CINEVERSITY

Hi catch-place,

I invested some time into it. I can't pinpoint what is going on in the file. However, copying and pasting it into an empty file allowed me to cache the file.

I did some changes, instead of deactivating the Rigid Body, I have set the trigger to "On Collision" and used a little cube to push them out.

Next, I explored the idea of moving the keyframes to the start and cache from there, which worked as well.

In the folder below you will find the "pasted" file, cached, but also an Alembic file, merged into a C4D file, so you can test.

There is a "deactivating" mechanic in the Rigid Body, but I was not able to pinpoint it to this in a given time frame (I invested a few hours to test, as the caching of the whole file with higher sampling/step rates took quite a while with my little Mac here.

File:

(Textures not included)

I hope that helps.

Let me know how it goes.

Cheers

Hi MaverickMongoose,

Thanks for the two files.

I rendered a preview, and it appears differently (in terms of timing) from my editor view.

You certainly have different hardware, so I assume your results might differ from what I see.

The timeline being set to All Frames means it provides the next Frame when the one in work is finished. Hence, the preview render as timing control can't be ignored. (Not using all frames will not build up the effects needed here, so the setting is OK, but the amount of data turns off the real-time, at least here.)

Check the Main Menu> Windows> Object Profiler. Run the Scene.
I can see that the Cloner alone takes times of 500+ ms, and if other processes in the background (not Cinmea 4D) kick in, I saw even higher values.

If you have 24 fps, then it easily exceeds the one second that would allow for real-time playback. When the numbers are produced Per Frame, then it is 24 times that duration. Yes, that might not be real-time anymore.

Is this answering your questions?

All the best

I'm glad that fits to your current setup needs, Cit.

Thanks for the reply.

Enjoy your project!

You're very welcome, selection-it.

Thanks for the kind feedback.

Enjoy your project

Hi Geocoy5,

Please allow access to the files.

All the best

Thank you very much for updating this, c4disstanky.

Very nice of you to take the time.

Yes, that makes sense, … memory.

My best wishes

Hi MaverickMongoose,

Thanks for the file. Please take a look to see what happens first. Go to Attribute Manager> Mode> Scene> Simulation> Simulation>
Draw> Enable and Rigid Body Shapes.

Doesn't look good? Correct.

To fix this, go to the Cloner> Transform> Rotation to zero degrees.

Now run the sim again. Should work now.

You might know this, but just in case, you'll get better results if the Collision shape is set to Triangle instead of Auto.

Cheers

Thank you for answering your own question, energy-slide.

Since I don't have a file here, I can't share anything extra, but so far, I can see that you are fine.

Enjoy your project.
