Caching and refining the simulation

…As you may recall from the movie, Building Constraints and…Belts, a non-cached cloth simulation can run slowly in the viewport.…Here's what I mean.…So when I hit play, we're not getting the greatest of results when we play back.…So, there's a way to fix that.…We'll click on the cloth tag, hit cache, I'm going to hit Calculate Cache.…What Cinema 4D is doing is it's writing out a temporary file…that it can read back in for better results in the viewport.…Now you will see it slowed down in a couple…spots, but overall we get much better feedback in the viewport.…What this enables us to do is adjust the cloth simulation, and do that much faster.…

So, let's click our cloth tag.…And let's go to the tag tab, and let's adjust some of these properties.…There's a couple spots in the flag I'd like to smooth out a little bit.…So, let's take that stiffness down to 10%.…And we'll lower the flexion down to 5.…I don't want those springs to have as much of an effect.…I want the flag to bend more and not be as rigid.…So now let's go back to the cache tab.…
