[C4D] Bug Reporting / Shading issue
« on: 2022-05-11, 10:37:18 »
Hi there

Just got something that doesn't look right to me. Can you check it out?

Thanks and have a good day

I can't see this shader in C4D, hope we will get it soon.
Or did I miss something?

[C4D] Bug Reporting / Issue with fields
« on: 2022-01-28, 21:25:55 »

I have some issues using fields.
- I'm using a vertex-tag to control Surfacespread
- This vertex-tag has fields activated
- Drag and drop another vertex-tag into
- corona starts to get buggy

Private uploader isn't working right now, I will upload it later when it's working again.

Include/Exclude in slicer material isn't working. I can't drag and drop an object into the Include/Exclude field, nor I can select an object.

Can you check this issue?

Render or multi instances (I didn't test normal instances) are not rendered in IR when I use alembic particles as source for the cloner.
Rendered in picture viewer gives me the expected result.

[C4D] I need help! / Vector Displacement
« on: 2021-09-20, 17:18:08 »

Cool that you added vector displacement! But can someone explain, how it works?
I don't get it working... Native C4D renderer does the job fine for me.

How can I bake and use vector displacement like in native renderer?

If someone knows more, please give me a hint :)

[C4D] Bug Reporting / Proxies not rendered
« on: 2021-08-24, 18:04:13 »
If I remember correctly, this issue is old already.

- Corona Proxy cloned using multi instance
- Expected result in IR
- Not renderer in final render

C4D R20 (please check this issue with R20)
Latest version 7 + 8


It still happens that objects with displacement disappear in IR. I'm not sure when and why this happens, it looks very random to me. It happens daily and in every scene.
They appear again when I change something of the object like move a polygon or change material. 

Can you confirm this behavior?

[C4D] Bug Reporting / Slowdown when using BumpMap
« on: 2021-04-05, 19:29:46 »

I'm not sure if this is connected to the latest daily, threadripper processor or something else.
When I render something with a material applied that includes bump map, my CPU is using less than 100% of its power (depends on scene, in this case less than 50%)
Noise in bump slot renders fine, as well as normal map.

It happened in every scene I opened today.

Here is my separate post for my second issue with denoiser. First post:

When I choose Nvidia denoiser, activate multi pass, virtual beauty and set denoise amount to 0, the pass still gets denoised.
It happens only when Nvidia is activated. 

This is clearly an issue to me, even it's the same in max. Nivida denoiser has also denoise amount where you can tweak the blending between 0 and 1. 
I would assume that it should be possible to save both versions.

The workaround now is to do it manually, but this is not satisfactorily.

Thanks and have a happy day :)

[C4D] Bug Reporting / Intel denoiser - visible seam
« on: 2021-02-10, 21:52:14 »

I'm not sure if you are aware of this issue, I don't even know if this is a corona thing or a limitation of the denoiser.
I noticed last summer already, that Intel denoiser leaves a visible seam in the middle of the image. (to be more precise, a few pixels to the right, see example)

To give you some information: I rendered the image two times.
At 3240 X 2160 gives the result I expect. When I try it with something higher than that, then I get always a visible seam. Happens in all scenes, every time.

[C4D] Feature Requests / Full support for noise and layer
« on: 2021-02-10, 00:19:33 »
I know that you are aware of this issue, but I want to bring this up again.

C4D noise is still not working correctly if you set it to world space and place it inside a layer or fusion shader.
I think the strength of noise is its world space mode. But you can't combine them because this issue remains unsolved.
So only one noise or everything in UV space. It's a huge handicap when you are creating more complex shaders.
This is a bit frustrating to be honest, and I hope you can give some love into this. I understand that fixing such things isn't easy, but nevertheless I would describe this as a basic feature which should be supported.

I really hope to get full support for noise and layer.


[C4D] General Discussion / Scene parsing
« on: 2021-01-27, 00:21:59 »

I'm a bit confused about scene parsing. I noticed that my CPU is just using around 12%-13% of its power during scene parsing. Is this normal? What is your experience?
In my view this is too slow, and I think there must be an issue, maybe the setup of my scene or c4d/Corona.
So I'm interested if you experienced something similar and how you deal with it. :)

I did some tests as well. RAM usage less than 50%.
First test: Multithreaded parsing off.
Geometry parsing: 0:09
Scene parsing: 8:55

Second test: Multithreaded parsing on.
Geometry parsing: 0:08
Scene parsing: 8:55

I would expect a speed difference here. Is that how it works or maybe an issue?

Another issue by the way: Put a proxy under a clone object and change it to multi-instance. It renders fine in IR, but it doesn't show up in PV.

[C4D] I need help! / Baked Displacement
« on: 2020-06-27, 12:35:13 »

I struggle with displacement which is baked from high-poly mesh to low-poly.
I get always artifacts along the edges. In this case, I used the C4D tool for baking but I get the same when I use a different software.
C4D nativ render result to compare. I get similar artifacts with C4D when I activate "Round Geometry" in the displacement channel.

Do you have a hint for me what I'm doing wrong?
Thanks and have a nice weekend!

[C4D] Bug Reporting / Corona Tonemap Control
« on: 2020-06-18, 15:57:00 »

Corona Tonemap Control isn't working for me as I would expect.

The ground has a light material with corona Tonemap control applied. If I change as example saturation, everything is affected.

Can someone confirm that or give me a hint what I'm doing wrong?
