Written Tutorial
Christopher Gruber Visual Effects Artist Lightning Rod Studios Http://www.lightningrodstudios.com This tutorial assumes that the reader has a basic working knowledge of Cinema 4D, and navigation in a 3D environment. The construction of the room, employment of lights, materials, and camera are quite similar in C4D (and most other 3D programs). You should be able to follow Andrew’s tutorial for the construction of the scene fairly easily. In order to create the vines in C4D you will be using the following: ‐Splines ‐Sweep NURBS We will begin by creating the basic shape of our vines. You can either use free form splines, or cycloid splines. Both can be selected from the spline menu on the top of the screen (noted by a blue squiggle with a plus sign attached.) You can also get some pretty nifty looking vines by playing with the flower spline preset, etc....But let’s keep it simple. I would recommend using free form splines as the appearance of your vine is much more customizable. So. Begin by creating a curvy and somewhat twisted looking free form spline. You may want to drag the points along the spline around on the X, Y, and Z in order to get the look you are going for. Next you are going to place a circle spline on the grid somewhere near the free form spline we just created. Now, you will use Sweep NURBS in order to create the basic vine. Do this by selecting Sweep NURBS from the nurbs menu. (green cube) You will notice that nothing happened. In the objects list, parent both of the splines that were created to the Sweep NURBS. If you get something goofy looking like this: Don’t worry you just have the splines parented in the wrong order. The circle spline must be positioned above the free form spline. This is because the circle provides the shape for the vine and the Free form spline is the path that it will follow. Done correctly, you should have something looking like this: Now, creating multiple vines is rather easy. All you need to do is clone the vine and offset the new ones in 3D space a bit. (On the X, Y, and Z) You can adjust the thickness of the vines by scaling each of the circle splines (now found within the Sweep NURBS since they have been parented.) 5‐7 vines of varying thickness will do the trick: You can now individually move, scale, and rotate the vines so that they vary in appearance. I would also suggest going back and moving around some of the points on the original free form splines to help make them look a little bit different. You will have to play around with moving the points, and rotating the splines to get your desired effect: Heres the fun part….animating the vines. Select one of the Sweep NURBS from within the null object. In the attributes menu (under object properties) you will see: Start Growth and End Growth. Lower the End Growth Rate to 0% Place a key frame at 1. (control click the little circle to the left of End Growth) Move ahead in the time line. Change the End Growth Back to 100% Place another Key Frame. Play the animation, and you now have your first animated vine. Next you will want to copy the key frames from this Sweep NURB and paste them to the others. You can also try offsetting the key frames a bit for each of the vines to make them grow at different rates. ....And there you have it. Animated vines in C4D. Here is a test render that I did using a basic aluminum shader. (Found in the Content Browser.)
