That is easy to say about your work, mrittman,

Your passion for details and quality shows, and that is motivational.

Enjoy!

Thank you very much, mrittman, for your reply.

I hope you will have as much (or more) success with your new project as you had a while ago!

Cheers

Hi mrittman,

You're very welcome!

Please keep in mind that many simulation parts of the application work mainly on the Graphic Card. The preview that you get there is what it is, a preview.
In the end, the rendering is the key, and the preview should not be the only guidance for all the project work.

Please check your render settings to switch to Redshift; it is part of Cinema 4D. The Redshift subscription for Cinema 4D would enable more render clients in a render farm.

Please use images of 500 pixels in height; then it should work.
Anything else, please, as Dropbox, Google, WeTransfer, Adobe, or Apple. (No upload of Zip/rar, etc., nor tiny URL, and please no HTML URL wrapper) Based on security, no exception.

All the best

Hi mrittman,

Please have a look here:
https://help.maxon.net/c4d/2025/en-us/Default.htm#html/COM_REDSHIFT3D_REDSHIFT4C4D_NODES_CORE_VOLUME-COM_REDSHIFT3D_REDSHIFT4C4D_NODES_CORE_VOLUME_GROUP_9.html#COM_REDSHIFT3D_REDSHIFT4C4D_NODES_CORE_VOLUME_DENSITY_NEW_MAX

The best way would be to ask EJ if the project file is available. As you are not new to 3D, exploring other files might be of more value than getting a "do that" suggestion.

Having said that, please look below; I have changed the Voxel Size in one case (to address your point about it) and the parameter of the Pyro Materials under the Advanced tab for that Pyro Node, which has a much stronger effect. However, finding a balance that fits your art-directing target is key. Please note that changing the Voxel size requires a recalculation. Just changing the value will not change it on the fly. With a cache of the scene, you can upres.

Is that helping?

As a side note, please look into the Asset Browser; based on comments during our shows, artists have found answers to specific questions here.

All the best

Thank you very much for your feedback, eclipse-planet.

Sounds good!

My best wishes for your project.

Hi guard-field,

You do not describe a site issue here, nor do I see a request about solving access problems.

Please do not use this forum for anything other than the intended purpose. Thank you.

This forum does, by default, not answer Software questions.

If you post in the correct forum, please share a c4d file (<= 1MB) not zipped/rar.etc. (Just the needed parts in the file.
If larger, only DropBox, Google, Adobe, Wetransfer, or Apple cloud services will be used for security purposes, no zip, no rear, etc, no tiny URL, nor word-based Hyperlinks. Thank you.

All the best

Thanks for your patience, RemoGambacciani,

How about this option:

Hi appointment-insect,

Just a little feedback:
IT told me that the screen capture is very helpful.

I will update with more as I get new information.

Thanks for the reply, RemoGambacchiani.

Yes, this was even asked a few times during the "Ask The Trainer" live show.

Anyway, please try to minimize the geometry and let Redshift tessellate the results, which might be faster…

As an alternative, could a plane with a texture/alpha help here out?

Cheers

Hi RemoGambacciani,

A blend along a Spline is not given as a spline rendering, AFAIK.

I checked again to see if any Hair combination might do… but sorry, no luck.

As in the other thread, a Sweep and Vertex-Color Tag are needed.

Please add your request to render Spline Vertex maps here (Share Your Ideas):

Thanks for the ticket number, Dutchbird.

I surely understand the frustration. I try to avoid having that social media echo chamber syndrome. Any long-term user like you knows problems happen and typically get sorted out. All of them, sadly not. But I'm sure OCIO as a framework and ACES as a Color Management system will have attention.

The color shifts happen mostly based on color and gamut compression, when large color spaces and high dynamics move into small formats, like REC 709 or sRGB. This will not change; with any new ACES version, new shifts will happen going into smaller formats.

One reason is that the renderings have no IDT (Input Device Transform), and if everyone has his/her outcome from a render, then the Tonmapping and Gamutcompression for smaller formats will have very different outcomes. Think of an S-Curve in Photoshop; while moving the underlying content up and down in exposure, the midtones might move closer to the shoulder or the toe of the S curve, which will change things. This is, in a nutshell, why the REC709 or sRGB RRT/ODT has shifted.

New solutions have been announced, and one of my many ACES trainings (since 2012, I have taken ACES classes all over the place) showed last year a new way to handle this. (color.training is the URL; I'm an alumnus of the Color Academy for Professional Colorists) Dado, the Color Academy owner, trained us with these new tools back then.

In short, things will continue to change. Hence, renderings should be stored in ACES AP-0 and 32bit/channel float.)

All the best

Thanks for your patience with this appointment-insect.

The limitation with compression is set here, as it is public, and I can control any compressed content constantly if the content is swapped out and replaced with something harmful. I try to keep it safe for everyone here, and the sad thing is, of course, it takes time for anyone who just wants to create.
How the tech support handles it is not for me to publish it.

My best wishes

Hi there,

I can understand your frustration. But please keep it to facts and don't use this forum here for emotional downloads. Thank you.

Please share your findings with the Tech Support here:

Hi RemoGambacciani,

Here is my workaround, with a Linear Field for the colorization.

About the Splines and Deformation
The deformation works with the point position relative to the Object axis.
In other words, the points stay relatively close to the object axis if the object is moved.
Examples
CV4_2025_drs_25_MOdd_01.c4d
CV4_2025_drs_25_MOdd_11.c4d

Please let me know if that works for you.

Cheers

Thank you very much for the screen capture, appointment insect!
I will forward the video to IT.

I wrote last night to IT, and they have looked into it.

The zip files I do not open, sorry, that is protocol here. However, thanks for using Google Cloud services, which is one of the few services we selected here. Yes, it is all about security these days… sorry about the zip stuff (rar and others are the same, no compression) for uploaded files.

Fingers crossed we get this sorted out.

Thanks again for the kind words.

You have personal data in the screen capture, I would take it offline.

Cheers

All the best

Hi Dutchbird,

Thanks for asking.

Let us start with the Banking.
If there is any chance that the points of a spline can produce a "plane-like orientation, then that plane defines the orientation of the Profile used.
In return, each point counts if a plane can be established at all.

Moving a single point in that case will change anything. Based on my experience teaching it, there is the most confusion, especially when the spline is not animated to show the effect.

Have a look at the end of the spline Left upper in the perspective view. Press play.
CV4_2025_drs_25_MOsb_01.c4d
The profile orientation changes.

If there is no plane, meaning the points are all over the place, the banking option that relies on such a virtual plane can be shut off. Which often leads to a horrible result.

How that can be solved most of the time is done with Rails, who work like a target but along a spline in relation to the main path.
CV4_2025_drs_25_MOsr_01.c4d
Parallel moves, ignores all of that and keeps the Profile in the same orientation along the path.

My suggestion is to mess with the settings of the two files, as I hope they provide some more clarity if the checkboxes of the Sweep are explored.

Let me know if you have more questions.

Cheers

Hi appointment-insect,

I'm on the West Coast and can't reproduce this problem. I will point IT to this message here.

I know this is frustrating and surely nothing we like at all. Sorry about this.

I hope it can be cleared ASAP.

All the best.

Hi eclipse-planet,

What formula would you like to see for binary representation of clones? Typing 0 and 1 perhaps works more than the "paint" selection set on a clone setup.

In short, I need more details and more information.

Examples
CV4_2025_drs_25_MGfs_01.c4d
CV4_2025_drs_25_MGfs_11.c4d

How about a texture as a "field" in an Effector.

Anything Python is discussed in the Developer Café. Here, we do not exchange code snippets for security reasons, with no exceptions.
https://developers.maxon.net/forum/
I assume the simplest is to feed a List and read it ou, but that is for the Developer Café

All the best

Thanks for the reply, Dutchbird,

Please let me know how it goes.

Have you considered a texture instead?

Cheers

Hi Dutchbird,

Thanks for the file.

Would this work for you?
CV4_2025_drs_25_MOrb_01.c4d

I used your Spline, created a copy, and moved the copy.
Then, I applied the Loft to get the main shape done.

For more adjustments, the Remesh works well, and the SSD smoothes the shape a little bit.

Perhaps consider the Spline to Chamfer and provide some Bevels on the Frame tubes.

All the best
