[C4D] Bug Reporting / Re: Corona Color Correct

IIRC, this one's ancient (also, when using Layers) - note, I haven't checked it in a long time.

Simple test/study scene file would fare way better

Reminds me how Sony contaminated/influenced music industry with its transistor and how digital tech revolutionized whole specter of production. After, new/alternative styles come to play. So, more power to creative souls and more 'beauty or shit' to throw around.

[C4D] I need help! / Re: Color Profile Issues with Cinema 4D R25 and Corona 12

Hi everyone,

Sorry for the delay in responding, but I’ve been doing quite a bit of testing.

I’m really struggling to achieve the results I’m aiming for and noticing a lot of discrepancies between how lights work in real life and how they behave in Corona. I’m sure this is partly due to my own lack of experience with 3D. I’ve worked on film sets for 15 years, so I know how to light a scene to get the results I want, but in Corona, I feel like a total beginner. I hope someone here can give me a hand—haha!

As for the pink/purple tint issue, I think I’ve managed to minimize it. However, I had to completely remove the background and rely on the VFB’s post-process settings. For now, the issue seems resolved, but I’m not confident I used the right approach—it might just be hidden for now and reappear when I change the lights or the set.

Another problem I’m facing now is the excessive reflection in the scene, which you can also see in the screenshot. This box (textured in Substance Painter, mainly because it’s easier for me to work with the PSD files from the graphic designer, which contain many masks and layers) is supposed to be made of paper, but paper doesn’t reflect light like this.

On top of that, I’m having trouble understanding how the “directionality” parameter for lights works. I’d like to create one light with sharper shadows and another with softer ones, but this parameter is confusing me. I can’t figure out which real-life property it’s supposed to emulate.

To summarize:

I think I’ve resolved the pink/purple issue for now.
I’m struggling with excessive reflections that alter the look of the scene.
The "directionality" parameter behaves in ways I don’t fully understand.


I’ve also attached my project file. Please don’t share the box design anywhere else, as it’s under a contract I signed,
Also, I can’t figure out how to share the project with the textures because every time I move it to another computer, it can’t find the textures. As I mentioned, I don’t have much experience with Cinema 4D, so I’m also attaching a zip file that includes them. (here's the texture, i don't have any other solution if not a wetransfer because they are too heavy https://we.tl/t-m5WO7Nrgfc )

Missed that, but anyways, previous post sums it pretty well.

It's always best to make and share a 'Study' scene file.

Fairly correct is still incorrect - especially in 'colour science'.

disregard

on 2nd thought, since I can't reproduce this,
does it also happen, if you disable tonne mapping altogether (in Camera & Render settings)?

Ok, another thing then, C4D specific.
Would you care to check, if it's same as this: "100% cpu in IPR usage in daily?"

Does it happen w/ VFB2 or Legacy or both?

Had previously noticed similar pattern and switched to Legacy VFB.
Latest v13 daily seems OK for time being.

Hardware / Re: Dual socket Epyc 128 cores AMD, and Threadripper 96 cores don´t work with corona

« on: 2024-10-31, 09:50:42 »

Personally I'd use other platforms/framework, but alternatively, you can consider making few 'virtual machines' (split workload) and that way use machine's full potential until issues get resolved.

Have you tried deleting C4D preferences?

//Note to debug:
1.) Make a backup.
2.a) If deletion resolves your issue, reconstruct former structure - add back directories one by one
/iterate large structures for faster solution, split stages in half, to see which one is causing issues.
2.b) If not, return to former state.
3.) Report back.

PS/Edit
Same goes for resolving plugin conflicts.

Edit2
Observe, check console for reports.

That's "Color checker" issue that needs fixing (adapting values manually, 'till some TLC from Maxon). While using properly prepared maps it's more than fine. (preferred ;)   
So here's corrected LWF-Linear render, where you can only observe slight difference in dark areas between EXR (HDRi) & JPG (LDRi) (but that's old Corona issue ~  and another topic :P

LWF choice depends on input maps/textures.
sRGB is correct in this case.Had messed test render results/names. Also, I mostly use HDR textures, thus uncertainty and confusion. Here's your scene redone anew with render results passed through Resolve.

OK. Have checked and observed you didn't fully disable Corona's Tonemapping and you also have Cinema's LWF set to sRGB, which are most likely source of your issues.
More you know, less you know... ;)

Yes, that was specific issue, but there are also other tips (and links) there, informing how to get consistent results, manage colour, grading, levels, ...  over different types of displays.

Either way, you can post your exemplary Resolve project here and we'll see how it fares on other systems.

Edit/
or just share your .exr, for starters
