[C4D] I need help! / Animation noise issue
« on: 2022-09-13, 00:08:42 »
Hi guys,

I've been trying everything but can't get rid of this noise when animating it.

It happens even if you leave the object static in the scene.

Any advice on that? I'm pretty sure I'm missing some settings here in order to get it smooth and clean.

Appreciate any help

Hi Guys,
Still not quite comfortable with physical materials, when trying to achieve some sort of translucent matte rubber material for instance, I can't achieve the same result as I get with legacy material. When you apply volumetrics scattering it messed up with roughness parameter. Maybe something should be reviewed in order to make it more accurate/intuitive.

One Scatter for the jellies, so far working good. Now, how can I apply the suggar to all of them?
Also, do I have to have one Subdivision to each mesh inside the scatter? Because if I put them inside a null the Scatter will scatter the whole group which is not desirable.

Hey guys,
I did an experiment to practice Multi Shader using a very simple material, SSS and a little displacement. But I noticed a lot of slowness to render this image. Are there some parameters that we can adjust to drastically reduce this render time? My processor is not the worst, I'm using an i9 12900K and honestly a scene like this in 5K would take more than 5 hours letting it clean well. It doesn't make sense to me.
I stopped the render at 8% noise, the noise reduction is undoubtedly very effective, but I still think it takes a lot of time for an image like this.
I would appreciate any help on this.

[C4D] I need help! / Bump texture rendering too smooth
« on: 2022-06-29, 02:12:54 »
Take a look at this example, why is this procedural texture rendering too smooth on the bump channel? That's not working as expected. If you connect it into the displacement channel, it is rendering properly.
We should  have a pretty close representation of this texture on both channels.
Is there some parameter I'm missing in order to make it work properly?

[C4D] Feature Requests / Add connected new nodes

If that's a duplicate, please delete it. Would be very nice to have the feature of right clicking over a connection to add a new node already connected. I think 3Ds Max behaves like that, a real time saver.

[C4D] I need help! / Bump noise projection issue
« on: 2022-06-12, 04:59:36 »

Why I'm getting this weird bump projection. I couldn't figure it out what I'm doing wrong.

The curious thing is that when I open a new scene and apply the same noise over a sphere it doesn't happen.

[C4D] I need help! / Metal highlight compression
« on: 2022-06-09, 17:53:19 »
Hello there!

In a situation like this where we would like the ground plane to be quite white (not gray) and at the same time preserve the nice gradients from the light planes over the metal. There is a way to recover the highlights of the metal lid without compromising the white of the ground plane. If we increase the value for highlight compression too much, everything starts to turn gray and lack contrast.
This is a question where I always have to save two images and compose in Photoshop, am I doing something wrong or is there a better workaround for this?


Hi guys, take a look at this. Same file, layered material working good with SSS. When I turned off SSS for the Choco inside material and turned on Volumetrics, it seems to be going wrong. Absorption color is set to black. Why am I getting full transparency for the material?

How can we make the top layer displace inwards?

The add blending mode does not act like adding. Is it not supported?

[C4D] I need help! / How to increase SSS effect over 100%
« on: 2022-06-05, 20:23:29 »
Playing around with SSS to get closer to the reference, but it seems SSS in Corona doesn't offer to much control straight out of the box.
The effect is to weak and we should be able to go further than the 100% in order to achieve a more real visual representation.
Any idea how to do that?

[C4D] General Discussion / Displacement settings
« on: 2022-06-05, 19:17:18 »
Hi guys,
Figuring out how to deal with these settings and I could notice that the value of 2 is a good balance but still leaves some artifacts. What is the drawback in lowering this number? longer renders times, memory?
Also, what is the World Size option for?

Does Corona have any documentation files? I couldn't find it on Chaos' website.

Current state to object is not supported? Can we move/scale/rotate individual clones?

[C4D] Feature Requests / Bring scatter clones closer option
« on: 2022-06-02, 20:29:55 »
Hi Guys, would be nice to have an option to bring closer the clones inside the defined areas (splines). Sometimes you have a few clones, but they end up too far from each other. And if you size the spline down you mess with the clones.

Does it make sense?
