Have a great Holiday as well, entry-newspaper. Thank you!

Great you found it.

My best wishes for your project.

Hi entry-newspaper,

Is this what you are looking for

I hope that helps and sorry to be short, I have some time off and back on July 07th.

Hi Jan,

Since my animation does exactly that, with fewer spline/times, since it is an example, you just try to avoid setting 25 (24+1) keyframes? I read from your description that all the changes of the 187 artists are moving forward in sync, correct? This is meant as a question to understand it better. Segments are unclear in your description; from one point to the next is not considered a segment. Is that where we get stuck?

Perhaps integrate it in your Python script via frame. BTW, this is a Python-free forum, as we have a developer forum for that. Any code shared here will be deleted, as I can't check if someone changed the code later on and provided male ware like it was found in assets for a different software lately.

If you can generate all Splines in their final length, with 25 points (O-24): Current State To Object, and then use it in the file below instead of Spline_187.

This file has zero keyframes. 187 segments, each 25 points
cv4_2025_drs_25_ANsp_11.c4d

In case you need to keep 187 single Spline:
cv4_2025_drs_25_ANsp_21.c4d

Since I have Friday time off until Jul 7th, perhaps check in one Thursday for Ask The Trainer and explore with Noseman how to do that with Scene Nodes.

I will be around to answer a few questions, but I surely need time to recharge. Maxon has work ethics, and I'm not supposed to ignore those.

P.S.: here is a Freeze 3D View Workflow - but as patch.
I have removed the save and load parts, as I think they are clear.

Hi Bruce,

From the perspective where you can see the black artifacts, create a Freeze 3D View. The image in Photoshop should be limited to the problem area of the fix (e.g., Stamp Tool). Leave only the PP Layer in the file, while the layer hols strictly transparency and only in the area of the problem content.

Save it, merge it apply it. The black seam might come from the Black background that the "PP All Layer" had, which should not be part of the Merge file.

Is that working for you?

Cheers

Thank you, Pim.

I deeply love to do that! Supporting many projects and productions and answering questions of any kind. I am the one who has to say thank you, as it allowed me to grow and get involved in so many ideas and creative projects.

Your project so far has been colorful in many ways; it's fun to see that growing.

Enjoy!

Thank you, Pim,

Yes, I'm ready to slow down for 9 days, as I was searching for an Object. It would have clicked with Particle Blend Modifier.

Even the Documentation's URL has an Object in the title,
But I was searching in the Redshift Documentation based on all the Nodes questions and color questions. Sorry about that, my fault.

Here is the Manual page, which I think has a lot to offer:

Thanks for your patience! I will check in next week, but I try to keep it short; typically, that is the slowest week of the year, hence my timing.

Enjoy

Off Topic

No problem, hard to tell sometimes, Pim.

The readability is easier for anyone when follow-ups are in a new thread, as they might come back to the initial question. Sometimes it is one combined them, sometimes not. Separating makes it also easier to link to it.

It is not a pleasure to bother you with that. So: Sorry. But I know how often I have gotten feedback about the noisy threads in the first years of the 21+ years I've been supporting Cinema 4D fora.

Enjoy your weekend

Hi Bruce,

Thanks for the reply,
Sorry, I can't reproduce the black artifact. Some wild guesses...

Can you reduce the PSD file to the PP layer, drag it out of the Folder then delete the Folder with the mask?

Perhaps setting the Freezing 3D View to 2x of 4x (scale) might limit the effect.

Also, for the "PP All Layers", try to delete it before saving the PSD. Is that helping?

All the best

Hi Pim,

Mixing Color in your setup is like layering "Gels". With this, the first one works like a filter. For example, if you have a red filter and a cyan (second) filter, they will block light simply based on frequencies.
However, what is a pure green and a Pure red? If you use an sRGB colorspace, you get something, but not a full saturated color like green or red. Yes, I know, everyone will say, but I can see it on my screen. Well, typically not. Which is a longer story. But a pure red in sRGB is in sRGB 8/bit values 255; 0; 0, but that is the smallest colorspace possible and never should be used in professional pipelines. This means if I take these 8/bit values, the red in ACES 2065-1 would be 112; 23; 4. This means not even a fraction of that saturation that the sRGB or even P3 screen shows. So, a red would not block green fully as it has green in it. So, mixing colors is a little bit more complex. (So, using ACES 2065-1 all the way, well, yes and no. Typically, a standard screen can't handle the colors, some Applications have problems (hence the ACEScg limitations), and the need for Gamut Compression and, later on, Ton-mapping changes the colors to fit into a smaller space, that many people answer with creative (to say it kindly) workarounds. In other words, it is a theme that takes a longer time to dive fully into it. I can share some book tips, or (my favorite) as I'm an Alumni of the Color Academy for professional Colorists, Los Angeles, to invest a year in their program.

But well, if the light goes through those, and both have perhaps a white background, the light would be a colorful ( or less so) shadow. In any way, this shadow moves back through both filters and is affected again. Like every color filter is just a partial ND filter. Note: colors are not real; we produce them inside of our brain. Light has only frequencies, which different cones can receive more or less, and then Color is created later. In terms of filter, some frequencies get more or less blocked, others don't. Why do I explain all of that? Because feeding Color into the Opacity means to create a filter. While red will create a Cyan-looking result. Think of the red channel, if red it the color resulting from RGB as a channel that shows white. Hence Blue and Green are black, resulting in Cyan as transparency. If inverted only red is a black channel, and the result looks like red gel filter.

In your scene, there is the top layer set to be a filter, and using the colors to drive the Opacity means the red is more transparent. I would suggest here a neutral gray, perhaps 70%. If the colors have to drive this, use an Invert to get the proper colors of the '70s.

Tip: Enabling the View - Options> HQ Noise might help to get improved previews (not related to the Color question)

In short, that was a deep dive for that short question, but I wanted to share more insights into what is going on - instead of just dumping a file and telling you to do this. Which I find always for those themes not adequate. Read it and let it sit for a while; it is not a small subject.

Here is your file back

Hi Pim,

There is, to my knowledge, no Blend Object.

Hi Pim,

The Vertex Attribute Node takes the Vertex Map, either single channel or Color/alpha from the object. The key concept here is that every point of the object has an ID number; the tag then adds a single value (0-1) to it, or for the Color, even a four-channel value RGB-A. The colors or value of the Vertex maps can be painted or applied with Fields and other options. The Vertex Tag should always get a proper name. Leaving it by default can cause confusion, leading to unwanted results.

The Vertex Attribute Node takes those Point/Vertices values in and interpolates those over the surface. The lower the number of points, the less likely a pleasing result can be expected. Higher values might slow down the processing. Sometimes, baking the data can be beneficial.

The result is, to a certain degree, comparable between a shader and a texture and can be used to drive channels in the materials.

To know which Vertex Tag to use, the Node has an entry field for the name; dragging the tag into will work.

One key feature when using these for anything is that values should be provided in the way they are needed. In short, RGB is not always RGB, which sounds cryptic, but Linear and gamma-encoded values deliver a completely different result if interpreted wrongly.
Color Management is often ignored for these values, and the results might look surprising.

More details are here:

Hi Pim,

Please continue with the new Question in the thread linked above. Thank you.

Cheers

Hi log-story,

Here is a simple start; perhaps that works already for you. The key is that some Spline functions are based on the Points and not their distance among all points.

Your definition of the Splines was 24 points. This will only work if there are no intermediate points. Think of Interpolation Points> Adaptive.

For simplicity, I have created a few Splines and Merged them into one.

Example (Shorter timing than 24 frames, but that is not limitation)
CV4_2025_drs_25_ANsp_01.c4d

Please note the Animation uses no interpolation between Keys, just "Step"; at least, that is what I got from your text.

All the best

Off topic.

Please, again, one theme per thread, it is work to split this, and even more for anyone reading through mixed threads, while perhaps searching close to a deadline for an answer.

Hi Bruce,

If I am not mistaken, you don't get the results from "Freeze 3D View," and that is related, as far as I can tell, if a single click is missing. Hence, I shared a video (a short Demo) above that points to the main critical steps.

If one step is missing, you get the texture instead, not the view. If another step is missing, the Frozen 3D view will not get back to the model.

Please read the post, not the email. I realized last night that I do these steps with muscle memory, and the manual does not have the full process to get a roundtrip established. Again, the 60-second video is a working round trip.

Cheers

Hi archie,

Thank you very much for your feedback, Pim.

Sorry about the errors limitting your production right now.
I hope there is a quick fix for you

Hi Bruce,

Yes, the Projection is always transparent, initially, except for the content painted on it.

If you have a texture, it should appear after using 'Freeze 3D View' and saving it as PSD. Then, after fixing, merge it. However, I do not have R21 here. There were some problems back then, but if that was with R21, I really don't know anymore (I have been using C4D for 28 years, so I don't have all the releases memorized.)
The PP (Projection Painting) needs to receive the new information from the "PP All layer" in the PSD, Merge Texture (C4D), and then it needs to be OK'd to be projected.

Here is a short demo:
https://projectfiles.maxon.net/Cineversity_Forum_Support/2025_CLIPS_DRS/20250627_Freeze3DView_2025-3.mp4
Please test this on a copy, as I can't tell how R21 will do, assuming you have a current OS running.

If it is not working, here are some suggestion, guesses…

For the seams, you can CMD-Click to select the color, then paint the seam newly, either on that layer or in Photoshop. Any change can be done.
Perhaps your project is different, but I have nothing here, nor R21.

If the texture is in an 8-bit color, remapping it after setting the UVs differently can sometimes help. However, remapping is like lens distortion correction; it roughly cuts the quality in half.
https://help.maxon.net/c4d/r21/us/index.html#11664

Another option, and again a guess, perhaps a Camera Projection might help. Render the object from the main view, Luminance channels to get no light into it, Protect the Camera (PSR), and have it as top material. If you have a bump or displacement, I would no longer recommend this approach. No idea if the Color management is game for the setup.

All the best

This post has been edited (video clip), as I continue to search. 12:30 am. Now I call it a day.

P.S.: There is a difference in Preferences> BodyPaint between R21 and 2025.3, please check this. …Include All.
