any news on the very high memory consumption when rendering large stills?
imho, this is one of the biggest problems in production...
i have just looked at the trello-roadmap and it seems that this will not be solved in v2? :/

[Max] Resolved Bugs / Strange Artefacts with Sharpening

« on: 2018-01-31, 17:08:16 »

i just discovered a strange bug when using Sharpening/Blurring:

Framebuffer looks great but the saved EXRs show some strange horizontal and vertical artefacts when there is a bright light source...
if i disable Sharpening, everything works fine.

[Max] Feature Requests / Re: Ability to lock the size of the VFB in interactive mode

« on: 2018-01-12, 13:54:59 »

Hello everyone,
I come back to my post because really, this window that grows steadily is really unbearable. It would not matter if you worked with three polygons in the scene. But with Forest and Railclone, millions or billions of polygons, it's really very annoying.
The idea is just to add on the VFB an icon like a padlock for example, locked by default. That's all, nothing more.
If this is not possible technically, it would have to work with a normal window, like for a rendering of production.
Thank you !

Again, +1 ! :)
