Can you send in the scene via private uploader?

Which is pretty much what Corona does - there's a render element for it too, the SamplingFocus, where white shows where Corona is focusing most of its processing (areas with noise) and black where it doesn't need to spend so much time calculating.

Denoising came to be simply to reduce how many passes you have to do in order to get a clean image :)

That's it - I am going to do it! I am going to become a coder, I used to know BASIC programming, how much harder can this be? And I am going to learn all about Light Transport and the physics and equations of it all! I am thinking by Corona 30 I should be ready to set to work on this caustics problem! Look out world... which reminds me, I can start with a "Hello world" program to get ready for it all!

Examples of the materials that you feel don't convert correctly would be very helpful - preferably in a scene file but screengrabs of the material UI would do in a pinch, with renders showing the Legacy and Physical results. Thanks!

Might be worth sending in the scene :)

Ok got it now, I think! So the opacity of the wave object is being controlled by distance to the "weird shape" object, and where the wave object intersects the square, the wave object opacity of 0 is affecting the green glass of the square, making it invisible. Coplanar faces is my first thought, that the wave object top face is completely in line with the green square top face, thus the engine does not know which material to render and if it renders the wave object, you get this result.

Could also test by just having the wave object with a solid opacity of 0 - it won't render as desired of course, but would isolate whether this is anything to do with the Distance map, or just to do with the opacity of intersecting objects.

Quick solution, just don't have the wave object intersecting the square object at all (slice off the geo of the wave object). Meantime, to explore more, the scene would be helpful, if it turns out that faces are not coplanar :) Thanks!

"The clear coat example with the wooden table where it just says 'Combined' in the bottom right"

For the table, all we did is pass the two bump maps through a Mix and feed the result into the Clearcoat bump, thus making it a blend of the two bumps.

At a guess, it's expected - what object is the Distance From set to? I am thinking that distance is different in the reflection in some way. Also not sure why Corona Distance is used here, as that "boolean" object should always be invisible, so you could just set it not to render, or at least paint it with regular opacity without mapping such that it is always completely invisible?

"you would think Tom would have fixed the caustics by now after 3 more whole version numbers of corona render!"

I am not a developer - there's no way I can fix anything in the code, even a simple typo in a parameter name :)

Oh wait, ARCHICAD - well, it's no longer supported, sorry, there's no development or support for Corona for ARCHICAD any more.

What is Corona A5? Also, linear workflow is just the default, but I am not 100% sure what you mean - can you describe the process once you go beyond the render, so we know what you are trying to achieve? Thanks!

[C4D] General Discussion / Re: Corona for C4D You Tube
« on: 2021-08-31, 14:45:25 »
We do create C4D tutorials, but it's been hard to have the manpower to create tutorials for either version lately, sorry. For example, this time we focused on the Webinar rather than tutorials. We have tutorials planned for the new Corona 7 features, now that the webinar is done, with both Max and C4D tutorials being developed at the same time. Then if time allows, there is some catching up to do on Corona 6 features for both :)

Denoising uses the CPU at true 100%, so if you get crashes it means that something is overheating or otherwise not stable when the CPU is running at 100% for an extended period. Unfortunately this means that your overclock is not actually stable, in that case, sorry.

[C4D] I need help! / Re: Turbulance FD in Corona
« on: 2021-08-31, 14:37:07 »
It's not compatible at the moment, sorry (there may be some workarounds by converting to geometry or something, but I am not sure as I have never used Turbulence yet, since it is not currently compatible...). There is plan for particles support in 8 though, if all goes well

My understanding is they will be automatically fixed at render time in the data set up for rendering in memory, but not fixed in the scene - this will result in this same warning every time you render, so following the manual fix is how to fix it permanently in the scene and avoid seeing the warning again.

By renaming the LightSelect to "Right" rather than "R", it started working when saved :) For some reason, the name "R" seems to be protected in some way, as LightSelect with that name is not saved (once I had the problem one renamed to "Right", I renamed the "L" to "R", and guess what, it no longer showed up in the saved CXR).
