just to keep the enthusiasm for CR. I rendered a file yesterday with lots of Maxtree assets up to 3.25 Gb and my Mac Studio 128Gb rendered it all without crashing once even during all the iterations before the final render.
I used the edge trimmer for the grass which works very well since C4D allows you to select the texture opacities and set them on edge trimming all at once.

C4D became  slow though, I could only handle the file in wireframe view . Scene preparing by CR also takes a while, a few minutes.  I wonder if other render engines for GPU rendering would allow for much faster iterations and save time to first pixel. The render times for the final high res renderings are less meaningful to me. Since overall most of my time is spend on modelling, vegetation placement and render interations on low res.

[C4D] General Discussion / C4D 23.2.0
« on: 2023-04-01, 23:39:02 »
Just installed the newest C4D 23.2.0
Corona seems to be ok on it.
Be careful though. C4D installed by erasing my previous version including all plugins. Had to reinstall those. Mac OS btw.
Maybe there is a way to prevent this.

I am a bit in a hurry and can't provide files and examples.

But I still have lots of difficulties to set a material colours with the sliders. Setting goes everywhere randomly.
I tried Corona Pattern with a gravel mesh but on anything else than a plane that is undistorted or scaled the patterns do not behave properly. I get flat gravel on each part of a plane that I scaled. I do mnot remember it was so difficult to set a pattern. Now after hours of trying I gave up. It simply does not work. Back to displacement. Pity, I liked the patterns.

General comment. It seems to me that Corona render is getting more and more difficult to use and to navigate around the many little and bigger bugs. Is it because I am using the daily builds ? Some new features can only be used after hours of trial and error.

I just updated to OS 13.1 max os.
Since then I get in the finder contant messages/notifications that ula is running in the background. Unworkable really.
I uninstalled Chaos ula and the problem was gone. No idea what ula does though.

This is clearly a bug that is new and happens with the latest Mac OS 13.1 on my Mac Studio Ultra.

[C4D] Daily Builds / displacement no longer works
« on: 2022-12-15, 12:34:17 »
I have a big problem with setting displacement. If I check displacement I get a black preview and the scene becomes very slow. Unworkable really.
I have relinked the texture maps and it seemed to work again but after a few edits all went black again. Deleted the material with the displacement and got the same problem again.
The materials with dispacement from the Chaos material library give the same problem.

Something else as well, when I press render in the Corona VFB window the C4D picture viewer opens and no render is starting.

Is there a way to easily go back to version 9 ?  I am in the middle of a small project and would love to get back to work.

Any help apreciated

[C4D] Bug Reporting / Corona VFB can not zoom out.
« on: 2022-11-21, 00:55:41 »
Hi, in the current daily build of CR I can not use the zoom in or out buttons after a while. Sometimes the functionality comes back starting a new render but often the buttons do not work.

I am just wondering if there is anybody here who has experience with GPU Octane and or Redshift but is also using Coronarender. How about interactive rendering, speed to first pixel and the overall workflow advantages if there are any.
I noticed that most have years of experience with one render engine or another and often do not want to change. But I am constantly checking out what I might do next. Unreal, GPU or just stick to what I know (C4D Corona Mac). Maybe in the end there is nothing much to gain changing from one fast system to another. As Johan Cruijff used to say, every disadvantage has its advantage.

[C4D] General Discussion / How to use Chaos Scans
« on: 2022-10-24, 19:55:44 »
I am probably overlooking something but I don't see any way to use Chaos Scans. I can't buy or try it since I already have a premium subscription and I do not see any link anywhere to scans libraries.
Is this a feature not yet released ?

BTW, I am feeling pressure here at the office why I need an additional 1000 a year for C4D & CR when others here are having a ball with Unreal Engine 5 or Blender for free.... I keep telling its a quality thing you can't have for free but I am beginning to loose ground....

C4D crashes at CR rendering when I use a downloaded quixel decall. This is because these decalls are exported by Bridge as standard C4D material (C4D R26, C4D 2023 is not yet supported by Quixel).

Easy to solve by converting the scene to CR materials incl. the decalls. But at times I forget to do so and then the scene keeps crashing at render.

[C4D] General Discussion / edge trimmer & texture scattering
« on: 2022-10-11, 18:03:38 »
I tested the edge trimmer & texture scattering features in the daily build v9 rc2.
Really fantastic results. Tx Chaos. I now can hardly understand how I did without.
Can I also use vertex maps somehow or is it texture map based only ?

See attachment with both features set. Its actually rather easy to set the edge trimmer for all textures in one go by selecting them all and set the opacity map to edge trimmer. Super easy but a bit hard to find without a manual. Can this be just a checkbox in Chaos scatter ?

[C4D] I need help! / Edge trimmer how ?
« on: 2022-10-03, 00:59:20 »
Added support for edge trimming in Chaos Scatter using new Scater Edge Trimming shader
Seems very useful.
Was wondering how this works. Could not find it in the chaos scatter.
latest build, osx Mac m1

Bitmaps in the Corona render materials do not copy paste from one file to another. Once copied the materials show up black in the preview and model views. Also these bitmaps do not copy into the the asset browser where the previews are also rendered black.
We had this problem before I think a while back.
When I use the project asset inspector I can relink the materials but they stay black. When i edit the material and click on bitmap for a colour the right map is shown but at render or in the preview it stays black. Only when I manually open the bitmap and re-assign it the material is good again. Need to do this for all assigned bitmaps in the material.
It does not always happen but some materials are hard to work with because of this.
It happened when using a Maxtree asset and copied the asset to a different location on my hard disk. Then I relinked all bitmaps and it looks all right. I can open the Maxtree asset in C4D and it renders fine. But when I copy this asset to another open file the above mentioned happens.

Does the latest build v9 work with the latest release of C4D 2023 ?

[C4D] I need help! / Daily builds download problem
« on: 2022-09-04, 00:09:31 »
Hi I tried to download the latest daily build but the download stalls. First time that happens to me.
The file downloads but it remains a .download file that can not be openend. I checked the package contents and there it looks ok but also the installer does not start.

OSX 12.5.1
Mac Studio Ultra

I wanted to create a decall with a material that only gives a displacement or bump. Is it possible in Coronarender to create a material like that. So no other shader effects then bump or displacement ?

Any help appreciated.
