CINEVERSITY

Thank you for your reply, thorsnuts.

There are many ways; it always depends on what is given.
As mentioned, this is a technique I have shared for around two decades, often used for rollercoaster simulation (parks) or racetracks. With User Data and relative referencing, this tag can be used in many cases without even opening the XPresso editor. To reply to your script idea.

Here is an Alternative

Sometimes, the Surface Deformer works best.

Enjoy your weekend

Hi reward-potato,

I got a reply.

The team pulled file _010. I'm sorry that this caused confusion. I'm sure there was valid concern behind that decision.

If you have any questions, I'm happy to answer them here, whether they are related to the video content or outside of this scope, in the Q&A forum.

All the best

Hi milsy05,

The simples workflow might be this two step process.
Screenshot 2025-04-11 at 9.41.05 PM.jpg

Here is the simplest way to work with textures and two sides while the clones are individually rotated 180º, presenting the "backside" readable.

File 01 is the image production

Preparation, switch off Chamfer, Extrude. Rotate the clones 180º individually so the wrong image is rendered. (the "180º" Plain effector does this)

This image should be supplied as an Emission with a weight of 1.0 and all other channels set to zero.

The Partition Modifier has a gap size of zero for this rendering.

A camera with a focal length of 36 mm centered over the image at the same distance as the width.

The render size equals the ratio of the rectangle up for rendering.

Global illumination is off; it would only take more time.

The wrong image is rendered and swapped out with the correct one.

The Formula in the Polygon Selection is ID>0, allowing it to cover all but the bottom sides.

Leave all the settings safe and use them for additional image productions.
Save now incrementally to get file 02

As file 02 shows, the Extrude and Chamfer are back on, and the Extrude has Create Caps enabled.
The Top and Bot(-tom) files are separate Materials, and one has the Selection Tag with the Formula Filed set to ID>0. This selection Tag is in the Selection field of the Top Material that sits on the right in the Object Manager.

For all minor details, here is the set up of file 01 and 02

Enjoy

Hi entry-newspaper,

Depending on your object's mesh resolution, there can be a lot of data that needs to be processed.

I copied this text from the other reply:
Perhaps the Freeze can store those better if they don't change. In the moment they are stored, the selections can be switched off.
You can check the specific processing time in the
Main Menu> Window> Object Profiler.

I try typically not to guess here, but I'm sure my little system here will behave differently than yours, so any file exchange might result in something that will not help. I know asking questions might waste time on your end, but let me try:
Have you tried to bake those as Alembic files?

Perhaps create an RS Proxy from it

If the draw on the system is very heavy, perhaps explore XRef and the use of a Proxy.

Enjoy your weekend

Hi entry-newspaper,

I'm unaware of a different way to get the data easier or faster into the Vertex Tag.

Perhaps the Freeze can store those better if they don't change. In the moment they are stored, the selections can be switched off.
You can check the specific processing time in the
Main Menu> Window> Object Profiler.

I can't say more since I have zero data about your setup.

If an example is below 1MB, it can be attached here as a c4d file (never use zip, rar, or anything here in the forum.
Given that the file is larger, I will touch only DropBox, Wetransfer, Google, Adobe, or Apple services for security reasons. Please, no tiny Uad, no zip or rar, e.g., for the upload. The URL is just pasted here, not HTML -hidden Hyperlink. Sorry for the long text, it is all about security.

Enjoy you weekend

Thank you very much, Dutchbird,

I will explore this. I will add your observation to my report.

Have a great weekend.

Hi selection-it,

Thanks for the reply.

I'm glad this is working for you.

Have a great weekend as well

Hi hand-army,

Nice that you explore those.

Here is an example that builds closely to the ideas from above but adds some complexity.
CV4_2025_drs_25_MGrb_21.c4d
The Idea of two Bars in one works similarly to the example above, but it needs more combinations (Child) under the cloner.

If you want to mix single bars in it, please also look here.
CV4_2025_drs_25_MGrb_22.c4d
The Top Cloner is set to Random.

The Voronoi Fracture distributes the initial options for the Material. Note: the Source is off!

Please let me know if you have any questions about these setups.

All the best

Thank you for the reply, room-unit.

This is why I typically ask for a file instead of images. Since I do not have a current Insydium license (Too few questions here to justify it), I did not ask.

My best wishes for your project

Hi diet-commission,

If you re-import the FBX to Cinema 4D into a new file (Merge) to see what was written out, is that the same you get in Unity?

Have you used the cogwheel to specify the export options?
The PLA folder must be on the same level as the FBX file.

If all of that was done, and the results are not OK, please contact Tech Support:

Hi David,

Thank you very much for the reply.

Enjoy

Thank you for the reply, smckenzie.

My best wishes

Hi smckenzie,

Thank you very much for the file, and using Apple-Cloud!

The problem is that there is no simple solution in one go.

With the Correction Deformer, I have created a demo to showcase where the connections do not agree, simple geometry problems, not based on the tools. I have set up two cameras to point them out.
CV4_2025_drs_25_MOif_01.c4d
In the other file
I corrected the problem points but to the disadvantage of the horizontal "beams".
CV4_2025_drs_25_MOif_11.c4d
I hope that makes sense.

Let me know what shape the final object should have, and I try to find a way, but there are limits in geometry and merge shapes logically.

All the best

You're very welcome, chemical-subject.

My best wishes for your project!
