Tuning solver attributes

Now that we've got a basic simulation running, we need to direct it, and…fine-tune it, and make it better.…What I want to show you in this movie is the solver attributes for the nucleus node.…So I have got the nucleus node open already, I have selected my cloth, and hit…Control+A to open the Attribute Editor.…And in the nucleus tab, if we scroll down a bit, we'll find a section that…says Solver Attributes.…And essentially, there are really two main properties here that we can play…with: the Substeps, and the Max Collision Iterations.…

Higher values will give you, quote, more accurate results.…However, just increasing the value alone is not really going to be good enough…to fix problems that you have, but it's a start at least.…These default values are quite low, and if I increase them, what will happen is…the simulation will start running more slowly, because it's working harder, and…allegedly, more accurate.…The Substeps refers to the number of calculations per frame, and with higher…numbers, we will get a slower playback, and it'll actually, in a lot of cases,…
