[C4D] I need help! / TEAM RENDERING ISSUE - PLEASE HELP!

« on: 2025-07-08, 09:17:24 »

Hello. I have a Mac Studio M1 Ultra as my workstation and I also have a Threadripper 2990WX as a render node. I'm trying to send jobs over to it and set it rendering but I'm getting out-of-memory errors. Even simple files. I have 128GB RAM in there and there's plenty of room on the internal drives so I'm not sure what's going on. I can render a non-corona scene that's very complicated in comparison - no problem. Therefore, I'm assuming it's a Corona issue.

Does anyone have any ideas on this?
Thanks in advance...

[C4D] I need help! / Tones on my materials are 'washed out' - can someone help me?!

« on: 2025-06-10, 14:15:38 »

Hello
I do retail displays. My clients are getting more and more fussy. A recent issue I've come across is the fine tones (especially skin) in some of my visuals is losing colour and getting bleached out. I've tried a few things and I'm hoping someone who knows more about materials (I didn't actually 'learn' Corona - I just jumped right in) can help? If I darken the scene to stop the bleaching it makes all my white things go grey, and it still loses some of the saturation in the image. I've attached an actual 3D file and a render next to the supplied artwork so you can see the difference I'm getting. Any advice welcomed!

PS - This promotion is old so there's no NDA issues here.
PPS - You will need to load in a HDRI as mine is too big. It's called "Underground Studio.hdr" in case anyone else has it.. I can send it to someone if needed.

[C4D] I need help! / Cylindrical Displacement on a Plastic Lid

« on: 2025-04-03, 08:11:10 »

Wondering if anyone can help me. I've always had trouble with this and I'm sure there's a way to sort this easily.

I have to model the lid of a spray. The lid has an embossed logo. Goes in about 1mm. With a decal it'd be no problem, I'd make a displacement material then map it to the decal and have it only affect the displacement. BUT I can't wrap a decal onto a cylinder - can I?

So, I'm assuming I have to go with a Corona material.
My displacement map is greyscale, goes from black to white.
When I map it onto the material I do it this way.
I duplicate the material, add a displacement channel, then drop the new material onto the model on top of the 'base' material. Because all other elements are identical, it's seamless. Well, it should be, but there's a square line around the edge of where the material is. I've checked the black and it's 100%.

Does anyone know of a way to fix this as I've fiddled around a fair bit and it's still slightly visible whatever I do.

I'm sure there's an easy way of doing this but I don't have time to search all over the place and be testing so I thought I'd ask the experts!

Thanks in advance

[C4D] General Discussion / Amazon AWS Render Nodes. Has anyone done this?

« on: 2025-01-15, 16:56:53 »

Hi all. I've gone through the painstaking effort of creating an Amazon AWS render node. However, upon remotely accessing the node I'm finding it hard to install the software (C4D to start with, not tried to get Corona on yet).
I was just wondering what the licencing thing would be? Perhaps I just install the software as a team render node?
Can anyone advise? I might have to upgrade my licence, yes?

[C4D] General Discussion / Benchmark Score for an Apple 10 Core M4 vs Apple Studio Pro M1 Ultra

« on: 2025-01-15, 11:05:01 »

Hi all. Wondering if anyone has any benchmark scores for the base Apple M4 which at the moment is the 10-Core CPU / 10-Core GPU / 16Gb Ram?
Just seen I can get one for £533, was considering using it as a render node. But only if it's worthwhile...

[C4D] I need help! / COSMOS BROWSER HAS DECIDED TO STOP WORKING. HELP PLEASE>

« on: 2024-09-25, 11:22:48 »

Hello. I've started getting this error message as of a couple of days ago when trying to open the cosmos browser.
Running a Mac Studio M1 Ultra with Cinema 4D 2024.4.1 and Corona 12
Any ideas?

Also, my cinema 4D crashes at least 8 times a day when loading images into my project asset inspector. I've noticed that the HDRI image I have loaded into the Corona Sky object for illumination needs to be reloaded in the actual object manager or it'll crash pretty much every single time. Also, if I've re-linked everything using the project asset manager and press render then try and save then close quickly afterwards about 25% of the time it'll crash cinema 4D too. This, as you can imagine, is frustrating beyond belief and expensive for my company's efficiency. Is this a common thing? If so, is there anything I can do to solve it?

[C4D] I need help! / Help with refraction please

« on: 2024-05-08, 11:08:37 »

hello. on this issue, I have some bell jars. when I place the bell jar over the item the refraction is CRAZY. It looks like the whole thing is full of water or something. I've attached a screenshot and a rudimentary file. Can someone help? You'll have to drop an HRDI into the scene to light it perhaps.... (mine's too big).

[C4D] I need help! / Translucency on Mult-Pass Masks

« on: 2024-04-25, 12:00:59 »

Hi. I have a quick query.
A lot of the things I do are retail concepts. A lot of these feature a clear acrylic case/tank/box to stop theft. I'm sure you know what I'm talking about.
Sometimes (more often than not) the client would like to see the display on a completely white page.
So, if I do this and set a muti-pass mask it'll do a solid block alpha channel of the whole unit. Whatever was behind the clear acrylic tank/case in the original render will be shown.
Is there a way of creating a more 'in depth' mask that captures the translucency of the material so I can overlay the visual on to any background?
See below for an image of the results I'm getting at the moment - branding and product blurred out because of NDA's etc...

A workaround I can do at the moment is put a white box right behind the boxes but it's not ideal!

[C4D] I need help! / Instances with Decals. Problem

« on: 2024-04-23, 12:01:17 »

Hello. I've recently noticed that when I have an object that involves a decal if I make an instance of it, the decal will not render. it's clearly in the structure of the model and it's even in the wireframe preview but it doesn't render out.

Is this a known bug? Am I doing something wrong?

See below for screenshots of details.

[C4D] I need help! / Copying and Pasting Objects messes up the materials. Help!

« on: 2024-04-10, 18:57:39 »

Hello.
I have different scenes which quite often have the same items in them. Therefore, I'll tend to copy the object from one scene, then open the other, then paste it. When I do this, the materials go bananas more often than not. Sometimes It'll just do straight swaps of my base colour materials, sometimes it'll just switch off the transparancy. Sometimes the translucency of my liquids and stuff will be completely wrong.

I've tried saving objects out, then merging them into my new scene (which is an absolute pain in the arse anyway) but its still goes wrong.

Is this a known bug? Is there a fix? It's happening to my colleague too so I know it's not just me...

[C4D] I need help! / Working with metal materials within C4D. All black. Is there a workaround?

« on: 2024-03-05, 14:07:19 »

Hi All.
I work a lot with metal and glass materials. Mainly in the fragrance industry.
Is there a way to 'see' the colours and materials a little better in the working window? It's quite frustrating when literally everything in my entire scene is black....!
Wondering if there's a way I can force a colour to at least display so I can see what's what when working...?
Thanks in advance....

[C4D] I need help! / Shadowcatcher

« on: 2024-01-31, 14:27:30 »

Hello. I'm trying to work with the shadowcatcher material but my shadows are coming out grainy. I've tried fiddling with pretty much every setting I can see. If I render the scene onto a white 'floor' the shadows look absolutely fine. If I use a shadowcatcher then the shadows are very grainy.

Are there any settings I can play with that'll sort this? I have three Corona lights in the scene.

See attached image for two renders. One directly onto white. The other a shadowcatcher material, then with white behind it (in photoshop)
Any help massively appreciated...

[C4D] I need help! / DECALS and Instances

« on: 2024-01-18, 18:57:04 »

Hello
I often create a design concept where I have to show various views of the same item. I will usually create an instance of the object, move and rotate it etc.
Usually when I create the instance - the decal will just go missing. Won't feature on the render.
Can anyone shed any light on this? Is it a glitch/bug?
Any workarounds?
Thanks in advance!

[C4D] I need help! / Material Conversion from 'Standard' to Corona

« on: 2023-12-21, 13:50:31 »

Hi All.
Been given a job where someone's dropped a 'standard' 3D model (with textures) into a Corona scene for me to carry out some amends on. However, all the textures are in 'standard' format and render out very dull.
Is there a way to quickly convert them all to Corona? There's nothing special or anything in there like volumetrics etc.
Surely there's a 'convert to Corona' button somewhere?
:)

[C4D] I need help! / Render Speeds. Tips on Speeding things Up

« on: 2023-11-09, 12:31:06 »

Hi everyone.
We have to churn out a lot of renders here. Are there any tips you people can suggest to help me and my colleagues speed things up at all? Materials / Render settings etc? Other than going out and buying new computers of course...
Any suggestions would be greatly appreciated.
Thanks in advance
