CINEVERSITY

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.

Regarding the error messages, I had asked a while ago if there is a list with error messages or any definition that I can share.
The answer was, if there is a problem, please check with tech support.

Cheers

Hi MV,

Yes, you got that right; the 63 had some unsorted priorities. I left them in as I moved on with 64 to fix those. Sorry if there was any confusion based on my doing.

I'm glad you brought that theme up, as I know the (mostly) where the limits are, but there is, more often than not, a way to make a workaround of some kind that might come close.

The head or the "tool" needs the freedom of 6 axes alone, which is not doable with normal input devices directly and, in that way, hard to direct since I do not have a "Space-Mouse". So the Target-Tag use (as your headline suggested) is a good help.

My best wishes for all the projects you manage at the moment.

You're very welcome, AlexC.

Before I studied architecture, I had three years of training to become a Technical Drawer; to create or read those "blueprints" is second nature to me. Which makes me confident to have shared the fastest way. Thanks for checking this out.

Your intuition about the Arc was not off.
It can be done with an Arc, four of them, but the problem here is that the center point of each Arc is not in the center of the tent. This causes a lot of trial and error, especially since the "blueprint" has no orthogonal view to this quarter arc, like when it lies on the ground to be assembled. The radius of an Arc here is 12.80m-13,50m (+/-) based on taking it from the "blueprint". Using the three orthogonal view (Multi View) re-engineering method is faster and has no guess-part in it. Anyway, your intuition was good.

Enjoy your project

Thank you very much for the feedback, Pim!

Here is a (very) quick fluid example. Needs more work. Increase the mesh resolution (segments) for a finer result.

It needs a little bit of time; render it and use the result perhaps as texture.

Enjoy

Hi Jochen,

Inside Trapcode Particular, you have the following options.

https://help.maxon.net/rg/en-us/?_gl=1156481g_gcl_au*MTE2MDM5OTE4Mi4xNzQ4MDE1ODAz#html/Particles-and-3D/Trapcode%20Particular/visibility.html?TocPath=Particles%2520and%25203D%257CTrapcode%2520Particular%257C_____57

Besides that:
If I understand your question correctly, if you like to use a mask, set up a solid on top of the Layer that has Trapcode Particular and use in that new Layer any mask you like to have, then connect it to the Particular Layer, (Track Matte)
Alternatively, Pre-Compose it, then use a mask in the new Composition.

Please let me know if I got your question correctly.

All the best

Hi OlcayKayihan,

Please find a list from June 10th here

Fingers crossed, this is fixed for you in no time.

merged object.

So far, I can see that it is a Python script option. Since this forum is code-free, for security reasons, please check with the experts over in the Developer forum.
https://developers.maxon.net/forum/

I will write a report about this as a request.

Fingers crossed, someone can help you.

There are some scripts available (google it), but please read through them carefully, as Python is not without risks.

All the best

Thank you very much for the reply, Capprim.

I'm glad that works for you.

My best wishes for your project.

Thank you very much, Dutchbird.

The interesting thing is that I can't reproduce that here, but I see a red-marked Field Object in your file that vanishes, and then I get an error. Metal Leak. So, I'm interested what is going on here.

Hence why I ask. More work on my side to figure that out.

I'm glad it works on your side.

All the best

You're very welcome, AlexC.

My best wishes for your project!

Hi tie-version,

Images taller than 500 pixels will not show up.
What I would need is a project file reduced to the problem. If below 1MB, it can be attached here as a c4d file.
For security reasons, zip (or any compressed file) is disabled.
Cinema 4D as c4d files and max 1MB work. If larger, please use Dropbox, WeTransfer, Apple, Adobe, or Google Cloud services only. Please use no zip, rar, etc., during upload, and paste the URL for the file in the text; do not include an HTML wrapper or a Tiny URL. Thank you, and I apologize for the lengthy text.

A first-hand exploration/share of Toon Lines is done by Adrian, part of the Redshift team.

The Softbody takes over, and the Skin Deformer is no longer in use. If you take other Simulations, the result is different, but the Hierarchy drives the trouble.

My suggestion #1, use a PoseMorph.

Here, you can use a Collision Deformer result, which can be applied after disabling the Skin deformer. Which might lead to a T-Pose. So, you might want to take a copy and, in the sitting position, set the Binding Pose to new.

Now switch the Skin Deformer off and apply the Collision Deformer to the Character. (If you like to show some impact on Character.) The seat must be positioned within the Collision field of the Deformer.

If the deformation looks right, use the Object Manager > Object > Current State to Object (CSTO) to create a deformed copy. If needed, use the Magnet or Iron Tool to shape the Character's details that come in contact with the chair.

Now, you can switch off the Collision Deformer or delete it. The result of the CSTO can now be used in a PoseMorph. Apply the PoseMorph to the Character mesh and set it to Point mode.

Drag the CSTO result into the field of the Poses. I suggest to use "no" for the Alert. Set the Pose Morph to animation and the Pose slider to zero. Switch the Skin Deformer back on.

Now, you can add the impact of the chair to the Character by animating or just adjusting the slider.
Example:
CV4_2025_drs_25_CAdf_01.c4d

My suggestion #2: Do the opposite. Deform the Chair Cushion. Typically, the Barcelona Chair is not very soft, but the impact might be visible.
That means the Character becomes the Collision, and the Chair Cushion becomes the Collision Deformer. Explore the Object>Restore Slider value of the Collision Deformer.
Example:
CV4_2025_drs_25_ANdf_01.c4d

Or, a suggestion combining #1 and #2: Of course, for a close-up, perhaps a little bit of example 1 and much more of example 2 might be a good balance. For the quick Solution, use a CSTO of the cushion and sculpt the contact area into the mesh. For animation, use the PoseMorph options. I leave that to you to explore, no example.

All the best

Hi relationship-developement,

This is difficult to tell from an image. I work from Project files. Those work or not. Images typically require lots of questions* and perhaps even more questions.

*Example (not that I ask for answers to that; I need a file): Is the scale matching the Simulation scale. Are the iterations (etc.) enough to handle it, the distance (Search Radius), and the collision Shapes. Have you tried to use simplified tires? What is the Draw Mode telling you? All of those questions can be avoided with a file.

I can take a look at it., but if you share a file (and it looks larger than 1MB, then please only use DropBox, Wetransfer, Apple, Adobe, or Google Cloud services. Please upload the file uncompressed (no zip and surely not rar). Also, share the URL as is, not shortened or in an HTML wrapper. Just paste in the text. Sorry for the long request text, but safety first.

All the best

Hi hurt-valuable,

Why not use PolyFX?

Please have a look at the example below. Place your image sequence in the material.

Is this working for you?

Hi Dave,

Thanks for the reply. It sounds easy for you to decide then. 🙂

As a side note, if you need some versions back, keep an eye on this link.
