CINEVERSITY

Thank you very much,

I mentioned the time here that I tried to see all (?) variables in this "game", and explored a few. (Like placing the position change into a Color Vertex Map, while using a range mapper to tame the results, then using this Color Vertex Map to drive the Displacement. The model exploded here and there 😉

Time is one part of the game, but my main idea is that a problem comes back until it is solved. Sadly, with the forums 1-3, around 15+ years have passed. Since things change, that is not a problem, as more experience will lead to different outcomes.

However, sometimes I can't solve things, and the developers have to do it inside the code and provide a solution, whereby I can only share a process or workaround. The idea of having it solved in the app sounds to me more teamwork-friendly.

If you have any XPresso ideas, but something is missing, perhaps a little piece, I'm happy to look into it. Often, questions like yours need some "storage" to keep data for a moment. In the past, I used a copy of the model; these days, I add the Color Vertex Map into the mix. Perhaps the Joints can be a good driver in this case…

Anyway, sorry for the longer text, but your kind reply made my (Sun-)day. Thank you for that.

Enjoy!

THankss for the reply, steal-shelter,

Fingers crossed it provides what you like to have.

Thank you for the question!

Cheers

Hi philosophy-chemical,

Please have a look here:

Add your vote please.

In my private opinion, it seems like something Apple needs to address. Yes, there could be a workaround, but that might be eliminated when Apple fixes it. Meaning, all previews set up with an app based solution might miss the images then. This puts every non-Apple developer in a difficult position.

Yes, having no solution after so many months is annoying; I agree.

My best wishes.

Hi AlexC.,

Yes that IOR. To calibrate the "Lens" I would set a camera straight to the image and far away, with a 500 or 1000mm focal length. Then dial the IOR until the image is close to the original (meaning it is not stretched and does not contain parts of the other image).
(Image below shows too much magnification)

Yes, three is possible, with three stripes and a higher IOR. Three stripes means slimmer stripes and more magnification. Here, the feeling of these Lenticular Postcards becomes more apparent, and its imperfections deliver that feeling even more.
If these artifacts are too prominent, then the lens needs to be smaller, or perhaps shaped differently

Here is a snapshot from a postcard I bought in the spring while visiting Germany and the Filmmuseum in Frankfurt. If I'm not mistake it has five images in use. This also demonstrates the analog artifacts of this technique very nicely. In my opinion, perfection here would ruin this.

I assume that the aesthetic of this effect should be evident, if it is just a blend of images, which could be done faster, as mentioned above.

Example with three: (Images for demo use here only)

Hi nopopoch,

Thank you for the file and the care in the file.

To have two objects "cap" to "cap" connected via a Connector is relatively close, not like superglue. Perhaps not what you expect, at least that this will get anywhere near what I get from the text bubbles above them.
Suppose they were 100% like a belt, a stretching object would have an influence on the connected part. Which needs to go in both directions, and enable a Feedback loop. That is my observation so far. Below are a few examples, with or without animation. Please mess around with them to see how some parameters influence the results. Yes, the documentation could have a table with all combinations and interaction results.

It tells, like for the Rigid Body, what to expect with the Connector.

The question would be, why split something that needs to work anyway, like one object?

Here is an alternative, just joints turned into Dynamic via IK tag, since your file showed what you like to have, but no context, this might work, or is completely off.

I'm not sure if I was of any help here; a little bit more context might help me.

All the best

Thank you very much for your reply, atomician.

Hi Gloria,

This is a new question, which should be in a new thread, otherwise, people looking for a specific answer have to read through perhaps related but not targeted information. Thank you for considering it in the future.

My computer would not even start, and gave me an Alert.

From a general observation: There is the idea of just placing Simulations on things, and all is solved while it stays fast and stable.
The number of parts and details the conveyor belt has in your example is quite large. When the object comes in the hundreds that need to be calculated, it will take a lot of computer power, but also with the increased complexity derivation from the hoped result will show up earlier. Also in general terms, more often that place a Sim on things works. So, the artist is required to decide when to switch to a dual (split in technical and visual) set up.

For 3D animation, from my earliest hands-on classes, I tried to help people overcome the idea that what you see is what needs to happen in the Scene. That is cryptic when shared in that short way. For your project, being a very detailed animation model, I would suggest splitting the animation into the simulation.
As in the first file, I used a proxy for the editor view to give a reasonable playback speed for the Scene. For the rendering, the fully detailed part was then used.

Here I would leave the animation as is and reduce the Conveyerbelt to a single Plane object, animated in the same way, so you could even connect the Offset values from one Spline wrap to the second, right mouse click (RMC) Expression> Set Driver, second instance RMC Expression> Set Driven Absolute.

Next step, the Scene scale is important for the simulation to be more optimized. Your objects are small. So I used the Scene> Simulation> a small scale.

When you are in the Scene settings, I left the Draw options on, as I used for the Collision Shape of the "Particles", the Box option, which is surely the fastest. (The Draw can be switched off, they have no other function that to inform you.)

The Speed in the Particle Emitter plus the Gravity creates only problems, while moving away from realistic behavior. I set the Speed of the Particles to zero, and switched the extra Gravity off; the Scene Settings have a Gravity setting already.

For the Collider set up, I increased the friction while also setting up a Stick Modifier. Explore what is needed.

The Particle Geometry has a lot of Selection Tags, each will add data to the Scene. Are they all needed?

In short, the Simplified Conveyor Belt has no need to be rendered; it is just needed as information. In this way, you have a stable animation and a fast simulation. A tiny bit more work, but it will save time.

Here is an example

Thank you for you feedback, tear-one.

Enjoy your project

Thank you very much, Mark, for the feedback.

My best wishes for your project!

Thank you very much, Vincent, for the reply 🙂

I'm glad you got your setup running.

Let me know if there is anything you would like to include.

Hi PSCGI,

I believe that doing it reverse is a way to go, as the distribution in the letter is mostly even, as shown in our Quick Tip.

My tip produce Particles inside the letter and animate those in any way you like. Have a multi-segment spline with starting points all over the Object that contains the particles and their movement.

At one point lower the animation force, and perhaps switch off the Collider. While a little bit earlier, start with a Follow Spline. During the start, set Follow Strength to zero, start shortly with a negative value, then slowly increase to positive (Alternative, use the Mix slider, but there is no negative). If the animation looks right, cache it, then use the Time Mapping for the cache, perhaps just right mouse click, and use Flip Horizontal.

The Time mapping also allows for fine-tuning the animation timing, perhaps a good option to get a good dynamic into the mix.

Here is a simple sketch, perhaps that triggers some new ideas.
CV4_2025_drs_25_PAip_01.c4d
and an example with "Mix" and more along the QuickTip, cache it then reverse.
CV4_2025_drs_25_PAip_11.c4d
With cache, etc

Thanks for the reply, Pitichi.

I'm glad you found something.

I have no idea how often those things appear on your screen, but allow me a tip: joints might be more adaptable here to various meshes.

All the best

P.S.: I have had no option to see you file. If that 1MB size hits again, I open DropBox, Wetransfer, Google, Adobe or Apple cloud services. Please always the full URL pasted, no HTML wrapper.
If that is no option, I have a drop box account and I can set up an upload.

You're very welcome, object-kind.

Thanks for your reply.

My best wishes

Thank you very much, earth video,

You're very welcome. 🙂

My best wishes for your project.

Thank you very much for the reply, hand-army,

If you like to dive into the Turtle "coding", here is a quick example.
CV4_2025_drs_25_MGgt_11.c4d

This is different from the Tutorial above. The Tutorial above shows a doubling, but when you look at the base of each "forking", there are three points, which might be used with the MoGraph variables.

All the best

Thanks for the reply, Radiometric.

If that works for you, good.
Why the Alpha is not working would be good to know.
Since you shared no file, please check here with the Tech Support if you are interested in working with it in the future.

Perfect, thanks for the reply, Max M., you're very welcome.

I'm sure you will find some areas to benefit from your adjustments.

Have a great day as well, thank you! (… here, I will call it soon a day 🙂 it goes close to midnight.)

My best wishes for your project!

Thank you, Fettness, for your input.

I hope more people find working with Mocap a rewarding experience. I'm sure with more advanced Architecture Visualization, this kind of work will get more attention to fill scenes with live. Especially people interacting or walking upstairs, etc.

Anyway, in my vision, I see many more artists doing movies, and being able to do it pretty much anywhere is a huge step forward. Something that wasn't even thinkable a decade ago.

Enjoy, and of course, my best wishes for your projects.
