Rendering with Corona

[maru]

To reduce those fireflies in the background/out of focus:
1. Use the improved DOF highlights solver - https://support.chaos.com/hc/en-us/articles/4528608272785-How-to-enable-and-control-Depth-of-Field-DOF-in-Corona-for-3ds-Max#h_01H3208VDBVX29VA2HACX56B2V
2. Set highlight clamping to as low value as you can without making the image look bad (but higher than 0) - https://support.chaos.com/hc/en-us/articles/4528471000849-What-is-highlight-clamping-3ds-Max

Hi,

thanks once again for your support!

I already followed your advice, the first pic shows the highlight solver enabled, and clamping set to 1, 56 passes.
For the second render I increased the budget value(whatever that is?) to 8 in the solver,and reduced the clamping to 0.5, with 27 passes.

The second pic looks darker, with less details, but both are free of fireflies and much annoying highlights, at least in my opinion.

Good to know, so thanks again fpr your help!

Always glad to help!

The DOF highlight solver improves the quality of bright "bokeh" spots.
Highlight clamping will always make images darker because it, well, clamps highlights. :)

One note: when using highlight clamping above 0, the output is not "high dynamic range" any more. So if you are planning to do some compositing or need a wide tonal range for other reasons, don't use it.

Hi,

in some further exploration of Corona I used a quick setup with only a couple a lights, no sky, no sun.
Instead of limiting time or the amount of passes, I used the noise level.
In pic one it was set to 4 wirh like 40 passes in 7 Minutes rendertime. the second one saw a reduced level set to 3 ,
with some 75 render passes and rendertime doubled.. After a first quick look, i could not see a noticable difference.

HI,

I had the opportunity to play around with a newer version of C4D wirh the particle system, but at least for now i didn´t found the excitement as expected.
Maybe Particles stuff comes a couple of years too late for me, i`m prefering  soft body/cloth stuff nowadays

Even though I have not the slightest idea how a piece of software like Corona works, I would like to see a Corona Tag for particles, similar to the spline tag(no circle, no sweep)  because simulation of a lot a particles inside a cloner with gazillions of tiný spheres means an awful slow simulation.

If there is an imaginary wishlist, I would like to see a foam render tag(I already brought this up a while ago, and some more fancy materials inside of Corona like Styrofoam in a future version of Corona.

Hi,

a new round of try and error, this time a little bit from the dark side.
I also tried some volumetric lightning, but ended up as usual with heavy banding,

You can always go to Corona ideas portal and submit your requests there: https://chaoscorona.ideas.aha.io/ and also vote for already submitted ideas that you like to be implemented first.

Hi,

a couple more pictures with some particles and the "magnificent" Spline Tag, which
makes the live a lot more easier, at least inside of Cinema 4D.

Hi,

I found some inspiration on this site(Chair file) and on the Net, to work on an "advanced" Lightning- Set Up,
with mulltiple lights, partly very large, very close, and with low or high intensity.

It is easy to lose control over each lightning source, but in the end, it looked kind of cool!

[Torsten Angerer]

Hi,
today I like to upload two more pictures with sky only lightning, which i prefer,
because it is much easier to handle than any other setting.

There is no color correction,

Hi,
I found some time, and had the patience to upload a new animation on YT.

All rendered in Corona with Sunlight only, sometimes with the support of a tiny auxiliary light in the background.

I uploaded some more pics on my starving Behance account, but somehow my  content is hard to find.

That was a rather fun watch, ty for sharing!

Hi,

searching for some new interesting stuff, I like to take a closer look into "worn edges", curved decals and maybe light gobos!
