[Max] Feature Requests / Re: Render time and noise level to be shown in saved CXR render file

« on: Today at 09:16:01 »

Corona has always been a bit stingy with stats data (and logging) and a convenient option to access it would be nice (at least in CIE), yes. Additionally all stats should be included in EXR metadata as well at best.

But Corona already stores the most important info in CRXs. Use exiftool to extract it like:

Code: [Select]

exiftool -CoronaStats* -CoronaRenderStamp* yourfile.cxr
And note that the renderstamp is always saved into the CRX, even when not activated in the render settings. So you can use it to store various data additionally. if you write a batch with something like above, you can even integrate it into windows explorer context menu of CXR files (image).

[Max] Feature Requests / Re: Noise level based on inclu/exclude list

« on: 2024-04-16, 08:43:29 »

Hi,

yes, this:

You can as well reduce the adaptivity recalculation to less passes than the default 5 - this will calculate the noise level more frequently, if it helps.

Do this everywhere and in every scene, especially doing animation. But even for stills it's better to use 1 here (it is a dinosaur default setting from old Corona times, it does more bad than good).

Additionally, activate the CInfo_SamplingFocus render element FYI to see adaptivity in action.

Hi,

yes, hotkeys to call a macro script seem to be blocked when Corona is rendering unfortunately (invoking from the scripting listener works though). I don't know why, sorry.

Hi,

what do you mean by "invalid"? Just checked, works as expected here (v9 to 11). Which Corona version are you using?

Is this what you mean by "what is vfb state"?

It is about being visible, maximized, minimized or even about getting position and size (and the currently displayed channel at best). In one of the first macros I created for Corona (10 years old) I have found a note, that it is "unfortunately not possible" to get the state of the VFB, and as a result, the macro button cannot react to the current VFB state (isChecked).

Hi,

thanks for sharing your experience, I remember requesting exactly this:

a custom map node that loads colour libraries from csv files

as an additional feature for the Corona Color Picker as soon as it was introduced, but withdrawed it because standard Max material libraries appeared to be good enough and are generally usable. Still something interesting though :)

Hi, try

Code: [Select]

if classof renderers.current == Corona do renderers.current.vfb_type=2

0: none
1: 3ds Max VFB
2: Corona VFB

so weird how its only started happening now

I remember stumbling across this for the first time after quite a few years using Corona - in a scene not even relying much on GI apparently

I am losing my mind

... and I felt similar :)

Hi,

you are most probably a victim of MSI:

stand out in the UI

Yes, it indeed does :) And looks ugly. I understand the purpose to "promote" CoronaPhysicalMtl those days. It comes as a bad hack affecting basic stuff though. All that renaming materials/maps in order to place them differently in any listing (or to avoid clipping) is crap imho, but go on.

[Max] I need help! / Re: About RAM errors when using a DR server.

« on: 2024-04-05, 10:06:34 »

If you are connected via VPN, depending on the VPN system, it could be everything. You have neither shown how it looks in the vfb when it fails nor provided any log files.

You should at least go through this at first:

https://support.chaos.com/hc/en-us/sections/9924340063121-Distributed-Rendering-Troubleshooting

Yes, and create a ticket with all relevant information.

Thanks for looking into it anyway,

Edit: Oh, and if this has been done just to have CoronaPhysicalMaterial on top of the material list using the material editor, please reconsider. It crumbles the basement and adds confusion just to achieve some UI effect.

This should at least ought to been some announcement in the forum. Having knowledge of this bug, not publishing it, letting customers scratch their head and having a bad time when producing output appears like bad product management to me. I'm not reclaiming the public bug tracker we once had, but be more verbose please.

Now, what is this all about. Memory issues of DR slaves or slaves not working generally? The "n/a" is there as long as no master has connected to the slave, nothing special. If #2 does not work even when using a simple scene, try to switch off the windows firewall and see if it is working without. If so, add a rule to the firewall for drserver.exe.

Btw, kind of bug report/annoyance:

Code: [Select]

showclass "Standardmaterial.*"
showclass "CoronaLegacyMtl.*"
showclass "CoronaPhysicalMtl.*"
showclass "_CoronaPhysicalMtl.*"
apropos "CoronaPhysical"

managed to get the script working.

Nice! Amazing enough what you got from the bot. Not sure about your real world scale approach, since it is not explicitly used when creating the plane but later on when creating the bitmap. So I'm attaching "my" version with fixes and real world scale for both, the plane and the material.

As for looking deeper into maxscript objects/classes:

https://help.autodesk.com/view/MAXDEV/2023/ENU/?guid=GUID-879ECFAD-7928-44B3-BCD7-276D53C89B52

where you can find the showProperties command mentioned by Avi as well. Shortest version is creating an instance and show its properties in one go like this:

Code: [Select]

show (CoronaPhysicalMtl())
show (CoronaBitmap())


Good Luck
