[C4D] I need help! / Problems with Displacement Material: Material from Corona-Material-Library

« on: 2023-03-09, 18:21:57 »

Hi

I am currently rendering a carpet using the carpet material from the Corona material library: Carpet Office

Here a render error appears that I often have with displacement textures: if I have a surface that consists of multiple polygon lines, the texture makes errors (see picture in the attachment) The green floor has strange dark green areas that are not shadows! These spots are exactly along polygon lines.

Now I have melted the polygons to a surface and still, these dark spots appear. It does not matter if I use UVW oder Cubic texture mapping.

Do you know any advice?

Thanks and Best, Katharina

[C4D] I need help! / problem with mapping a displacement texture / alignment error

« on: 2022-08-30, 19:11:15 »

Hello
I have a problem with mapping a displacement texture:
As you can see in the image (attachment), the texture currently has an alignment error in the facade rounding at the top left. The way the wood shingles run in the top right of the rounding is correct.
I am using C4D R25 with Corona 8 Hotfix 1 and the model is created in Archicad.

The shingle texture I got from the Corona internal library: Wood Siding Shakes Oak

Thanks for your help!

[C4D] Bug Reporting / Plugin Error: Corona Core

« on: 2022-01-08, 17:20:55 »

Hallo

I need urgent help please. I want to render a scene in C4D with Corona Render and shortly after I start the render process C4D crashes with the following message:
The plugin CoronaCore has crashed.
More information can be found in
'/Users/katharinabayer/Library/Preferences/Maxon/Maxon Cinema 4D R22_F2A48324/_bugreports/_BugReport.txt'.

After clicking 'OK' unsaved scene files will be saved as '_bugreports/_recovery_xxx.c4d'.

I have already sent the report to the manufacturer under CYAAN - do you know any help how to fix the problem?

Best regards and thanks

[C4D] I need help! / help: creating wrinkles in fabric-material

« on: 2021-03-19, 11:05:15 »

Hello

Do any of you know how to use corona material well to create a fabric material that wrinkles like in the reference picture? The difficulty is that the folds should act like a stretched fabric, therefore starting from the corners. Depending on the size of the area / format of the extended sun blinds, the folds would have to adapt. How do you do this?

Best regards

[C4D] I need help! / need help: corona distance shader to create path in meadow

« on: 2021-03-19, 10:55:43 »

Hello

I need help please. I use the plugin "Surface Spread" for cloning objects in C4D. With it I have created a test-meadow on a surface. Now I'd like to use Sweep-Object to spread out a path, analogous to the official Corona render post (https://blog.corona-renderer.com/corona-renderer-6-for-cinema-4d-released/). So the grasses should be cut out along the sweep and then slowly spread to the dense meadow. Attached is a screenshot from the Corona homepage.
I have now created the meadow, as well as the sweepnurb.
I have also created the distance shader, but unfortunately it has no effect. In the attachment you can see my settings - what am I doing wrong, can you please help me?

1: Has the Spine of the Sweep to be set on 0 Y-level, cutting into the surface-spread-distribution-plane, or should der Sweep hover over the surface-spread-distribution-plane as now in my setting?

2:Is it right to connect the Cloning-Object (surface spread) to the distance shader by putting the cloning object into the shader effector selection (see screenshot: Shader Effector)

3:What should the values in XYZ at the Shader Parameter (see screenshot: Shader Parameter) affect?

4:Is the way how to setup the distance shader right (see screenshot: setup distance shader1+2)? How should the Near color and Far color affect?

Best und thanks, Katharina

[C4D] I need help! / Why is Team Render slower than Single Render?

« on: 2021-01-28, 21:07:27 »

Hello

I am a bit disappointed, I have connected a second iMac (4 cores) called "B" to my standard render iMac (10 cores) with Thunderbolt to render an image sequence.

The strange thing is that if I render with iMac "A" alone, the rendering process is faster than with team render.

Can someone please explain to me what I am doing wrong?

Many thanks, Best,
Katharina

[C4D] I need help! / Team-Render / Asset Error

« on: 2021-01-26, 20:32:08 »

Hi

Does anyone know how I can solve this error, that pops up by starting "Team Render to Picture Viewer"

 ERROR: "Saving Failed: Could not create Job because all needed assets could not be extracted"

In advance a window popped up showing some texture names, but in the project itself these textures are not missing


Thanks for your help!

[C4D] I need help! / Animation in C4D/Corona | Collection of questions

« on: 2021-01-26, 11:37:37 »

Hello

I am currently trying to render simple animation in Cinema/Corona and have some questions for you.
For example, I want to point a camera frontally at a building facade and move this facade from left to right frontally.
Would be great if you can help me with this.

1. animation as MOV / MP4 file versus Image Sequenze as PNG/TIF
I have read that it is better to render image sequences, because in case of a crash the render time is not completely lost. How do you see this? Do you render the stills as PNG or TIF? How many bits?

2. when I render image sequences, is there a way to also export the Corona multipasses so that I can later work with masks in Davinvi Resolve for example?

3. reduce render time via UHD Cache: how does this work in C4D/Corona? I found this link here for 3ds Max /Corona (https://coronarenderer.freshdesk.com/support/solutions/articles/5000515648-how-to-use-the-uhd-cache-for-animations-and-stills).
Under point 1 it says "For example for 400-frames animation, you can set 3ds Max to render every 50th frame to render the UHD Cache only for 8 frames." where can I set this in C4D?

4. what influence do the camera settings have on the render time?
e.g. shutter speed and DOF.

5. do you have any tips to shorten the render time without losing image quality? Especially for slow camera movements where many stills are necessary?

6. do you know any good video tutorials for creating videos from Cinema/Corona? Or gladly also good online courses?

Thanks for your help!

[C4D] I need help! / Material Name shows up in Work space / how to get rid of?

« on: 2020-10-28, 09:07:24 »

Hello

I sometimes have the problem that a material name - in this case "ETERNIT" - is linked to the workspace window. I send you a screenshot, it is shown in the top left window. Do you know how I can remove it?

Thanks!

[C4D] I need help! / Problem with Material using Displacement

« on: 2020-10-08, 12:04:12 »

Hello

I have the problem when rendering with materials that use displacement (carpet, gravel) that the material draws the polygon geometry. I send you a test scene with a test image so you can see what I mean.

Do you know a solution?
Thanks a lot,

[C4D] I need help! / Material converter doesn't work

« on: 2020-10-08, 11:37:27 »

Hello

I work on Mac and had to update to Catalina. I use Cinema R17 and Corona version: 5 hotfix 2.
Since then, my Corona Material Converter no longer works - does anyone know why?
If I create a new Cinema 4D material I can convert it, but V-Ray materials cannot be converted.
