With Field Forces in Cinema 4D R21, expect an entirely new experience working with dynamics, cloth, hair, and particles. --------------------------------------------------------------------- Auto-Generated Transcript Below 👇 EJ Hassenfratz (00:00): With every new cinema 4d release, there's always one feature that seems to fly under the radar. And I feel like field forces is that powerful new feature instead of a 4D R 21 that everyone's going to be raving about. Let's go and check out field forces EJ Hassenfratz (00:27): In this video, I'm going to break down the new feud forces in cinema 4d, R 21, and show you how it can completely change the way you work with dynamics, cloth, hair, and particles. Now, if you want to follow along, there's going to be some project files you can download in the description of this video. So what the heck are fueled forces, where if you go to your simulate menu, you see all of these old, uh, particle forces that we've all grown to know and love. And there is our field force. Now, basically what a field force can do is allow you to use MoGraph fields to control the direction of particles or even control dynamics, cloth, hair, uh, all kinds of stuff. So what the field force essentially is, is all of these old, uh, field or old, all of these old particle forces wrapped into one. EJ Hassenfratz (01:18): So let's go ahead and add a field force source scene. Here's an emitter that is just a flat a line. Basically you can see that the emitter is a size of 625 and the X, and then we're just birthing a whole crap ton of particles, a thousand, uh, being, uh, emitted there and a speed of 300 centimeters. Okay, so let's go ahead and let's start using fueled forces to manipulate these particles. So field force has a few different settings here. One is to just add to the velocity of whatever object you have currently flying, whether that be particles or dynamic objects. Another one is to just set the absolute velocity so you can actually set the speed and it's going to maintain that speed throughout the entirety of the movement. And then you can have different fields, help particles or dynamic objects, change the direction, not contribute to the motion at all, just changing the direction of that. EJ Hassenfratz (02:20): So let's go ahead and use some fields to help change the direction of this object. So, uh, you might be wondering, well, what is the, uh, wind, uh, particle force here, uh, that we have here when basically what wind is, is a linear field. And you'll see that when I added a linear field to my list here, you can see we have the linear fall off and you can see all these little dashes here, what those dashes are, are vector lines. And they determine the direction in which a particle is flowing. So you'll notice if I move this up and down, you can see that all of my particles are actually moving this way, the way the, the actual fall-off is facing. Okay. So let's go ahead and let's change the direction to this is facing in the positive Z. Let's go ahead and do the positive Z here, and you'll see that actually the positive Z is shooting all the particles back the other way. For the full transcript visit:
