[C4D] General Discussion / Any chances to improve render times with volumetrics material?

« on: 2023-01-13, 03:00:55 »

I'm rendering a 5K image and the render estimate is 4h 30m on an i9 12900K. This is impractical. I don't know what I do, it wouldn't be my choice but I think I'll have to go to another renderer. On Redshift it should take 5 min.

[C4D] General Discussion / Can't save Tone Mapping adjustments

« on: 2023-01-10, 22:51:27 »

Hi guys,

As far as I remember I didn't have that problem. Why are tone mapping adjustments not being applied when saving images?

[C4D] I need help! / Masking - leaking issue

« on: 2022-12-27, 17:49:49 »

Hi Guys, it was not supposed to behave like this, but I couldn't figure it out how to solve it. The textures are working fine in other 3D softwares.

[C4D] I need help! / Bump channel not working with layer node

« on: 2022-12-10, 01:34:59 »

Hi guys,

Well, very basic set up. I can't make it work. Any particular reason? Something I'm missing?

I'd appreciate any help.

[C4D] Feature Requests / Better render times for volumetric scattering

« on: 2022-12-04, 03:19:07 »

Guys,
Don't take me wrong, but 20 min for a 1K image on an i9 12900K is disappointing once we look at GPU render engines out there. The same image at 4K would take 5h and 30m or even more. That's out of question!
Do you think it's possible to reduce it considerably? Honestly, volumetric scattering in Corona is one of its treasures IMO and I would love to keep using it, but it impracticable the way it is.

[Scatter] I need help! / Scatter over displaced surfaces

« on: 2022-12-03, 00:17:07 »

Hey guys,
I couldn't figure it out but that came to me, and I think there is no option for it. Is there a way to scatter over a displaced material?
As you can see, some of them get flying and others are hidden. For very small things that becomes a problem.

[C4D] Feature Requests / Right click over a connection to add a new node in between

Would be very practical to be able to click over a connection line to add a new node in between.

Does it work with Corona Camera tag?

[C4D] General Discussion / Layered Material Issue

Hi guys

Why can't I make it work? It seemed to be working on the last version.

[C4D] I need help! / UV distortion on sculpted objects

« on: 2022-10-31, 20:41:50 »

Hey guys, if you don't mind how can I solve this issue. I have this leaf with some sculpted details and proper UV layout.

As you can see if you check the mesh with the sculpt tag off it is working fine, but if it is on, some distortion is happening for some reason.

I've already done that before and I don't remember this causing any problem.

[C4D] I need help! / Selection tag for masking

« on: 2022-10-21, 02:56:18 »

Hi,
I was wondering if it is possible to mask a texture in the roughness channel with selection tags. For example, suppose you want to apply a roughness map to only half of a sphere, how do you do that?

[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

[C4D] General Discussion / Physical materials - Volumetrics roughness issue

« on: 2022-07-20, 03:53:51 »

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.

[Scatter] I need help! / How to scatter objects in other scattered pieces

« on: 2022-07-13, 20:35:45 »

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.

[C4D] General Discussion / How to optimize render time using SSS

« on: 2022-07-13, 17:41:30 »

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.
