Hi,
I'm trying to make a simulation cache like bullet time at the movie matrix. It is started as normal speed and then turned to very slow motion.
Do you have any good workflow to do that?
I tried to use "time scale" but it seems not to be animated and is not in Maya beta yet.

Hi dai,

Unfortunately, this functionality is currently not available.
However, it is very high up on our priority list and we are working on enabling this feature in the near future.

Cheers,
Sebastian

Hi Sebastian,
That's a good news!
What you meant "this functionality" was "time scale for carbon for Maya" or "animated time scale for carbon for Houdini"?

Hi dai,

With this post being in the Maya forum, I was refering to the functionality coming to Maya soon.

In regard to Houdini, it is already possible to use animated time scale in Houdini (Carbon Simulation Time Scale parameter)
However, we will most likely improve on this implementation later this year, as it does not automatically deal with animated geometry.
For example, if you slow down the simulation, you would have to manually slow down any incoming animation to match the Carbon Simulation Time Scale.
Because, otherwise, your Neo will have slow-moving clothing and bullets, but his body will still move in normal speed, which is obviously wrong.
I have attached a simple example in Houdini for you. But as I said, be aware of any incoming animated geometry.

Cheers,
Sebastian

Hi Sebastian,
Thank you for your reply!
I misunderstood about time scale problem we faced in Houdini. Our animator made time-warped character motion and export it as an alembic cache. Then our sim guy put it to Houdini and animated "time scale" of the carbon sim node to make it fit the result. He said there were some kind of "shock" on cloth surface after changing time scale.
Your sample scene looks fine and I don't know details of our problem that much. I'll ask our sim guy to come this forum...

For any Houdini related technical questions, please use the www.numerion-software.com/index.php/foru...cal-creative-houdini forum section.
