Cached Simulation not the same on different machines

[statement-language]

Hi all,

Unfortunately, this was a project I did awhile ago (over 6 months ago) so I don't have the samples handy, but we had an issue where a scene I'd animated doing a cloth simulation of some paper being blown in the wind was nailed down and cached, but my employee's machine saw the simulation behaving differently on his machine than on mine. If I played the file on my machine, the simulation was cached and played correctly. If I played the file on Michael's it played differently (though I think it was also reading as cached on his too). I'm pretty sure I saved the cache to the project file itself vs externally and I'm pretty sure I used C4Ds built-in cloth sim engine. It would have been on C4D 2023 I suspect though.

Just curious if anyone's had that or a similar issue.

Hi Ryan,

If it was internally cached, the file size must be much larger just to give you an indicator.
If cached, the results will be the same, AFAIK; otherwise, we would have many posts here from render farm results and jumping frames.

Caching cloth, to my understanding, is point-based; there is no derivation.
If you would like to test this, write out an Alembic file and load it into the Cached file as a "reference." It is highly unlikely that both change in the same way.

Since it is easily imaginable that I do not have the two setups that cause your trouble, please get a second opinion on that, meaning get in touch with Maxon's tech support at

(It might take longer this week as we have a company-wide meeting.)

All the best
