Nah, no one is chocking no one - it's still a free choice. Just 'the gap keeps getting wider'.
And know, this C4D 'streamlining' has been in works for over a decade now (from abandonment of modules, via transitory packages into "Maxon One" 'singularity'). Also, Maxon would probably be dismantled, if there weren't for the "Nemetschek group". Landscape changed, and every 'dinosaur' still consumes a whole lot, but must also evolve, ever since the 'global "http" impact'... and lately with all the little ai, ai, ai... :)

PS
Corona should really consider making 'standalone'. Tho, 'papa' is long gone now... rip.

Has wood/natural/organic fiber shader deriving from this been considered?
Looking forward for C4D preview...

for such cases, it might be helpful to familiarize w/ 'gray card', 'neutral gray photography' and of course, use of light meter...

example articles:
"Using a Gray Card for Photography: What is It & Do I Need One? by Jen Golay"
and

FYI,
I pointed out what needs to be done, strictly in technical terms! 
In scene attached, there's just a path pointing to HDRI map... 
go figure.

Have a nice day.

Right, while you mention some good points but all that doesn't solve this issue. Most corona or archviz users achieve this effect only in cases the blocking geometries / sun are out of the camera that's why it becomes harder for you to solve I guess, because focusing the light on a specific area in a cloudy day or like the PSA reference I showed doesn't need a photo reference! I guess I should explore some other approaches!

As noted, there's basically nothing to solve in the scene you attached (no HDRI map, lack of proper direction)... The way stuff is set,  in hope to achieve the same feel as the reference is simply irrational, which demands to be 'solved' with an illusion, just like in the movies. When natural reality doesn't work, you create your own. Nothing to do with an engine.
Try to provide HDRI and either sketch a concept, lighting plan or find better reference that resembles your 'vision' more (is more inline with what your 'architecture' demands).

Oh, your reference and stage set are totally different things. Indeed, sun's position and eye/camera's orientation play major roles in 'feel' of the picture. I rather consider thinking photographically. Found it better having more suitable reference(s) or even coming up w/ a mood board than going at it 'blindly'.
As for shadow, any light-interaction starts sharp. It is 'roughness' (medium scattering&density) that visually 'breaks' that rule and creates appearance of soft gradient falloff. As such, 'chiaroscuro' effect can be achieved w/ Cycles (or any other engine). It just takes slightly different shading approach, balancing based on its specs. That's roughly what's about - paying attention to noise - surface detail, which in your case is amiss.

It can be done quite closely to what can be achieved w "Physical Sky & Atmosphere"... but first would be nice to see what your current result looks like.
Here's a quick test w/ latest daily.
 

Edit:
Added "Volume effect"

[C4D] I need help! / Re: Fur-object/generator and corona hair material

« on: 2025-07-31, 14:16:49 »

Yes, it does.

If you didn't already know, It is possible to render Cinema 4D's hair with Corona Renderer. By default, Cinema's standard hair material is supported by Corona and it can be used to fine-tune the final look you are going for, i.e.: hair, fur, or grass. Cinema 4D's hair material is a post-process material, It's applied at the time of render and gives the illusion of geometry.

Maybe
- unlock sampling pattern, change frame#
- set "Light samples multiplier" higher (4)

[C4D] I need help! / Re: Pure White Background with Shadows

« on: 2025-07-26, 10:34:42 »

Hi, few things first, to eliminate any further confusion, have you checked:
- Infinite floor/background look? (HDRI Studio Rig look)
- Rendering out with alpha channel that catches the shadow detail
if so, could you then setup a simple exemplary scene and post it here to see what the reality of the issue is (and fix it).
 
&
BTW, this old setup (Re: Shadowcatcher artefacts) appears fine on my side.

PS
It could be Tone mapping, preventing pure white...

[C4D] General Discussion / Re: Is HDRI Lighting Generally Noisier?

« on: 2025-07-24, 11:31:04 »

Hmm, could also be that specific HDRI map. IME, some can be quite 'wicked' and need a bit of TLC. Also IIRC, some years back there were few such issues... w/ extensive noise using HDRIs in Corona Sky... need to check forums...
