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

« on: 2024-04-15, 18:50:33 »

Hi there,

I would use a "better" noise level calculation to set in animation works :
If we could include / exclude some objets from the global noise level calculation, this would help to set a better noise-based limit.

Best example is a packshot using some ShadowCatcher white floor :
My object has a quite complex shader, and stays noisy for many passes, while the floor is not noisy after 5-6 passes. But the noise level seams to make some average for the entire picture, and gives a wrong noise level number.

Any chance it will be implemented ?
Regards.

[Max] Feature Requests / Rounded Camera Clipping

« on: 2023-05-25, 12:29:34 »

Hello there,

It would be very usefull to have a "rounded" camera clipping, or even better, a "freeform / spline-shaped" camera clipping.

In Archviz, we always want some nice camera views, but very often we have to play with Tilt&Shift, clipping and position to find the unique millimeter that let us get the picture we need :
more clipping value : the objects are couted-out; less clipping and the walls/floor/ceiling are photo-bombing into the picture.

I'd love to get some rarc-rounded camera clipping, so i can put my camera behind a corner, bu get the scene fully rendered.

And even better, the carema clipping following a spline, a bit like in architectural cuts that are not always straits, but are following some polylines.

Please see attached pictures.

[Max] Bug Reporting / CoronaVolumeGrid does not want my VDBs

« on: 2023-03-24, 17:25:10 »

I'm trying Embergen, it exports VDB sequences.
VrayVolumeGrid open them no problem, and Corona can render that.

BUT, CoronaVolumeGrid keeps telling that the files are empty, no data and does not render.
Any idea about that ? how to setup export / import ?
Vray is not installed on all my PCs, and i would need to DRrender, so i need CoronaVolumeGrid to work with Embergen's VDBs.

Thank you for help.

[Max] Resolved Bugs / Aces output still come back

« on: 2022-11-29, 09:18:04 »

Hello guys,
ACES output is probably good, when you use it from start to finish, but here i have a scene for a customer that was setted without ACES, and with highlight compression 1.2.
Each time i open the scene, i have to reset highlight compression and uncheck ACES.
It comes back each time...

Can you fix this ?

Best regards.

[Max] Feature Requests / Multiple inputs / outputs for material nodes

« on: 2022-10-04, 09:20:53 »

Hello there, i thought about 2 new Corona nodes for materials : Multiple inputs / outputs for material nodes

Let me explain, let's take an example : CoronaUVrandomizer

A typical shader will get base color / diffuse map, roughness map, displace map, normalmap, additionnal bump map, reflexion map, all kind of maps...
If you plan to use modifyer nodes like CoronaUVrandomizer (or triplanar, tonemap control, and some others), after setting the diffuse part, you have to copy it for all other maps.
If any change, you have to make this change on each modif. node
Of course, you could connect some controller float to change all in once, but not so user-friendly, not so "Corona-styled friendly".

So here is the MultipleInputs node : a bit like MultiMap one, you could set several inputs, connect into the modif.node, and set a MultipleOutputs node as exit :
Each input # refers to the output #.

So all differents maps are going into the same modifying node, you have to manage only one set of parameters, and all outputs are put into the actual shader.

Outputs my be like the included AdvancedWood outputs slots, you see ?

Intup #1 goes to output #1
Intup #2 goes to output #2
Intup #3 goes to output #3
 and so one, all of them modified by one node.

Here are the nodes that could take benefit of that :

CoronaAO : inputs/outputs would be for different meshes
CoronaBitmaps : if we need some settings inside
CoronaBumpConverter for different meshes
CoronaCurvature
CoronaDistance
CoronaNormal especially for "add gamma to input", but not only
CoronaRaySwitch
CoronaRoundEdges
CoronaWire

And for sure :
CoronaTonemapControl
CoronaTriplanar for several meshes, but mostly for same shader
CoronaUvwRandomizer for several meshes, but mostly for same shader

What do you think ?

Please see ayttached of what it could look like.

[Max] Feature Requests / Vray Enmesh compatibility

« on: 2022-07-25, 16:54:55 »

Hi there,
It's been a long time that i did not post some crazy requests here.

I've just played a bit with Vray's Enmesh modifyer : incredible !
Of course, as it is a modifyer, i've tested it using Corona renderer, not rendered.

So, please, make Corona compatible with it, please please please !

Regards.

[Max] I need help! / DRserver won't work anymore

« on: 2022-02-17, 12:22:10 »

Hello guys,

Since this morning (yesterday i had a windows update), DRserver is having a strange behavior :
Once started, nothing happends, 3dsmax (2022) is not started, and if i click the green up arrow to start it manually, i get an error in the log (see attached):

2022-02-17 12:16:14   Corona not found in C:\Program Files\Autodesk\3ds Max 2022\plugins, make sure Corona is properly installed.
2022-02-17 12:16:14   DR Server closed

Of course the CoronaMax2022.dlr and CoronaMaxUtils2022.dlt are in the right folder, plus i've removed and reinstalled it, just in case...

Any idea ?
PS : also, it responds to the ping when main PC is searching LAN

[Max] Resolved Bugs / DRserver messing-up with ram

« on: 2022-02-09, 13:26:33 »

Hello there,

I have a strange thing with DRserver (Corona 7.1, 3dsmax 2022, windows 10)

It says ram used 89.1Gb / 63.69 Gb, but the task manager says other things...

[Max] I need help! / DRserver sends 45 passes instant !

« on: 2021-12-23, 11:33:33 »

Hello there,

I guess i should find a way to flush the full DR files on my second PC, here is the story :
- I have 2 exact same PCs : 5950X, 64gb ram.
- I send a render with 35 passes on both (using DR)
- The main PC renders 5-6 passes while the second loads the scene, parse and so on.
- as soon as the 2nd PC starts rendering, the main says "collecting data from slaves..."
- and at final render it is still grainy, saying 54/35 passes, with 45 from slave.

Of course the slave did not render that many passes
The render reflects more 5-6 passes than 35.

Any idea ?
I've flushed the "C:\Users\claud\AppData\Local\CoronaRenderer\DrData" folder, just in case.
Any temporary folder / files elsewhere to flush ?

Please help ;-)

[Max] Feature Requests / Corona standalone but more "Corona-Shot"

« on: 2021-12-07, 13:22:44 »

Hi there,

I wish i could use a Corona standalone software that would act like KeyShot : import objects, and have full IR, corona mat library, and material editor.
And - why not dream large - a simple animation module like Keyshot's one.

My 2 cents.

[Max] Resolved Bugs / UV randomizer no longer works ?

« on: 2021-11-09, 20:29:32 »

Hello guys,
Today i've used the Corona UVrandomizer for the first time since release 7.1.
With 6.x it always worked like a charm, and now, same scene, it no longer works (as instance mode), see picture.

Any idea ?
Regards.

[Max] Bug Reporting / Baking to Texture bg issue

« on: 2021-02-23, 14:16:53 »

Hello,
I'm using Bake To texture for my AO/shadows maps (for some 3DrealTime stuff), and i often get some dark "contours" around the UVunwrap parts.
Even with larger padding.

Solution could be to set the background to white, so i've set it, both in BakeToTexture and Corona Params.
But the BG remains black.

See attached.

I will use alpha, but i can also get some AA contours.

Can you guys let BakeToTexture set Bg to chosen color ?

Best regards.

[Max] I need help! / Underwater God rays ?

« on: 2020-11-21, 13:02:06 »

Hello there, does anyone know how to reach this effects : God rays underwater.

See example.

{Edit] : it seams that volume shader god-rays does not work with caustics, as the ocean plane sends caustics, but blocks the light for volume shader.
