[C4D] General Discussion / Camera settings difficult to understand

« on: 2025-07-08, 18:11:33 »

I haven't rendered for a few months and somehow I can't get the camera settings to do much if at all.
There are four settings that can override to do nothing or all :
- Corona preferences
- Corona VFB
- Corona tag attributes
- Camera Attributes

I can set the VFB when I use the simple exposure settings but any other way to control exposure seems without effect.
I have attached a file. The only way to control exposure is by simple exposure. Other ways by setting shutter speed or aperture have failed to have any effect.

Any help appreciated.

[C4D] Daily Builds / Cluster scattering

« on: 2025-06-11, 15:55:58 »

Does it already work and if so an example or a few hints how to get it started. I don't get any results no matter the settings for a procedural cluster scattering.
Seems to be a great new feature.

[C4D] General Discussion / Chaos Cosmos on the phone

« on: 2025-05-06, 18:53:20 »

Just a little tip for the Choas Cosmos models.
Waving people, pointing people or people on mobiles are useless for me. Maybe its just me but I try to avoid those unnatural posed models.

[C4D] General Discussion / transfer license not possible with C4D not properly quiting bug

« on: 2025-02-09, 00:03:19 »

Since Cinema4D with Corona installed (daily build 13) does no longer quit at quitting the app (it stays active in the background) I forget to force quit Cinema4D at the end of the day only to find out at home I can not work with Corona.

Can this bug be resolved so that I no longer have to hassle with the Corona license.

Hope the above makes any sense.

Gallery / shadow catcher and hdri, no need to model the terrain

« on: 2025-02-01, 23:20:26 »

Recently I have been using the shadow catcher to have shadows on my hdri's in my design studies.

Here is a house I designed and did a few renders for. The hdri is https://ambientcg.com/view?id=DaySkyHDRI049A
The vegetation is from Maxtree. There is no terrain in this model. Saved me a lot of time.

[C4D] General Discussion / Randomizer distorts textures when the material tag is set to cubic

« on: 2025-01-13, 12:07:32 »

I noticed that the material radomizer with Cosmos materials can cause problems when I set the material tag to cubic to edit the size of textures.
Is this avoidable in any way or do I need to edit the Cosmos materials for each setting where the randomiser is set.

See attachments.

[C4D] General Discussion / Corona/C4D versus Twinmotion render test

« on: 2025-01-08, 11:24:59 »

Tested Coronarender (C4D) versus Twinmotion at the same resolution, same free fbx model from Dimensiva.
I also did a test with the same model in a room with HDRI Cosmos studio lighting.
I did not add the texts in the Coronarender. Was just interested to see if TwinMotion is relatively comparable these days. I think it is. This render did not contain any displacement, the lighting and materials are rather simple. The Coronarender materials where from the plastic presets adjusted for color and transparency.

Gallery / 2025 rendered on a MacBook Air M1 from 2020

« on: 2024-12-22, 18:45:12 »

Did a little 2025 project on my m1 MacBook Air M1 from 2020. 16Gb.
Tried to do something similar with Redshift but Redshift seemed unresponsive most of the time so I gave up.

All modeled in C4D with only Cosmos assets, no postprocessing just straight from CR.

I am surprised to see CR not crashing once,  with IR on most of the time and at final renders even though it swapped about 2Gb memory. Rendering on a MacBook Air M1 without a ventilator hardly getting warm.

A huge advantage of C4D/Coronarender is being able to do work like this on a cheap lightweight laptop still for sale well under a 800€ or new for a few hundred euro more. The file has decals, C4D/2025 booleans, lots of Corona-scatters and proxies for the trees and displacement for the landscape and concrete and is rendered at 3600x3600.

[C4D] Bug Reporting / Force quit C4D after render

« on: 2024-12-20, 11:32:56 »

OSX 15.1.1
C4D 25.1.0
CR 13 dec 2024
Mac Studio m1 128Gb.

C4D won't quit after render. The app closes but remains active in the background as not responding. I need to force quit C4D to completely shut it down. Not a real problem but still.

CR13 dec. 2024 seems to work well  so far. Been doing work with it for a few days with Maxtree and Graswald libraries, Corona scatter and C4D's 2025 new Boolean features and I did not crash once.

General CG Discussion / The State of 3D Modeling, Rendering....

« on: 2024-12-14, 22:00:47 »

Interesting and recent statistics by RebusFarm
https://rebusfarm.net/blog/the-state-of-3d-modeling-rendering-and-post-production-tools-insights-from-the-archviz-community

A few observations:

•CPU/Coronarender at the top ! Could it be that Rebusfarm results are influenced by CPU people that benefit most from a render farm. GPU people most likely don't need a render farm.
•Cinema4D lost some, Rhino too, I think to Blender
•Sketchup lost a lot. Having been using Sketchup a lot in the past, I found Sketchup to be very slow in modelling and texturing. I think that's why it's in decline.
•ArchiCad is growing. I think because it's BIM. Great if you can combine archviz with BIM. Was not a good idea for Corona to drop Archicad.
•Revit should be listed higher being used at such a large scale, probably not a modeller for renders.
•Unreal and twin motion are growing steadily I think since they are free apps
•Lumion lost a lot. Great app but their pricing was not competitive. Don't think they will be around a few years from now.
•Vray lost a lot too. Wonder why, 3ds max is still hot. What are they rendering with ?
•1069 votes and 2% C4D users in decline , that's about 21 C4D users and about 630 3ds users in this study. Hopefully this does not represent the corona-userbase for C4D very well otherwise I can't imagine C4D being supported for much longer. Especially now Redshift is for free with C4D and Redshift has a better integration with its assets in the C4D-asset browser. For people like me on a Mac, corona render/C4D is still the best option though.

[C4D] Daily Builds / Who has the Mac M4 pro or max

« on: 2024-11-11, 01:40:19 »

I would love to see any Coronarender benchmarks with the news Mac's M4.

Test done when I got a Mac Studio 20 M1 cores comparing to my old iMac 4 Intel cores I noticed that render times improved by mostly just by about core count.

Maybe the new 14 or 16 cores M4 would still be slower than the Mac Studio M1 with 6 to 4 cores more. The M4 single core speed is impressive and maybe we get a lot faster scene parsing and times to first pixel

[C4D] Daily Builds / surface scattering density pattern

« on: 2024-11-04, 13:58:39 »

Just saw this, is this new in 13 ?   I like it a lot, works great with vegetation and very easy to set as well.
Could not find any info on it in the manual. Is there any way to set some parameters? like amount and how these density patterns are related to the base scatter object.

[C4D] General Discussion / can no longer find the "delete duplicate materials" script

« on: 2024-10-18, 23:30:52 »

Hi,
There was someone here at the forum who had a small script that deletes all duplicate materials. Very handy when working with Maxtree trees and plants and when using the C4D asset browser.

I lost the script when reinstalling my system so maybe someone still has it. I did a search but could not find it.

[C4D] General Discussion / Can not import Cosmos assets in the C4D database, anybody ideas

« on: 2024-10-02, 12:05:38 »

I am trying to import the Cosmos assets in to the C4D database system. I got about 600 people models done now. Fairly easy process.

But I tried to put Cosmos Haworth assets in the database and only part of those assets import in C4D 's database.
I duplicate Corona Cosmos proxies to mesh before moving them to C4D database. But still.

I need to do this since the Cosmos browser has its moments and moods and I often get stuck before a deadline.  I would love to move Cosmos assets to a more robust location like the C4D assets browser.

[C4D] Bug Reporting / Chaos Cosmos does not work OSX 15.0, CR12 hf2, C4D 2025.0.1

« on: 2024-09-28, 22:11:20 »

I followed the I instructions but there is no database to copy in the menu, the files to be deleted do not exist, cbservice quit does not help. I have the latest Cosmos and reinstalling does not help either.

I have a fully updated Macbook with the versions mentioned above. My Mac Studio has not been updated yet and I got Cosmos still going there. Would love a one click solution to download all Chaos assets into the C4D database. Cosmos is the wrong direction for Chaos assets for C4D.
