I did notice an effect with ACES that I rather liked. But with photographic exposure it does not work. So I will stick to simple exposure for now until I get a word from the Chaos Corona team on what I am doing wrong.

You can read more about ACES here:
https://garagefarm.net/blog/what-is-color-space-and-why-you-should-use-aces

In short, ACES (Academy Color Encoding System) is a free, open, device-independent color management system that standardizes color space between different input sources. Using ACES results in more photorealistic renders due to its wider dynamic range and ultra-wide color gamut. Additionally, it provides a wider array of colors to choose from, making it a more future-proof option within production pipelines.
For digital artists, the biggest reason to use ACES is that renders look and feel more “photorealistic”. That’s because of the wider dynamic range.

Thanks BigAI3D
Just found out, it's the ACES OT that has to be turned off other wise photographic settings won't work (properly).
ACES OT works well with Simple Exposure though.

Not sure if this is a bug or normal behaviour.

Intensities are just at 1 as they are set at default.
There is something wrong with the latest release I am afraid. Or just on the Mac version.

I added the photographic exposure to the CR camera tag and then at render it does not disappear from the settings in the VFB. But the render comes out black or very faint. So there is something not right here.

I always use the simple exposure so I am not stuck.

Thanks, Beanzvision,
I simply can not render a photographic exposure, see attachment. As soon as I start a render the photographic exposure setting disappears in the vfb.  This is probably a bug in the latest 11 or I should go home and try this again after a good night sleep....

Hi,
CR11
OSX Sonoma
Mac Studio Ultra

I am trying to understand and set photographic settings but somehow it does not have any significant effect. And so I always use simple exposure.

It looks like there are 3 separate locations for setting photographic settings, at corona camera level, at the VFB, and at the Camera/Postprocessing at the render settings. I have no clue in what way they override each other and also never see any effect on the image changing photographic settings at any of the locations. Why not simplify this and keep photographic settings only at camera level and make it work. I have never been able to reproduce a simple exposure of -5 for an exterior render by setting a photographic. Is it a bug or me with a lack of complicated knowhow that keeps me using simple exposure.

The asset browser work great but I have to many assets that are not working properly. Especially with layered and CR bitmaps.
I have set up files with assets that belong together and just copy paste them in my working files.
Another thing with the asset browser is that it duplicates all CR materials. For instance, many different maxtree assets can share the same 2 or 3 materials but when placed with the asset browser all assets have their own materials.

Thanks CambridgeCreativ
The node editor is handy at times and I do use it. Mostly to use a single map for several materials. Still, I have no idea why I should worry about wether it is a CR bitmap or just a dragged a dropped map from the finder.

The asset browser does not accept CR bitmaps btw. Although I am no longer using the asset browser because of the many problems with CR assets and their materials.

See that in today's release 11 this problem has been solved. Thanks.

I still see some materials of Maxtree's vegetation that need attention especially in the IOR settings. Some have opacity maps or values of 1 or 1.2

Interesting. I do wonder what the difference is to make up for the huge hassle to set maps that cumbersome way. I have never done that and have also never seen any difference. Although I don't care much for render speed if its a minor difference.

Not sure if that's right about the Corona bitmaps. Does the converter does not do this automatically. I have actually never set a texture (bitmap) like that. I just drag and drop textures from a folder into a CRmaterial. You can even drag and drop maps from for instance diffuse to glossiness. You can even drag and drop in to several selected materials at once.

Am I right to see that noise distribution is per surface and not per square setting ?

13
Thanks,
That must be it then since I usually work with cubic mappings. Will try to stick to UV for now.

I scatter now single leaves of grass instread of clumps. Graswald provides excellent assets for that. Like this I no longer need to edge-trim.
Not sure if this is specific for Coronarender but I love to edit sets of Corona materials and Chaos Scatters by selecting them all and edit without the need to edit them separately. I tried Redshift but it seems a hassle compared to Corona.
Corona scatter truly makes a big difference. I hope it's going feature gradiant dimming closer to the edges of a surface. Generating vegetation is so much better than placing assets with a mouse. For Blender Graswald provides assets with preset scatter settings and sells them as easily editable environments. Pity Blender is to slow for Archviz at any larger scale.

RC3
OSX

Problem seems to have gone. At times settings noise patterns does not make a difference although maybe just a matter of doing a restart.
RC3 seems to be a rather solid release. I haven't had a crash all afternoon doing a lot of scatter work with IR on. It's so nice to be able to play with the scattered densities.

Thanks Bengamin
Chaos Cosmos is a great resource for Corona users like me.
