Join Andy Needham for an in-depth discussion in this video Editing and Advanced tabs, part of X-Particles 3 for Cinema 4D Essential Training.
- Editing particles allows for granular control over how the sims is shaped. Let's take a look. Here we have a basic sim with an emitter and some turbulence. If we just pause it here, you can see that some of these particles are straying away from the main shape. So, we could remove those by enabling editing. In the editing tab, let's make the point's editable. You need to mover over into point mode and now everything is selectable.
Use the lasso tool just to grab a few of these particles here. Probably won't get them all, though we can just select and press delete, and we'll grab these guys that think they got away, but they didn't. So, we're going to rewind, and press play, and see what happens. So those have now gone. What we can also do, is move particles around. So, maybe these ones, quite a lot, maybe these ones we just want to shift over.
We can do that by using the move tool, we could even rotate them, pressing M and then I we get the magnet tool, and we can even just sculpt these into the form that we require. Just push those back over there. So, let me rewind and play. Before we do that, you can see that where my mouse is, it might be a bit hard to see from here, but, there is a key frame. So, when we get to that point, or using the blending curve, we're going to see the particles move into position.
If we change the curve slightly, it will just jump, it will be really harsh, so you want blend and ease in the particles into position. There they go. Add you can smooth that off, you just need to play around with the curve. Let's take a look at the advanced tab, and specifically just he random seed. In this system, there are two emitters. If you look at the display settings, one is blue, and one's orange.
Let's rewind and press play, and we can only see the orange particles being emitted. That's because the blue ones are emitting in exactly the same place as the orange ones. If we go into the advanced settings, and we change the random seed, now we can see the blue particles being emitted. This is because by changing the random seed, we're getting a different emission pattern.
It's worth noting the modifiers that rely on the random seed will also be effected by changing this value. So, even if you only have one emitter in the scene, and want to change the look of the result of a modifier, then you would adjust the random seed value. Randomizing the emitter will produce a different look and feel to the emitted particles, which can produce a more pleasing result, and the ability to edit particles allows for a greater level of control over the resulting particles simulation shape. Why not have a play with the settings and unleash your creativity.
