[Max] I need help! / Issue with UV tiling scanned material

« on: 2023-04-09, 08:35:06 »

Hi,

I applied a Corona scanned material to a car paint, then I hit the "Adjust UV tiling to an object", selected the car body and then I receive the following message: "uv and v directions are not orthogonal (the measured angle is 82.3745193 degrees) so the scaling may not be precise. Would you like to continue?"

If I say Yes I can see Coordinates > Tiling values are now populated with non zero values, which seems good at first sight, but looking at the rendering I see the material is still wrong:  material flakes are huge and look unrealistic.
And then if I change U, V tiling values it doesn't change anything in the rendering. So I can't seem to find a way of having this scanned car paint material working fine.

Can you help ?

Thanks a lot guys,

[Max] I need help! / Toon shader?

« on: 2023-04-08, 08:02:59 »

Hi everyone,

I'd like to render an architectural scene with a simple plain grey material + a toon effect, just like the toon effect I used in VRay which was located in the Envrionment and Effects dialog box if I'm not wrong.

Of course I can use a CoronaWire map in the diffuse map but it highlights all the edges and I want the effect to be visible only on the outline of the objects.

How can I reproduce such an effect with Corona?

Thank you in advance for your help,

[Max] I need help! / Animated Sky with clouds issue

« on: 2023-02-02, 03:12:59 »

Hi,

I'm trying to animate a Corona Sky with clouds. I followed this tutorial:

but I don't get the same results.
I've animated Variety and Phase just like in the tutorial but it looks like clouds don't change over time. Their shape remains pretty much the same.
Also I've animated Offset X and Offset Y but clouds appear to move only on the Y axis (Offset X ranges from 0 to 3000m and Offset from 0 to -10000m).

Your help is appreciated.

[Max] Resolved Bugs / Animation stuck on "Transforming vertices..." stage

« on: 2022-12-03, 05:50:27 »

Hi,

I am rendering a short animation (336 frames) with 3ds Max 2022 up to date and Corona 9 Hotfix 1.
Few frames rendered fine but then calculation stopped at the "Transforming vertices..." stage.
I've noticed I have to click on this window and/or resize it to "awake" the calculation process so that calculation goes on again.
If I don't click inside and/or resize this window, things stay as is and calculation of remaining frames doesn't start again.

I've already reached out to Render Manager team for help: here is what they said: "This is a known issue with Corona and 3ds Max 2022. Unfortunately we are not able to help you with this because it is not a render manager problem. We had several similar tickets and we talked with the Corona support about this, to my best knowledge there is no fix for this. Last time the Corona support suggested to switch to the latest version of 3ds Max.
 
You could try to reach out to them, maybe there is fix. Or you could try Corona 9 with 3ds Max 2022."

Please note at the time they wrote this I was using Corona 8.1, so I switched to Corona 9.1 but it doesn't help.
And for 3ds Max I am reluctant to switch to 3ds Max 2023 as it's a pain to reinstall all the plugins and scripts from scratch.

Render Manager also told me to try to disable the Corona VFB: it does seem to work so far but it's not really convenient so I hope you guys know  how to fix this problem, that would be awesome.

Thank you,

[Max] I need help! / Flickering on interior animation

« on: 2022-12-01, 05:29:39 »

Hi,

Here is my problem: I render a short animation of an interior with no moving objects. Very simple scene with just a Corona Sun + Corona Sky entering through a window, lighting a floor lamp and a plaster wall. There is some flickering occuring on the plaster wall. I want to get rid of it.
The texture of the plaster wall has intricate details so the first thing I did was to simplify it a bit by adding a small blur on the plaster texture in Photoshop so that Corona has less work to do with the sampling. also note I use only CoronaBitmaps in this scene, with Filtering > Blur value of 1.0

I also reduced 'Progressive Rendering Limits > Noise level limit' from 7% to 5% (ideally I want the sequence to calculate as fast as possible).

But it's not enough visibly as there is still some noise.

Here are my settings:
_ Primary solver: Path Tracing
_ Secondary solver: UHD cache
_ Precomputation file: Load from file (initially calculated once)
_ Image filter: Tent (width 3.5px, Highlight clamping: 0)        Is this filter good for animation??
_ Progressive rendering limits: none, except 'Noise level limit': 5.0%

My guess is I must lower down the Noise level limit but before I calculate the whole sequence again I wanted to make sure there is no other important setting I miss.

Thank you so much,

[Max] General Discussion / Page file fills up while RAM is not full, why?

« on: 2022-06-20, 14:21:08 »

Hi,

I work on a scene that takes around 40Go of RAM while loaded in 3ds Max.
I have 128GB of RAM. After I've done few interactive renders, and worked a bit on the scene, by adding/modifying objects etc ... I can see that pagefile.sys on the system drive fills up to 10GB. When windows starts this file is only 0.8GB.

Why does pagefile.sys fills up whereas there is still a lot of RAM available? It does not seem very efficient. I would expect pagefile.sys increase only when there's no more RAM available.

Thank you for the help,

[Max] Resolved Bugs / Internal error: Recapturing the mouse in the same window?

« on: 2022-06-17, 14:45:35 »

Hi,

I had a bug using latest Corona 8 Hotfix 1 with 3ds Max 2022.3.3.
Please have a look at the attached file.
At the time of the crash I had interactive rendering running on a not so complicated scene with few lights.
The action I was doing was copying a light. Then the interactive rendering crashed with this error.

Thank you

[Max] Resolved Bugs / Crash at 'Cleaning up' rendering stage

« on: 2022-06-15, 13:10:34 »

Hi,

I try to render a scene with 3ds Max 2022.3.3 & Corona 8 Hotfix 1 on a AMD 3990X PC with 128Go of RAM.

The scene is pretty light:

1.5M polygons total
24 corona proxies
most textures are 4K .jpg, some 16bits tiff (very few, only for displacement)

The scene is 263MB only on disk (Compress on Save disabled), and when the scene is loaded it takes 16GB of RAM.

I render a unique frame, 6000 x 3000 pixels
Physical RAM used while rendering: 33 GB.

The render works fine until the end: 3ds Max crashes on the 'Current Task: Cleaning up' stage.

It's weird because I've already rendered this scene in lower resolution without any issue.
I thought the problem is due to displacement, but visibly not as the RAM consumption is pretty low.

Another cause I can think of is: I try to save the image as '011.cxr'. But there is already a file called 011.cxr on the disk. Can it be the cause of the issue?



Thank you in advance for the help,

[Max] General Discussion / Slow scene loading time

« on: 2022-06-15, 04:45:19 »

Hi everyone,

I experience very slow loading time with a pretty simple scene: 1.5M polygons total, 24 corona proxies, most textures are 4K .jpg, some 16bits tiff (very few, only for displacement).
The scene is 263MB only on disk (Compress on Save disabled), and when the scene is loaded it takes 16GB of RAM.

It takes 4mn10s to load the scene into 3dsMax 2022.3.3 with latest Corona (8 Hotfix 1) and 7s to save on my AMD 3990X, 128GB RAM PC.

Any idea where does the issue come from?

Thanks a lot for the help guys,

General CG Discussion / Convert VRay scenes without a VRay license

« on: 2022-03-06, 12:51:29 »

Hi everyone,

Recently I opened a scene made with VRay. As I don't have any VRay license myself, I wanted to use the Corona converter in order to convert the scene for Corona renderer.
But it didn't work: materials were not converted into Corona materials as I expected.

Does it mean I have to buy a VRay license to convert scenes from Vray to Corona?
Or can I just use a trial VRay license instead?

Thank you guys,

[Max] General Discussion / Changing the Corona material library location?

« on: 2022-03-01, 06:58:03 »

Hi,

Currently the Corona material library location is: C:\Program Files\Corona\materials

It's not very convenient as I could save some storage on my system disk by moving it to another drive.

So I moved this folder out of the system drive, and when I launch Corona renderer I have an error message saying I must install the library, but I don't have any option to look for the new library folder location.

Is there anyway I can move the library out of its default location?

Thank you,

[Max] Resolved Bugs / Max silently crashes

« on: 2021-12-16, 04:00:24 »

Hi,

I was running latest Corona 7 hotfix1 on 3ds Max 2022 v24.0.0.923 (the latest 3ds Max 2022.3 was not installed yet at that time).
I did Customize > Custom Defaults Switcher > and I chose ame-light instead of DefaultUI Dark theme. But at the next start of 3ds Max, changes were not taken into account: it sticked to Dark theme.

After I've post my issue on the Area forum https://forums.autodesk.com/t5/3ds-max-forum/custom-defaults-switcher-doesn-t-work/m-p/10824849/highlight/false#M198937, I've been advised to uninstall Corona and to reinstall it, which I did. I also installed latest 3ds Max 2022.3 update (v24.3.0.3404).

Now I am able to switch from Dark theme to the light one without problem but, when I want to switch from the Defaut Workspace to something else (Design Standard for example), 3ds Max crashes again.

Are you aware of that problem, and do you plan to implement a fix for it?

Thank you,

Hardware / Hardware optimization?

« on: 2021-12-14, 08:38:25 »

Hi everyone,

I come here to gain advice on my machine as at the moment it runs with standard BIOS settings and I want to slightly overclock it to get the most out of my hardware.

Here is my machine specs:

* ASUS PRIME TRX40-PRO S
* AMD Ryzen Threadripper 3990X
* Noctua NH U14S TR4-SP3, push-pull configuration (with one additional fan)
* Case: Be quiet! Silent Base 802, with 5 x be quiet! Silent Wings 3 140mm Fans
* RAM: 128GB G.Skill Ripjaws V 3200MHz (4x32GB | 16-18-18-38)
* PSU: Corsair AX1600i
* MSI RTX 3060 Ventus 2X OC - 12GB GPU

Currently the cpu runs at 3100MHz and RAM frequency is 1333MHz.
But AMD claims a Max. Boost Clock of up to 4.3GHz, and G.Skills says that my RAM tested speed is 3200MHz ... I'm far from these values.

Can you tell me what's the best way to get closer to these values?

I've heard of PBO: what's the best way to enable it? By using AMD software 'Ryzen Master' in Windows? Or by tweaking BIOS settings first? Both?


Thanks a lot in advance for your help, much appreciated,
