Thank you so much for your support.
I will give it a try to figure it out :)

Thank you for your reply. This means the to use it for dirty corners and so on is not really the correct way then ?
Or to put it in other words :
To make a concrete with worn edges it would be correct to go with the curvature tool ? Or what would you recommend to have best control on this ?
How would you control the direction offset ? It seems this is only possible with AO ?
Thanks again :)

Hello
So I tried the Corona Curvature. Basically this is a nice feature, but still have similar problems, since the red colored edges shins through the outer geometry. See attachment with settings.
Also I do not understand the logic of the AO. Why is there an effect visible although two elements are not intersecting at all ? See the two cubes.
This seems to me the main problem as it should only influence surfaces when they are really touching, no ?

Dear Community
I have a question regarding the AO shader, mostly used for dirty edges. I use it for concrete objects in architecture.
From time to time a face a problem I can not solve as the Max. Distance also includes the objects surfaces, not only the edges.
See screenshot with the object gets colored red in thin parts or where surfaces get close.
For me it seems impossible to make a thin object (concrete plate) without getting dark or colored on the surface when Max. Distance is bigger.
Is there a work-around or a different function ?
Thank you so much for your help.

[C4D] I need help! / New vs. Old Material System / Reflection Amount
« on: 2022-02-10, 18:54:05 »
Dear Community
Since the release of the new material system with Physical material I miss the option to control the exact intensity of a reflection.
This was possible by using the Level-Amount or even apply a color in the Reflection Tab in the Old System (Legacy Material)
It was possible to create surfaces that have 100% Glossiness but would reflect only 50% if needed. IOR would stay the same.
This was helpful for less reflective glass surfaces to create an anti-glare effect for switched Computer or Tablet screens.
How would this be correctly done in the new system ?
What is the logic behind it ?
Thank you for your feedback :)

[C4D] I need help! / SHADOW CATCHER ON OBJECT / WRITE PNG ?
« on: 2021-11-26, 15:15:42 »Hello Community
I have a (hopefully) simple question.
I would like to have a simple object like a cube that is above a landscape and casts a shadow caused by Sun/Sky or an HDRI on that landscape. See attachment.
Is there a possibility to have the scene rendered with just the cube and the shadow to get a transparent PNG file featuring both elements ? Without the landscape and background visible ?
I would like to have the cube with the shadow in Photoshop so I can put different colors in the Background.
How do I get that shadow and the object as one thing ? Is this even possible ?

Thanks a lot !

[C4D] I need help! / Re: Surface Problem – Broken Geometry along Edges
« on: 2021-10-28, 21:32:42 »Hello and Thank you !
Actually I was able to eliminate the failure this evening.
_
The problem is caused by the import option in the DIN3D plugin.
If someone is encountering the same problem you have to change the settings for Optimization. Uncheck Optimization for points or change the radius !
This solved it for me. Still I do not know why it is different in final render and the preview. Maybe because of reduced accuracy or interpolation.
Would still be nice to know what makes the difference.
Have a good evening.

[C4D] I need help! / Surface Problem – Broken Geometry along Edges
« on: 2021-10-28, 15:48:43 »Hello
I am very satisfied using Corona Render together with Cinema4D. I usually build models in ArchiCAD and use the DIN3D Exporter. So a quite common setup that works very well.
Still I sometimes recognize the same problem with subdivided plane surfaces. There seems to be an edge break along the diagonal line in the model.
It has nothing to do with the material, the Phong Tag or the Mapping.
It is invisible and always correct in Interactive Rendering preview. But the final render is always wrong. This is very strange, no ?
I have attached two images and the file where you can see the one surface creating that shaded diagonal.
It would be great to know what is the exact problem with the model or the scene to avoid this things or create a proper workaround.
Thank you so much for your help.

Hardware / Re: Corona and Apple Silicon
« on: 2021-01-21, 12:04:32 »Hi,
Corona plugin isn't fully ported yet to natively work on M1 processors, but you can still run it using Rosetta.
First, please install latest daily build of Corona v7 if you don't have it already.
Then, you need to make sure Rosetta 2 is installed. You should be asked to install it any time you try to open any application that is compiled for Intel processors, so there is a good chance you already have it on your system. The quickest way to check it is to try to open Corona Image Editor - it should either open directly, meaning you already have Rosetta installed, or ask you to install Rosetta.
Afterwards, you can just switch your Cinema 4D to start using Rosetta so it can load Corona plugin. To do this, find Cinema 4D in you Applications folder, right click (or ctrl+click) its icon, select "Get Info" and check "Open using Rosetta". After this you should be able to open Cinema 4D as usual and Corona should load normally.
We realize this is not perfect and we are already investigating native support of M1 processors.
Thank you a lot. This is good news.
I have been working on Mac with Cinema4D and Corona for years. It works like a charm and I am more than happy to hear you are already investigating on the support of the new chips.

[C4D] I need help! / Re: Reflection Issue / Wrong in VFB / Correct results in Interactive Render
« on: 2020-10-26, 09:13:09 »Thank you very much Michael
I followed you advice and you are right. Changing the phong for the green panels worked !
Regarding the glass it did not – maybe because it also affects refraction as well ?
But more important : You pointed out a geometrical problem. Excluding this corner from the scene did the trick. So it is obvious that the error seems geometry-based.
Without the corner-element glass and panels are looking fine now. So I have a solution.

But still interesting : Why is it correct when using interactive render ?
Do you have an idea ?
Thank you so much

[C4D] I need help! / Reflection Issue / Wrong in VFB / Correct results in Interactive Render
« on: 2020-10-25, 16:29:00 »
Hello
I am struggling with a major problem. Since years I build and render buildings with the same workflow. I never had this kind of problem.
I have a simple model of a facade. When I render with interactive render mode everything looks alright and as it should be.
Starting the render inside the VFB the reflection is in some parts completely broken. It almost looks as if bended / distorted.
Also I noticed that the reflection breaks along the polygon lines.
You see it in the lower glass panels as well as in the green facade panels, where the reflection goes missing. One green panel is just dark.
_
I work with Cinema4D 18 and Cinema4D 22 and have tried to render with Corona V5 and V6.
This is a very strange behavior as in interactive mode Corona-Render does the right job ?
Attached there are two screenshots. Also there is the scene I use.
Thank you very much for your suggestions and help.

[C4D] Daily Builds / Re: Corona Renderer 6 for Cinema 4D daily build
« on: 2020-09-04, 11:52:30 »I have a minor issue with the Corona VFB...Mainly it won't go away, meaning I cannot close it. I can only minimize (or maximize). Also the image will not fill the VFB (see image below). I can zoom in and out as before but the window pane stays the same size.
Same here. I cannot resize the VFB or the Error Reporting windows. The content will not resize to match the window. I have attached examples below.
Thank you!
Same issue. I can not operate Corona V6 with the released build. Using Cinema 4D R18.
Hello,
can you please share your MacOS version? We are unable to reproduce it at our local machine and would really appreciate any bit of information about this issue.
Thanks,
Jan
Sure. Currently I am working on macOS High Sierra Version 10.13.6
Thank you for your effort.

[C4D] Resolved Bugs / Re: corona image Version: B1 (core 1.7) crash everytime on OS X yosemite
« on: 2018-11-13, 15:36:39 »Hello HFPatzi
Thanks for the tip with the lock screen. Basically it has never been an issue but who knows. I will keep it unlocked for the next renders to see if it makes a difference. What I did anyway is to block the MacOS Sleeping Mode for the hard-drive. This really forced my C4D to stop working until I logged in again.
I speak german so I could read everything. Danke !
