[C4D] I need help! / Rendering dust cloud as seperate pass
« on: 2020-12-27, 17:34:40 »
Hi,
I’m working on an animation and need to render out a separate pass for the dust cloud behind the truck.
Dust cloud is a simple emitter spitting out spheres with a volume mat applied.
Can’t find a way to render this in one go. When using the volumetrics pass, it includes the haze object I setup for the mountains in the back and they unfortunately overlap.
What is the best way to separate the dust for color correction in AE?

Also, is there a better way to create a more realistic dust trail, without expensive plugins that are not even supported yet?
Right now it looks more like a cybertruck diesel with a broken exhaust.

Thanks for your help!

Hi all,
I’m trying to masked out areas with a material on a plane that renders transparent but shows up in mask passes. This is for these situations where you need to mask everything behind an open window/ door etc.
Sure, I could render a second time, only for the masks, but I need this for the times when your deadline is at 6pm and you stop your render at 5:59… sounds familiar?
The only “weird” workaround I could find is to use Refraction / Thin (no refraction) and Reflection black value set to 0.1%.
Using no Reflection and the mask wouldn’t render at all.
While this workaround appears “invisible” in the rendered image, it technically still needs to calculate reflections that add to render time.
I tried many other things before that didn’t work. For example Comp tag “Seen by cam” unchecked / “visible in mask” visible.
Or, put the plane (not seen by cam / mask visible) in the multi pass “include selection”

Do you know of a better way to do this? Please let me know.
Thanks.

Saving the UHD cache to a “cache” folder in the project directory that can be seen and loaded by all nodes.
This would also help in mixed OS environments where a absolute path just won’t work.

Just like working with ies files in TR got so much easier, after you implemented the ies folder
In the project directory.

[C4D] I need help! / Corona material display in viewport
« on: 2019-10-05, 21:15:33 »
Hi all,
I was wondering if it’s possible to turn off the display of certain materials in the viewport.
To make it more clear what I mean, I’m currently working on some car models adding water spots, dirt etc. “above” the car paint.
These imperfections are basically just a color in diffuse and dirt texture in opacity.
Now, in the viewport all cars display the top most material in the stack and all look the same.
Is there a way to just display the car paint material, make the dirt layer invisible?
FYI: I’m not using IR, so no need to mention it.

While we are here, is it on the Corona roadmap to make the display of Corona mats in the viewport better than it currently is?
Metal, glass etc showing up as pure black in the viewport.
I have seen the standard response of “use IR” for material display, but that is not an option for everyone.

[C4D] Bug Reporting / Render region issues
« on: 2019-06-18, 17:34:24 »
MacOS 10.13.6 / C4D Studio R18.057 / Corona Version: 4.0 (core 4)

1. The set render region disappears after starting new render regardless if region mode is active or inactive.

Expected behavior:
Like in previous versions, the render region marquee stays active between renders.

2. Render region marquee ignored while Team Rendering.

[C4D] General Discussion / Volume Material - Inside Mode
« on: 2019-06-12, 18:28:15 »
Hi all,
can someone please shine a bright light on the “inside mode” feature in volume materials. Yes, pun intended.
It’s not clear to me how this feature is supposed to work and can’t find any info about it.
In my test, I can’t see a difference between ‘on surface” and “inside mode”.

When installing Corona on macOS, I try to deselect LUT and IES in the “Customize” section.
It won’t let me deselect both.
I really don’t want these .ies files and I only use 1 lut and don’t want this annoyingly long list
of luts that, by the way, are not in alphabetical order in the VFB
Of course I can delete all files after installation, but if there is no technical reason for it to be installed in the first place, would be great if this can be fixed.

MacOS 10.13.6 / C4D Studio R18.057 / Version: 3 hotfix 1 (core 3) Jan 18 2019 18:43:49

I don’t wanna beat a dead horse here, but I’m still getting random TR client disconnects that makes Team Render highly unreliable.
Not sure how much this is a C4D TR rather than a Corona issue.
I saw on the trello board that “Team render stability improvements” are planned for V.4
Will the “com error” be addressed that causes frame sync to fail?
Once I finish my current job, will install V.4 daily and check if stability has improved.

To recreate this error, almost any scene will do, just setting the render res high enough.
In my case rendering a 6k image will trigger client disconnects.

Some FYI”s
- Network: 1Gb LAN, Jumbo frames enabled in the entire chain.[/li][/list]
- Server/clients all macs
- Random clients at random times disconnects.
- CoronaTR manual settings:
 Tried many different combinations 10s-20s / 50MB, 75MB,100MB, 200MB all combinations had disconnects
- I have the 1WS/3nodes license - disconnects if I use 1 or all 3 nodes.
- Adding clients over time, to possibly not have them all send data at the same time, does not make a difference and shouldn't with just 3 nodes.

I noticed all TR consoles always say “rendering pass 2” no matter what actual pass gets rendered.
Could increasing the time between the 7 retries help?

MacOs 10.13.6 / C4D Studio R18.057 / Version: 3.0 (core 3)

Not sure if this a known issue, since it never worked (for me).
Note: This is only in TR mode, single machine render region works flawless.

I can draw a  “region” marque in VFB, but it continues to render the entire image.
Same, if the region is already set in VFB before hitting “Team render to PV”

What does work is to set “Render Region” in the render setting > output tab.
Of course that’s a static selection and can’t be changed while rendering.

Not a high priority since there is a workaround, but do you guys have any plans to make the “Corona render region” work in TR mode?

[C4D] Bug Reporting / Can’t open CXR in CIE 3
« on: 2019-01-08, 16:09:53 »
MacOS 10.13.6 / C4D Studio R18.057 / Corona 3.0 stable

Get “Unexpected attribute type” with any .cxr I try.
The last version that worked for me was Beta 2 stable.

I  just realized that "CXR saving in picture viewer" disappeared from the trello board
I didn't yet install/activate my Corona 3 final, but wonder if it made it into this release.
It used to be on the roadmap for C 3, but now it's not mentioned anymore.

The ability to select CXR in render settings is such an important feature for users that send jobs to render farms and need to get a .cxr file back .

Edit:
Oh no, it didn't disappear, it was moved to the "big ideas" pile.... Sorry, missed that.
Does that mean it turned into a big "maybe not"?

Does anybody have an idea for a workaround if you need a .cxr file from a render farm?

[C4D] General Discussion / Your experience with teamrender
« on: 2018-11-07, 21:01:39 »
Hi,
I’m currently using Corona version: B2 on mac R18 on server and client.
I’m testing a scene that takes 39:28 min to render to noise level 5% on my main machine.
When adding 1 node in teamrender the render time goes to 29:29 min.
I didn’t expect render times to be cut in half, but definitely better than what I get.
Corona render settings “TR” is set to automatic. Network: wired 1 gigabit LAN.

I plan to use 1 corona license with 3 nodes (if that’s what we’ll get when released)
and send larger jobs that require faster turnaround / more compute power to a render farm. I only do still images.
If the LAN is a bottleneck, would upgrading to a 10 gigabit make sense?
I’m not even sure the gigabit is saturated as it is.

What’s your experience regarding TR?
Any tips on how to minimize overhead / get faster renderings?
How well do additional nodes scale?

Thanks.

Version: B2 daily May 30 2018 (core 2 DailyBuild May 30 2018) (same version on all nodes)
Cinema version: CINEMA 4D Studio R18.057
OS: Mac OSX 10.10.5

Hi all,
I'm using a IES file located in the "ies" folder, inside the project folder.
The IES renders fine when "render to picture viewer" on my main machine, but does not render when "team render to PV". Just the corona light renders without using the ies file.
I also tried the IES file placed in the "tex" folder (of course updated the path in corona light).
The ies only renders if the path looks like this "./filename.ies"  or "./ies/filename.ies"
If the dot in front is removed  "/filename.ies" or just "filename.ies" the light will not render.
I would assume with "filename.ies" c4d finds the file in the "tex" folder, but that's not the case.

It might be related to how c4d on mac os handles relative paths?

As a workaround I tried to use the UHD cache saved from "render to pv"
and load the file when using team render without success.
I looks like Corona still needs the ies file to calculate the light.

Can other mac c4d users confirm if ies lights work in team render.
Any ideas for a workaround?

Thank you.
