Working with 3D Objects / Working with Modifiers/Parameters pt. 3
Subtitles of the Movie
In the previous chapter, we saw how you need to use the local coordinate system when you are setting an X, Y, Z type parameter for the bend modifier. Let me just quickly demonstrate this with another parameter. Let's delete that bend, go up here and put a noise modifier. Now noise adds random variation to an object. It's often used to achieve a less perfect, more natural look. Let's adjust the strength of this noise modifier in various directions. Let's put a strength of 5 in the X direction, and you can see that the noise distortion is being applied along the X direction. The other directions, Z and Y don't have any distortion. Let’s try putting a ten here for the Y. Now you can see that distortion has been applied in the Y direction and let's try a 20 on the Z. And you can see now that distortion has been applied in the Z direction. Again, we have to refer to the local coordinates system of the object, not the world coordinate system to know how this strength parameter will be applied. The last thing I would like to talk about is the importance of the order of the modifiers in the stack. So let's put another modifier, a twist modifier, on this box. Let's set the angle of the twist to 300 and let's go back and apply this bend in the Z axis. So this is the final result with the bend applied first and then the twist. Let's drag the twist down in the stack, now that's our final result. Let's turn this on so we always see the end result. So let's compare those two. That's with the bend first, that's with the twist first, quite a different result. What's happening here, and it will help to look at the some of the other windows, I am going to hit Alt W, is that the twist modifier is like a tornado, it has a calm center and more forces you move away from the center. So, turn off show end result. This is the twist gizmo and because the box is centrally aligned within the twist gizmo, it gets a very regular twist. From top to bottom, the same twisting force is applied to the box. Whereas if we put the twist on top, what happens is, the box gets bent first and then twisted. Therefore the box is not nicely aligned within the twist gizmo. The lower part of the box is farther from the center of the twist gizmo. It's in a stronger part of the tornado so it gets a much stronger twist as you can see. Now the points I have made in these chapters, though I have only demonstrated them with a couple of modifiers, applied to many, many modifiers, having an adequate number of segments, to achieve the effects you want, using limits, referencing the local coordinate system, when setting the axis parameter for an object space modifier, which is most modifiers, and finally, knowing that order can matter a lot when applying modifiers. ct space modifier, which is most modifiers, and finally, knowing that order can matter a lot when applying modifiers.
