Subtitles of the Movie

So with this movie we'll look at those two remaining categories we haven't taken a look at and those are Dynamic Groups, and then the Decorated Groups. The first thing we'll take a look at right here is the Dynamic Groups and you might ask yourself well, what are those and why would I care? Dynamic Groups is a very cool feature that allows you to add different cloth behaviors to the same cloth object. You can have different dynamic qualities across the face of your cloth object. Now the need for that may not be immediately apparent, but think of something like a trampoline where you've got somebody jumping right where there feet are, the trampoline goes down very abruptly, very quickly. The fabric of that is stretching quite tremendously there, but then it rapidly kind of spreads out the amount of stretch to the rest of the surrounding cloth. Well, that's a perfect candidate then for the Dynamic Groups. So what I've done is I've created a Choreographed Group. If I say, oh, let me get out of Edit Constrained, or come back here to Choreographed, I've already selected the sides where the springs would attach as a choreographed group. I don't want those things to move. I want them to stay the same. So to add a new Dynamic Group, just like anything else, you would go New Dynamic Group, go ahead and give it a name and I'll say, Max Stretch, OK; and then, let's add another group. I'll say another New Dynamic Group, and we'll say, Soft Stretch, and select OK. Let's edit these groups now. With our Group Editor open, I've got Soft Stretch selected, but I think I want to come back where it's just a little bit to Max Stretch and select an area, not quite in the center, but where we could have a character standing, and it highlights those, and that's our new Max Stretch. If we click back through we come back to Choreographed, we see those, and again, these areas are already pre-built, they just don't have anything defined, which is what we're doing here, except for those new areas that you need to add when you're working with New Dynamic Groups. So now we've got Max Stretch handled, go ahead and do Soft Stretch, select an area a little bit larger, maybe we'll add some to that here. Remember I talked about not overlapping some of your groups. Well, this is a case where we've got our Soft Stretch built in there and I might go ahead and add some little fingers of that coming off, knowing that the cloth material is going to behave a little bit differently right there, and then I'll say Remove a Group. And you're not actually removing the group, you're removing the selection the group is creating for you, and that would be Max Stretch. So doing that, and there we get a little hole that pops up there, and I didn't see that occur there, so I am not sure why. Don't you wish software worked perfect all the time? It doesn't. So what I'm going to do is carve out this little area here, then I'll ask this to show us Multi-group Faces. According to this, we don't have any. So let me cycle back through. We've got our Soft Stretch, our Max Stretch disappeared when we drew over the top of it, so it is performing a little bit differently than the polygon selection, so I'd better add our Max Stretch back in. And we'll do it just like that. So now when we go to our Soft Stretch, that's there; Max Stretch is in between; and I would tune this up a little bit more so they could be adjacent. The tool just doesn't perform the same way it does with polygons. But now, let me go ahead and exit the Group Editor, and go ahead and rotate our scene a little bit here. If we went ahead and calculated a Stretch on this or a Drape, we would go ahead and see the center section go down just a little bit more. So let's come back to our simulation settings, and say let's drape this thing 10 frames. Let's see, we don't need to worry about Cloth Self Collision, I'll just say calculate Drape. There we have it. We can see everything draped the same way. It's this perfect concave shape there. Well, that's because we didn't select any of these other areas right here to make a difference. So let me go ahead and clear Simulation, and come back here to our Dynamic Group. We've got the Default settings, we've got Max Stretch, and I'm going to say Sheer Resistance on this, let's take that down to 10; Stretch Resistance, I'm going to say zero. Then for our other area, Soft Stretch, I'll say Stretch Resistance instead of 50, I'll say, well, let's make this 30, and let's go ahead and calculate Drape again, using the Simulation settings. So here we are. Now again, a little tweaking is in order. We have, you can tell, just a little anomaly here where the Max Stretch is and I would want that to be more significant. But instead of taking your time tweaking this up, I wanted to let you know that this is how you can create some different dynamics in the same cloth body as you work with it. The last area to work with are some that are really designed for folks that create clothing. If you're not actually creating clothing for Poser you probably will never use these things because it's just a little more complex to use, but here's what they are: Soft Decorated Groups, and Rigid Decorated Groups, can occupy near the same place, but it's where you want something that has a soft to dynamic to behave on it's own but follow other soft bodied items. And you're thinking, What kind of thing would do that? Try thinking of a belt loop where it might bend and flex as the waist moves, but it remains firmly attached to the underlying cloth object around it. That's a perfect candidate for creating a new group from the Soft Decorated Group right there. The Rigid Decorated group would be for a piece of clothing, say your character is a businessman and has a tie on. Well, the tie itself, the part that hangs down in front of them, can blow around in the wind, but the cloth part that makes up the knot of the tie near their neck, is not going to move at all. It could also be a belt buckle, where the belt flexes a little bit but the actual metal of the belt buckle doesn't. Well, that's what a Rigid Decorated Group would be. So they all work with the cloth, they all behave a little bit differently, the Soft Decorated and Rigid Decorated allow you to control how aggressively those dynamics interact with them, and of course, as we look down at the new and different dynamic groups you can create to have one piece of cloth behave with different patterns.
