It would be a dream come true if I could control the density of a volume with C4D noises in Corona.

Did you try to apply a noise texture? When I apply a noise, it works as intended a you can modify the scales and select your shader.


That being said, I can't find the way to create a cloud out of this corona volume texture. I can only place the volume material inside a solid but we can see the edges of the solid. For instance, is there a way to create a fall off to the Corona volume material?
I tried everything:
- I placed the volume material in a layered material, then created a gradient with a 3d spherical projection: does not work.
- I created a Mask material with a 3d spherical projection, I applied this material to my solid along the volume material: the materials don't work together.
- In the volume material texture itself, I clicked noise, then Layer, then I applied a gradient layer above the noise texture. The gradiented noise is successfully applied, but unfortunately I can't find the right 3d projection (I tried all of them).

Hello friends.
I wanted to know if we can already have this type of hair finish with Corona?

All achievable by tweaking the hair settings ;)

this is why I commented about having this support it because it is currently not. In the new Corona core it is supported but I believe this functionality has not been exposed yet in the Cinema 4D plugin.

I'm not too worried about openvdb support yet but if we could control the density of a volume using Cinema 4Ds 3D noises that would really be helpful for a project I'm currently working on. in theory now that this is in fact a supported in the latest version of Corona I would imagine it could be set up relatively easily in the C4D plugin. But then again I'm an artist not a developer and code is beyond my puny brain...

Hello,  beanzvision
 it would be nice to have the hair parameters you used
for your carpet.
Can you share them?

Sure thing, I'll need to find them. Once I do I'll share the scene.

Yes, please share it.

After my involvement in Project Blue Beam, the CIAMossad is making my life hard. The so-called holograms are actually real people who were phase shifted like LaForge and Ensign Ro in one of the episodes of Star Trek - TNG where the Romulans tried out some new technology to move their ships through matter, similar to Project Pegasus in a later Episode where the Federation tried to replicate a cloaking device and gotten that as a result.
Riker was involved in that too, but this time he was on Picard's side.
The Illuminati Lamp People used one of Elon Musks Mental-RayNvidia's Jensen Huang's I-Ray satellites to wipe the memory of NOTHING SPECIAL.
But I shaved my head, so the Melanin in the hair cannot function as an antenna amplifier. (I think that feature is missing in the hair shader)
However, the CIA NWO spooksfriendly agents for information retrieval also INVITED me out TO A NICE CAFÉ and I am VERY PLEASED.
Anyway, since I'm bald now, the Satanists Jehova's witnesses switched to spraying Chemtrails over my house or general area, not sure. The airport is not that far away and I see lots of planes. I fear that they're going to use the planes to drop needles filled with Vaccines to give me Autism and thus forcing me to use SketchUp PRO.
I also suspect that some of the dogs in the neighborhood are watching me. I've sent a bag of fecal matter to a laboratory to find out if the dogs were part of a Dog MK Ultra programschool, which one can find out by measuring the sodium levels.
However, I dunno, so I lay out poisoned sausages on the streetcandy. Where are the PETA animal death campsis a Volvo when you need one?

Better safe than sorry my mother always says.

PS: Don't forget to take out the batteries of your phones and insert them back upside-down, so the antichristMessiah Jules Urbach can't leave a mark on you and it'll save you from hellblesses your projects and increases CPU raytracing by 66,7%.

Here's a "little" Scene I'm working on. This is a perfect example of needing volume density control for clouds :) These clouds are modeled meshes with displacement.

Also, Arnold is killing me with render times on another project. All I need to never use Arnold again is... Full Volumetric support, Fisheye camera, basic X-particles support :)

Thanks guys Corona is the best!!!

Do you use Arnold to render the whole image ??
I can give you an idea, I do not know if your project is animation or just an image.
If it is an image, you can do the following.
Render with Arnold only the clouds, in transparent background.
Use Corona for the whole landscape and in photoshop you place the rendered clouds.

You can use this trick while Corona develops render for particles

I've definitely done multi engine renders in the past even with animation. Just hoping for Corona to have these features soon so I can ditch Arnold and give my money to the Corona team!

Hi guys,

I have been quietly getting my head down and working tirelessly over the last year.  I had the pleasure to meet Nikola at SOAA Day #8 and since then, we have entirely converted to Corona from VrayforC4D. I am absolutely blown away by the commitment, the quality and the passion of the Corona team and what they are managing to achieve.  Corona is incredible and has given the whole studio a boost. both in terms of creativity and productivity!

So... after a year of testing, testing, testing, we have generated over 350 production images using corona. Along the way we have found a number of bugs, some technical challenges and few 'wish list' items that we would like to suggest. 

The list is quite long and some of the features may have been rectified in latest releases so apologies if that is the case.

We have been using each Beta daily build so I am aware that there have been many bug fixes.

So should I just add them all here to one post or is there a more 'formal' approach?

Although a couple I must mention now are in response to the latest daily build as I am experiencing issues that previously didn't exist:
    • Corona sun renders despite being turned off and both 'traffic lights' being red!
    • When using viewport render region, all standard materials suddenly get converted to corona materials and the render doesn't start.
    • The interactive renderer renders hidden objects
    • The shadow catcher is still affected by tone mapping, despite using 'corona tonemap control'


I'll post the rest if this is the appropriate place to do so?

Keep up the good work guys!

J

@Shawn

You could also use C4D's 3D cloud modeling tool (physical sky).
I doubt that there'll be much visible difference to the Arnold Volume. 3D noises work here too. Worst case would just need a little bit of post.

Arnold is still a great renderer, but unfortunately, it's designed to handle heavy TB sized scenes and therefore, a monster of a "computer" would be the best for that.
Arnold machine:


However, I'd say that if you need a biased renderer, go with Redshift. It has the familiar Arnold workflow and the speed is insane. My test scenes were easily 20x faster in Redshift, even though I used more bounces, a higher shading rate, and a much higher resolution. (BFBF on a GTX 1080)

For unbiased stuff with many bounces, you can still use Corona.

I rely heavily on C4Ds procedural shaders but I need them to work in Corona Volume material. I used both Redshift and Arnold in production for a couple years now...

GPU renderers lack of procedural shaders support is really unfortunate.

I'm just saying that once Corona has 3D Shader support in Volumes and a Fisheye lens I won't need to use Arnold anymore for a large series of project that I'm creating for NASA. oh and we also need basic x-particles support...
