[C4D] Daily Builds / Re: 100% cpu in IPR usage in daily?

IME, such issues can be/are prevented using special OS 'cloning/backup' tools...
(ie. "Reflect"; personal preference, since they had free, unlimited time version, 'till not so long ago.)

I too found this strange occurrence with latest Corona plugin.
User set core/thread count is respected, but only when using Cinema's "Interactive render region" (Alt+R), all else uses all cores/threads.
Wouldn't had noticed, since I got single core reserved. After changing that to half, it got obvious.

FYI
Check this one out, if you haven't yet: "Siggraph 2015 Rewind - Bret Bays: Creating a Character Rigging Pipeline in Cinema 4D"
Decade old, but still holds value ~ not much has changed in this area... :\

The thing about "Highlight clamping" is that it clamps light contribution all over. So other parameters need to be balanced accordingly. It ain't magical solution.  Tho, from looks of it I suspect you got issues elsewhere... HDRI, highly reflective surfaces, caustics,... unreal values?

couple of tips:
- Keep it as close to physically accurate as possible.
- Learn  about 'Light painting' and 'multi-exposure' techniques commonly used in photography.

Also, get to know "Highlight clamping".

Unsure, but I believe 'Denoised' one uses different 'layer/pass' (under the hood). How would otherwise be possible to set value in post? IDK ;) ... In this regard, I'd love to see "DENOISED" in Multi-Pass.

BTW, you can "Gather data for later" (Denoise on demand after).

[C4D] I need help! / Re: Animated light gel materials
« on: 2025-01-08, 17:52:00 »
Yes.
- Works with standard "Spot Light" and "Material" (Color/Luminance +Transparency channel; dark otherwise).
- Can take standard video formats (supported).
- Doesn't show in Corona's "Interactive View", but in standard "Interactive Render Region (Alt+R) it does.

Alternatively, you can simply use emissive decals ("Light Material"). 

Have fun.

PS
Using 'gel' also works, but is blurry and bit more noisy.

Hardware / Re: Color space/mode

Nothing to stress about. OCIO main role is in VFX production (compositing). Where there's non-standard (un-Linear workflow - many different Camera Inputs & specific Display Outputs, with diverse artists/studio sets in between). Using it, user basically 'describes how elements/components talk to each other' with intention to keep (digital) 'Colour' consistency throughout whole pipeline/framework, making production more effective and cheaper.

Simply keep your LWF, know your white point value, let compositors master their stuff. And in this regard, best you can do is to provide/supply clean HDRIs. Unless requested otherwise, off course.

TL;DR
It's alike taking care of how HDRI color is mapped to 8bpc displays (sRGB) and/or prints, but in cinema/film industry

 
BTW:
Quote
Since "color space" identifies a particular combination of the color model and the mapping function, the word is often used informally to identify a color model. However, even though identifying a color space automatically identifies the associated color model, this usage is incorrect in a strict sense. For example, although several specific color spaces are based on the RGB color model, there is no such thing as the singular RGB color space.

Going back to the original topic, I spoke with someone from Blackmagic’s customer support, and he admitted the problem. He also noticed the difference in colors and contrast between the Color and Fusion pages on the Mac version.

Nice to know :)
Care to link threads...

Disclaimer:  I'm no photography pro and I far from have a deep technical understanding of it but ...

Surely you want your exposure to remain in the stack at a bare minimum.  Just like if taking a photo but plan on editing it in raw, you still expose the photo first and that's your starting point right?

It's something that always confuses me haha.  Especially that AcesOT +1 stop of exposure thing.

I'd love someone to point me in the direction of a tutorial where someone takes a linear render and tonemaps it in Fusion/Resolve (ideally Fusion) and gets it back looking similar to how it did in the Frame Buffer before disabling the stack.

The way I see it, if editing the linear untonemapped image is akin to editing a raw photo, then the frame buffer is akin to the screen on the back of your camera.  Its giving you a preview of the tonemapped raw render/photo.  You then take that render/photo into your editor of choice (fusion/lightroom etc) and tonemap it using the flexibility of the tools in that editor.  But my point is - your raw photo still relies on the exposure you set when taking the photo right?  I appreciate the idea of RAW is that you can alter whatever you want after the fact, but you still want as close to a correctly exposed starting point as possible right?

What am I missing?  I want to be educated .... hit me with it
Basics of HDR?

There's really no 'consumer' digital camera with HDRI sensor available. Last I checked, 14bpc was max. (?)
RAW is just standardized industry image capturing format but still 'lossy' (minimally processed) in this regard.
To create HDRI with consumer camera, multiple exposed shots need to be combined into single image.

Virtually, Corona engine processes light transporting simulation in parallel universes, either w/ Adobe RGB or ACES color space and depth of 32bpc. (Results highly depend on 'Creators' input).

So, to express intent, display 'vision' or just tele-vise idea, adapting all gathered information/data that is considered influential to another being's experience, using certain medium to best of abilities is must (Know thy tech/industry). Then, depending on capital/budget, results are cut, clamped and filtered down for 'big, lovely eyes' attention and consumption, to 8-12 bpc :) 
Here's where "Tone Mapping Operators" (docs) come to help.


Personally I use many different ones, depending on style I'm after and mood I'm in. Keeping it linear as much as possible and 'till the end is my preferred way. As for some shit and giggles comparison, IMhO, human vision's dynamic range surpasses 160bpc. Depending on food, mood, age, skill, tear and ware... But note that ALL OF THIS HERE is just discrete 'digital-shit' measure, excerpt from 'vision of reality' in an infinite analog spectrum. Avoid distractions. Fix ADHD w/ OCD. :P

Don't get confused. Disabling whole stack simply avoids any manipulation/contamination.
