I see. Glad to not have to deal with those new colour management stuff. Will stay with gamma workflow as long as possible.

Reload the texture you are using for your normals, but in the 3ds Max "Select Bitmap" dialog click on the "data image" button and only then open it. This will load the texture in "raw" mode and it should appear correctly, with no brightness variations.

Are you saying that pressing data image button is not the same as manually overriding gamma to 1.0?

Did you try to reduce blending radius? I find that often very small values like 0,01-0,05 gives much better result.

Corona does not have outline render element. If you think this would be a useful feature, you can request it here: https://chaoscorona.ideas.aha.io/ideas

If surface is coated with opaque layer of paint or varnish, the material should be treated as non-metallic. It doesn't matter what's underneath it, as far as we aware there could be anything, or even nothing at all, generally it doesn't impact top surface properties.

I never liked highlight clamping, but maybe i need to give it another chance someday.

WOOW the change is indeed huge, do you have the render times for those ?

About 3 minutes for each, it was set to pass limit as stopping condition. I didn't look at noise percentage, but MSI 0 was obviously much noisier before denoiser. One would need to make more in-depth tests before drawing any conclusions, but as Aram said, with the new fireflies filter you can now play with MSI. Just a reminder - you want to increase it to make its effect less destructive. Setting it to 0 is a special case, i.e. MSI is effectively turned off, which is not recommended.

Not necessarily, you can use aperture for DOF and shutter speed for motion blur and at the same time still use simple exposure to control exposure. Corona is very flexible about that and doesn't force you into single workflow.

I never use photographic exposure. Simple exposure does exactly the same job and it's much easier to control with a single parameter. By the way, if you want to learn more about Corona tone mapping operators, then do visit its documentation page here: https://docs.chaos.com/display/CRC4D/Tone+Mapping+Operators

Your order of operators are all over the place. You're comparing simple exposure before LUT vs photographic exposure after LUT Of course you will get different result (incorrect in case of photographic). And as a rule of thumb, almost all operators should be above ACES OT. It doesn't make difference in your specific case, because ACE OT is turned off, but you always should try to maintain correct order, unless you really know what you're doing.

Speaking about bias, how about MSI? I was quite shocked another day to find how much light it could prevent to reach the areas that doesn't even seem that much occluded. Attached are comparison of default MSI 20 vs MSI 0 (off). Of course i would not recommend to turn MSI off in your scenes, because you'll surely get a ton of fireflies and much longer render times, but it might be useful to try adjust it in some darker interiors and see if you like what you see. Does anyone remember the old MSI 200 rule? :]

By the way, new firefly filter does pretty amazing job at removing excessive fireflies caused by turned off MSI (see the last attached example).

Not all materials are created equally, some are simple and will work fine in any scenario, others are more complex and might require some tweaking to work best in specific scenes. If you think there's an issue with some Cosmos material, it is best to contact the support team and share your concerns with them https://support.chaos.com/hc/en-us/requests/
