Living in 3D – Blender – Part 3

In part 1 of this tutorial we explored the basics of the free 3D program Blender and in part 2 we started to create an object. In part 3 of this tutorial we’ll explore the options for enhancing our project. If you haven’t read the first 2 parts, make sure to go back and check them out first. Now we’re ready to resume our project.

Step into “Sculpt mode” and pick “Brush”. Then click and drag over the tear surface.

The result should be something like this:

 

Applying the same method on the cube will transform it into a sphere. I will just use the “Snake hook” sculpting tool to deform it a little. Just click and drag its corners.

 

I intentionally overlapped the two objects, in order to show you later the way that reflection works when you render the scene.

Now let’s subdivide the sphere a little bit, to make it smoother.

Go into “Object mode” and follow the same steps as for the cone. You will notice the changes.

It’s time to add and edit some materials to our objects. Clicking the icon that looks like a sphere with two triangles inside will bring up the material properties window. You already saw that any new placed object has a simple material assigned by default. This can be modified in many ways, from setting transparency, refraction, reflection, adding a predefined texture or a photo texture and much more.

 

The sphere shows the current material. Changing the material properties will cause the sphere view to change as well.

Having the cube selected, let’s modify its material. Click on the white rectangle under the “Diffuse” label. Choose a dark blue nuance.

 

Now let’s make it transparent. Drag the scrolling bar on the right until you see the “Transparency” label.

 

Click and drag the Fresnel button and lend button to get the desired result. If you just click on them you will be able to insert the values from the keyboard. For now, do so and insert the exact values I did.

Now scroll down and find the “Reflectivity” label. Insert the same values I did.

 

As a result, my cube has a semitransparent, reflective material. This means that, when I will render the scene, will allow me to see the other objects through it and reflecting them a little.

Now, select the “tear”. Notice that you don’t have the default material window anymore like you did for the cube. That is because you already modified its properties and assigned it for a specific object. You may, of course, copy the material and add it to other objects, but for now let’s create a new one. Click on the “New” button.

 

There you go! The familiar window appears. I just changed the “Diffuse” properties into a yellow nuance. Do something for the sphere, as well.

Now let’s do a simple rendering over the entire scene. Keep in mind that navigating the workspace will not change the rendered view. For this, you must move the camera or create a new one in the desired position. You may select the camera and the light as you do with any other object in the scene.

For now, let’s leave the camera and the light where they are and try to render the entire scene.

Click on the “Camera” button.

 

Now click “Render”. My scene looks like this.

 

These are the very basic steps inside Blender’s secrets. It’s a powerful application, which could help you learn a great deal about 3D design.
