[C4D] General Discussion / Re: vray max to corona c4d

Falloff with a custom curve > Fresnel map (you can create a custom curve in it)
Composite (multiple layers, masks, different blending options) > This one is tricky. I am not a C4D expert, but I think the only way would be to stack multiple Fusion shaders or Corona Mixture shaders.

C4D's layer shader is quite capable of doing all sorts of layering with masks and different blending options, for a lot of layers in a single node.
Fresnel could be a bit tricky, as far as I understand you can use maps as inputs in max whereas C4D just can use plain colors. But with masking you should be able to achieve pretty much the same.

I can't make out much from the blurry screenshot, but if the material uses native Max nodes that don't have an equally capable counterpart in C4D, a one-to-one translation might not be possible.

[C4D] I need help! / Re: Animating the size of lights, but not from centre?

« on: 2025-06-10, 12:13:51 »

Yes, it's the Geometry Axis node. As all my lights are in a Null it affects them all. But I just realised that I can put the light I want to change the axis centre of into a child null and put the Geometry Axis node in that.
… or just make a light material for that light. That might be easier.
Thanks for your input.

Even having all lights in a Null does not matter when you place the capsule as a child of the one specific light.

[C4D] I need help! / Re: Animating the size of lights, but not from centre?

« on: 2025-06-09, 23:55:27 »

Is there a trick to animating the size of a light? I have a rectangle strip light and I want to animate the size to illuminate part of an object. But I want the light to grow from one side and not the centre which it does by default. I thought maybe the Axis Centre node would do it but it messes with all the lights in the scene. How might I solve this? Would it just be to animate a shape that blocks the light and not the light itself?

What's the axis centre node? I only know the Geometry Axis capsule and it leaves other lights alone.

In the Max forum you can find a few pointers..

[C4D] General Discussion / Re: Scatter lights?

« on: 2025-06-02, 19:52:43 »

I have an inkling:
When you use Corona lights as "Instanced Children" in a Scatter object, you cannot see the instances in the viewport, which looks like there is no cloning happening but it is. When you render, the lights are there.

I think this is the issue.
I could be wrong, though, but I don't think so ...
It's a jungle out there!

Rewatching Monk ATM ^^

PS
I think there is a bug hidden in there. The lights should be visible nonetheless and when I switch the viewport display mode to Full, I can, for example, see 3 lights of 12 that I entered in Surface Sc attering "count".

Thanks. yes you can adjust and so on. But generally, how many human's can you put in an image that are on their mobile. It simply reduced the Chaos Cosmos library by a lot.

If you want to mimic reality, you sadly can't have in too many ^^

« on: 2025-03-03, 17:06:57 »

Hi,

i see we dont have any new betas/daily versions on v13 or v12 service packs.

are they planned to come back, or is there a rough schedule on next versions/features planned?

I have this inkling it won't be long till the next daily and even might have an idea or two what's to come.


I might look in the dailies section of Max every now and then, kinda spying ^^

[C4D] Bug Reporting / Object with Weight tagh does not render

« on: 2025-02-21, 16:47:10 »

This only concerns the IR, not the final render.
When I start IR with this scene, the bots do not render. I need to remove the weight tag to correct this.
The problem also occures with a fully rigged object (where the weight tag comes from), I could narrow it down to this simplified scene.

Win 11 24H2, Cinema 4d 2025, Corona Version 13 (Daily Build Dec  9 2024)


Btw, thisa must be a regression, I could swear the same scene worked fine with a previous version of C4D and Corona.

I'd try to find out more with the Event Viewer and then check Google for more information. The even viewer logs essentially everything.

« on: 2024-11-22, 20:25:04 »

I remember bugs I reported in 2019, 2020 and 2021 giving "yellow results" but the issues were gone. Probably not quite and or maybe they returned.
I'll check when I find the time.

https://forum.corona-renderer.com/index.php?topic=26050.msg155291#msg155291 - Probably fixed.
https://forum.corona-renderer.com/index.php?topic=29538.msg170934#msg170934 - Probably fixed.
https://forum.corona-renderer.com/index.php?topic=26052.msg162949#msg162949 - Alive and kicking.

See nan.c4d - change the offset in the Projector shader and get a nice yellow color.
No idea if or how it is related, but just in case ...

[C4D] I need help! / Re: HELP! Displacement artefacts in texture and triangular lines in rendering

« on: 2024-08-12, 17:18:09 »

I spot 2 things in your scene:
First, the normals are reveresed which should reverse the displacement. Displacement only "knows" where front and back are because of the object normals. Fix this first.
Second, the topology is bad. There is no sugarcoating this.Corona's displacement is very robust, contrary to some methods the competition uses, but it is not unbreakable, as you can see for yourself. Long triangles will cause problems. If possible, use retopology on the surface. Maybe even the quad-remesher alone will help already. If you need displacement, I do not see any way around that. Remember that some materials rely on working UVs, though. What material are you using?

[C4D] General Discussion / Re: Vantage Live View & Camera animation ETA?

« on: 2024-07-08, 19:16:58 »

We don't get into discussing when something will show up in a daily, as there are just too many unknowns. All we can ever say is "planned for Corona 13" (until we say "it's out now in a daily" ;) ).

You have a (vantage) point there!
