Thank you for your answers! Is it useful to add ocio Vray renderer to environment variables?
VRAY_VFB_OCIO - no.
OCIO - yes, if you are using only/mostly one ocio config.

Hello, do you need to add OCIO configuration environment variables in the corona renderer?

no, just luts.
created with legacy gamma setup in 3dsMax 2024 in mind.

We're looking forward to seeing this implemented. Recently we have been using piotrus3333's LUTs setup to achieve this and have been getting great results, but it would be nice to have it as a "set and forget" option for the rest of the team.

If you like the feel of AgX please consider checking this:
https://github.com/sobotka/AgX-Resolve
this is THE AgX by Sobotka. ocio version is the simplified one. you should be able to create better luts from this. it's based on arrilogC3 encoding so I guess as a bonus (if porting to Corona) you get an easy access to all the arri's looks library.

Corona does have a view transform. you just can not change it or turn it off. 3dsmax gives you the option to apply it, not to apply it or even apply a different one when it asks you what gamma would you like to save your output with.

correction: you can actually turn it off without affecting 3ds Max settings with string option: float colormap.additionalGamma = -1.2

Hi all, thank you for your feedback. We now have this logged as a feature request.

(Internal ID=1213995718)

Ok. this is sorted now. I guess no need to keep the request opened.
Thanks.

If I remember correctly Corona's subscription started from 20/month. I do not recall the version number but I'm sure you wouldn't trade current Corona for the old one to save 10/month. You are getting more than you used to get. You might not like the things you are getting (Cosmos) but the value is there. Check car prices in Europe from the year Corona introduced subscription model to get some ideas about things getting expensive.

Regarding the USP? It is simply not there for you anymore most likely. But also look around and, if possible, show us a better deal from Chaos' competitors.

With regards the 'Solo' option - this is the whole point, we would then lose render nodes and floating licence, so it becomes much more expensive than Premium if you want those features back ...

A lot of us indie's have more than one PC that we use for DR or with Pulze etc so the render nodes that we got as part of our monthly subs back in the day are essential.  Also, as an indie, by nature you can work from anywhere, it's great having Corona installed on your main PC, but then having a floating licence so you can also pick up your laptop and go work from wherever whenever.  You lose both of these things with Solo.  So you're forced to take the Premium option because it's cheaper than Solo + Render node + Render node etc, but then you're paying for premium and the price of premium includes Cosmos and all that Jazz. 

There's no middle ground.  We need a middle option for Floating Licence plus Render Nodes minus Cosmos, Phoenix etc etc.  Call it Solo Plus or whatever you want.

Floating licence - you are right - nice thing to have, so: you get some, you loose some. I would consider pricing from Chaos being quite reasonable considering its position within the market. Look at Redshift and Octane (bit cheaper) - priced in relation to Corona exactly the same as Corona is to VRay (VRay being 50% more expensive; sure, both are GPU but GPU is just the right choice for small operations for some years now - licences cost vs hardware scaling-up cost)

And be mindful that those legacy deals with 3 render nodes will not last forever. Nothing does. Just business, nothing personal.

I would suggest to take a step back for a moment (mid 2010's I guess if you value precision).
Archviz crowd fell in love with Corona exactly for the reason of it having less features than VRay. It was way more streamlined, focused on specific needs. Good product, good value.

A decade passed.
Everything has evolved and improved: Vray, Corona. Even 3dsMax. VRay Premium yearly sub with more features is 50% more expensive than Corona's. I would say: a good deal. Quite Fair.
If you do not need all the Premium "gimmicks" but would happily enjoy some of VRay's features: VRay Solo being priced exactly as Corona Premium might be the option for you. Again: fair deal.

Please accept some facts before complaining:
+ VRay is the flagship product and it will always get more attention: you are paying less for less. Fair deal.
+ Corona would have never got to its current state if it stayed independent. It would be a few years behind. Because of the support from Chaos the development progress is still there, it is naturally slower now, as was stated here many times: all the easy features had been already implemented and new stuff takes more and more resources, not less.
+ You are a consumer, last decade spoiled you with so many choices: if you're not content with something - shop around. Vote with your wallet as this is pretty much the only vote you have in the free market.
+ And the most important one: You as a user changed as well. Corona might have been the right choice for you in 2014 but in 2024 your needs are probably much different.

Wow I didnt imagine that Arnold was similar in terms on Speed, what about memory?

After a few tests I did over the weekend, 'speed' is certainly not how I would describe Arnold lol. Difference is night and day compared to Corona, Even rendering a simple box/teapot scene with GI on was terribly slow in Arnold both CPU/GPU. Painful to say the least.

It is quite hard to compare them. Very different engines. Corona might be faster with simple interior stills but get more complex scene, add animation and from the point where cached GI is no longer an option Arnold will show its strength. Memory wise its much more efficient.
There is also GPU option if you can make do with less features (less features make for much simpler render setup though).

Insightful read.
A suggestion, if I may: Arnold. You are already getting it with 3dsMax subscription. CPU focused like Corona. Similar speed. Much more features. Just give it a try, dip a toe.

Ive been doing this recently but i really really miss lightmix.

there is light mixer imager. what is missing from it?

still not a curve.
you can compare it to a very precise 3d lut.

https://docs.chaos.com/display/CRMAX/Tone+Mapping+Operators

Care to elaborate?

From the docs I see:
Applies approximate ACES Output Transform, which consists of Reference Rendering Transform (RRT) and Output Device Transform (ODT). Value range: from 0 to 1.

How is this different from a curve?

just click the links from the docs:
https://en.wikipedia.org/wiki/Academy_Color_Encoding_System#:~:text=in%20%22RRT%2BODT%22.-,Reference%20Rendering%20Transform%20(RRT),-%3A%20Converts%20the%20scene
and read. google if necessary.

y=x/(x+1) is a curve
y=x/(x+0.187)*1.035 is a curve
Hable's tone mapping formula from Uncharted 2 is also a curve.

and this is how code for ACES RRT apparently looks (source: FilmLight):

Can you share a link to the "official docs"?

All I found was this which was 2 sentences:
Note that highlights and color information in them is better mapped with ACES OT enabled and the overall image balance is better.
You may also need to adjust the exposure and tones after enabling ACES OT to compensate for them in some cases.

ACES OT is not just a tonemapper / curve.
if you do not trust the official docs have a look - this is bottom part of what ACES OT transform does:
