1. Open Cinema 4d, and create a basic abstract render or load one that you have already started. We are going to add onto this render by simply adding some modifiers and editing it to it to give it different looks. This lesson is really just to show you what you can do with your abstracts, and how you can keep making them better. It is up to you to experiment with the settings. You may use everything we show you in this tutorial at once, or just use one of the effects.

2. Ok, first things first. Lets select the Model Tool from our toolbar on the left side of cinema 4d. The Model Tool is highlighted in red:

(Note: if you scroll over the buttons, it will show you the names of each tool in the bottom left of the screen)

3. Now, If you loaded your render from a previous project, chances are its already selected. This is just to get rid of the grid lines on your render if you were just creating an abstract piece. The first thing we will do to edit our image, is apply a matrix extrude. To do this, go to Structure > Edit Surface > Matrix Extrude. Once you click it, this box should pop up:

4. Make your settings for the matrix extrude look like the one I have below:

5. Remember, this is just experimenting, I find these settings to work well for me in lots of my renders, but you can edit them however you want. Click Ok and watch as your render changes!

6. Looks pretty nifty, eh? You may choose to stop here, or we can apply "Nurbs" to our render if you want to continue.

7. Continue? Good choice. I rarely use nurbs in my renders, but they are always good to know about for when you are going for a certain look. Nurbs help smooth out your render in a way. The first thing you will want to do is click Objects > Nurbs > HyperNurbs:

8. Nothing appears to happen, but that's ok. We wont see any effects take place until we apply the nurbs to our abstract. Now, remember that our abstract started from a sphere. Cinema 4D keeps track of all of your objects/modifiers on the right side in your "Objects Tab", which is kind of similar to the layouts tab in photoshop. In your objects tab, you should see two objects. They are Sphere, and HyperNurbs:

9. Drag Sphere into the HyperNurbs Object (Left Click > drag > drop in HyperNurbs). It should look like this:

10. Now watch it morph into a much smoother render. You may not be able to tell the real difference until you render it in the viewport or as a file, but here is what it should look like now:

I'm happy with the way mine turned out! I will probably use this in one of my future works ;)!
