Hey Folks, I made a tutorial on how you can do this with the current build of Corona in C4D.

Thanks!

[C4D] Feature Requests / Re: Basic X-Particles Support
« on: 2018-10-28, 18:20:28 »

Anybody have any updates on this? We really just need the ability to render splines as hair and particles at render time. Would love to know if this will be possible in the near future.

[C4D] Feature Requests / Basic X-Particles Support

Will Corona be getting some sort of basic x-particles support? Every other major render engine on the market supports x-particles in some way or another...

I'm afraid I won't be able to use Corona commercially without some x-particles support.

Thanks guys!!!

Camera mapping front and back does not work correctly. Camera mapping in IR also does not work in all of my tests.

- Shawn




Camera Mapping is not working in IR. Also front and back options are not working in render to Picture viewer.

- Shawn

There are also important to me, I checked these... Camera Mapping working in IR. Texture sides also working in IR...!

I have the new threadripper 2 32 core and it's been great does run a little hot but nothing that can't be tamed with a good cooler.

Congrats guys! New Layer Node is awesome!!! Thank you!

Hey Corona team can you please add the ability to add Corona "Standard Material" to a hair object? Right now you can only add Corona "hair material" and we need the ability to C4Ds amazing hair for other things than hair...

Thanks so much!

[Max] Resolved Feature Requests / Fisheye Lens >>>
« on: 2018-09-26, 19:16:14 »

Hello Corona folks / development team :)

Can a fish-eye lens be added to Corona's camera? I do planetarium work for NASA and would love to be able to use Corona for all of the work we are doing. Unfortunately the final format has to be a 180 degree fish-eye render.

The only engines I can use for this correctly in C4D are Arnold, Redshift, Vray.

I would absolutely love to use Corona on these projects.

Attached are a couple images for reference of what I need to be able to achieve.

Thanks so much!!

I'm getting instant crashes with proxies in the latest build...

Hey guys UI bug with R20 and materials... See attachment...

Thanks!

Is there a trick to getting Corona Proxy's to work in C4D? Never been able to... "Loading failed due to memory error" every time.

I have tried Vue and Ozone for Cinema 4D, fortunately those tools are extremely slow and I don't even think they're in development anymore...

it's not that I can't get awesome results with Cinema 4D and Arnold I just want that functionality in Corona :)

I make all of these computer-generated HDRI Maps with terragen... http://shawnastrom.com/cghdri/

Still very slow to render though some of them took over 80 hours on a 40 core server with a Cinebench score of 4900 at 16,000x8,000 resolution.

Thanks for the tips on the image not quite finished working on it but I think I will definitely reevaluate a few things.

A lot of my comments boil down to hoping to one day have just one engine that I can use for all types of 3D imagery instead of having to switch around between multiple render engines for specific needs...

- Shawn


Ok, one last thing.
Have you tried Ozone for C4D/Vue Xstream?

You can make very nice clouds in there. The image still has to be composed but it should work faster than Arnold.

A support for the native cloud tool(or full Phys. sky) would be great, together with the option of adding CRN materials to add high-frequency details.

You could also try Navie Effex. It's for free now and you can load open VDBs and use them with AR.

Well, that's all about clouds and C4D.

edit: I just read that Furryball for Max, Maya, and C4D is for free now. Since Furryball supports pretty much all of the Arnold shaders, you could try and render the clouds with that.


edit2: one more critique. ;-)
What time of day is shown in your image? Clean clouds, especially in the morning have a well visible pink tint.

I often look at the sky, so the reverse engineered UFOs from the USAF that were shot down in Antarctica can't catch me.
Bob Lazar is still working for the government, he's lying to us!

Definitely appreciate all the comments and thoughts. I was also using Houdini for a couple years in production but I found the workflow extremely slow. While it is an exceedingly powerful piece of software, 90% of the time I don't require procedural workflow for everything...

Also after using Cinema 4D for over 12 years it's difficult for me to switch to other applications especially being more of an artist and less of a technical user...

I have managed to get some extremely awesome looking clouds using Cinema 4D s noises and Arnold. I'm quite happy with all the tools I have at my disposal but I'm really pushing for Corona to have some of these missing features that are more or less in the max version...

I do appreciate the artistic comments I'm still working on this particular piece of art and while there is volumetric atmosphere and of thin Cloud layer they're not very apparent I may need to tweak the settings further.

With all my experience and other render engines Corona is by far the easiest to set up and looks the best in my opinion. I'm sure technically you could get all of these engines to match extremely closely but for some reason in Corona it just is easier to do...

Anyhow can't wait for the next beta update!

- Shawn






Well, ok. I see no other way than compositing the image from different renderers. After all, they do it in movies too.
Baking doesn't make sense if you need a procedural 3D noise.

What I would recommend is to try Houdini. There you can create such things with ease using a non-destructive workflow. It has many presets, free stuff to download and almost everything has OpenCL support. It actually could make most C4D plugins obsolete. Terrain with erosion, vegetation, vdb modeling, fluids, liquids etc. etc.
The built-in Mantra & Renderman engines are quite fast drawing the media, but since you have Redshift, you could install it without any additional price iirc. You'll have more than enough noises for clouds ;-)

The Basic Non-Commercial version is for free,
the other two types depending on how much you make per year, but still, they're within a very reasonable price range.


PS: about your image, forgive me if I'm bothering, it's just one of my pet peeves... Large-scale scenes.
You should add a subtle volume to the scene to fake Rayleigh-Scatter. Also, a second flat, soft cloud layer wouldn't be wrong if it's not overdone. There you wouldn't need fancy scattering.
I also think that a small amount of a multiplied noise layer for the terrain, but also the water, to create a bit more variation could do wonders.
