[C4D] I need help! / Re: Cryptomatte problem.. jagged
« on: 2023-07-21, 15:08:59 »
sto usando EXR-IO con il livello automatico direttamente come maschera, esattamente i livelli creati di cryptomatte per tutti gli oggetti

translation: i am using EXR-IO with auto layer directly as mask, exactly the created layers of cryptomatte for all objects

Hello Romullus, thanks for the reply but I am writing the post because I am in PS with exr open and I always see everything jagged in the channels created by opening, importing and separating EXR. What I see "colored" is the same that then automatically creates the crypto exr with separate channels.

The selection layer from cryptomatte (separate layer by exr) are jagged

[C4D] I need help! / Cryptomatte problem.. jagged
« on: 2023-07-21, 10:38:22 »
Hi guys,
can someone explain to me why the cryptomatte comes out jagged?
I attach the image of what I get despite the noise being at 3%, official version 10 of corona.

Guys I made the render with tonemapping off (file 1.jpg).
The scene approaches that of 3dsmax, but at the same time it always remains distant from the point of view of the shadows and their strength.
I am attaching this test render made following Stefan's instructions

-update-
Maru sorry but I have only now seen your answer, in part I have already provided these new elements.
I know you repeat yourself like a broken record, I always pay close attention to advice and by often reading the forum I always treasure everything you provide. At the same time, if I notice problems, I can't help but point them out and I always try to provide as much information and tests as possible, both to give a more accurate picture of what I'm experiencing and to clear any doubts.

Thanks guys all for the replies!!!

Since I use both software, I'm pleased to investigate this "aspect" both as a personal doubt and as a possible solution to be adopted at a working level when it occurs.
As far as the question of color is concerned, I believe that this does not affect the calculation of the shadows of the scene: if I compare the results of the two renders, the color of the sky seems very very similar to me, instead what differs are the shadows which are much more contrasted and strong in c4d.. i guess this is due to the calculation of the light which affects in making the process of 3dsmax speed up compared to c4d.
Anyway, as soon as I have a moment, I'll send you both scenes but you can easily do a test using any scene outdoors and setting exactly the same settings in both software as I did, nothing in particular.
As for the time, to be picky, going from 13 minutes to 16 minutes results in +24% ehehehe :) :)

Not being able to understand where to load the images to make the visual as your "compare" I am attaching both the clean renders and the screens of the relative VFBs.

As requested I rendered the scene with 100 passes:
- the sky has no clouds and all the same parameters.
- both renders are path traced as requested.
- same material (all settings).
- same cameras (all settings including color mapping).
- everything in the scene is identical.

Comparison:
- tests show that shadow quality is markedly different.
- the tests show that the times are not at all identical, in fact we have 3 minutes less in 3dsmax than in c4d.
- the rays and all the other calculations are almost similar as seen also in the screenshots.

No other programs were used during the render tests. I hope it will be useful for you..

 Thanks guys

Hi guys, thanks for your fast reply.

Excuse me if I allow myself to make some clarifications because perhaps you have not paid attention to the posted images and what is written inside them:
- one situation is with "shadows active and affected" by clouds..
- one situation is with "shadows unaffected" by clouds..
- the mapping of the tones and the colors are IDENTICAL.. don't say that the color changes the tone or anything else, because I wrote from the beginning that all the settings and the parameters are the SAME, the scene, the materials and the settings are all perfectly identical ..
- in the situation where the shadows are not influenced by the clouds, there is always a notable difference in yield and times..

Both versions (3dsmax and c4d) are with the release 3 apr 2023 (as stated in the upper part of VFB).
Both tests were done by rendering ONLY the scene, without doing anything else otherwise it wouldn't make sense to make a comparison.
The machine is equipped with a Ryzen 7950x processor and 192GB of DDR5 ram, with the operating temperatures of the cpu during the rendering phase are constant at 69°/70° with 100% use for both 3dsmax and c4d.

I'll immediately do the test render with 100 passes and post both the times and the yields. Let's get to the bottom of it now!

Question: If the motor is the same, the version of the crown is the same, how can it calculate the secondary GI differently to such an extent that it changes the rendering of the scene?

Good morning lads,

out of curiosity I did a comparison test between the C4D and MAX render engine and I noticed some really substantial differences on which I ask for your opinion (same scene, model, render settings, light, same camera parameters, materials, etc. etc.. scenes perfectly identical in all respects):

- render times are significantly reduced in 3DS Max, from 95 seconds to 72 seconds ... Corona in 3DS Max is 25% (and more) faster than C4D.
- the rendering of shadows and lights is totally different, in 3DS Max the light bounces are much more calibrated and even inside the rooms a completely better light reaches.

Can anyone explain to me why this is all happening?

I had fun recreating this room trying to give that attention to the light and the caustics of the materials.
It's been a while since my last posting, I'll start posting my scenes more often and in the meantime I hope you like it!

[C4D] I need help! / Re: Win10/Win 11 Lag
« on: 2023-04-13, 11:51:51 »
https://forum.corona-renderer.com/index.php?topic=39793.0 .. Are you by any chance experiencing the same problems as us?

i've the asus rog strix x670e with the last bios, ryzen 7950x, ddr5 5600, hd nvme pcie 4.0, win11 with the last upgrade

71
i've the same problem.
I also noticed that if you activate the caustics, the render times grow exponentially even by X10 despite activating the "Apply caustics only on these objects" parameter and not the whole scene.
My workstation is a 7950X with DDR5 5600mhz and HD Nvme pcie4.0.

[C4D] Feature Requests / OSL SHADER...long time waiting
« on: 2023-03-25, 13:21:33 »
When will corona's native slot for inserting parallax OSL maps be available?
It's been many months/years since has been requested... feedback or news???

73
what process did you use for the water? I just can't get a good effect between normal, caustic and volumetric to recreate that little rough water effect but also those horizontal "lines" like it's a slight movement of waves

74
i love you, spectacular! how do you solve the problem of subdivisions of floors so large in c4d that has the limit of 1000 subdivisions highlighting?! With a close view the displacement of the sand as well as the creation of dunes and details becomes a problem, right? As for the endless repetition of the material of the sand and the sea (procedural or..)?

tnx tnx

75
thank you very much, but unfortunately hot4d doesn't work with infinite plan. With a cloner and a sufficiently large surface (30x30 cloner of a 4000cm plane), even my 7950x with 128gb of ram struggles..
leaving aside the fact that the sea does not even come close to the horizon, 200 million primitives are created as a starting point.
