Lemon Slice Tutorial: Part 3 - Lighting 

Before we add the final touches to the lemon project by cutting it in half and animating it, I thought I would make a brief post on lighting. Lighting is an important part in the making of 3-D objects as it helps them come to life by adding natural light which is then reflected off the object to lesson that uncanny valley kind if feeling (https://en.wikipedia.org/wiki/Uncanny_valley). 

Now first off we are going to create a point light. A point light is a node of natural lighting you can place anywhere near your object to make a source of light display near it. First of all, click on the create tab that the red circle is highlighting in the above picture. Once clicked, click on the part labelled "Lights" and select the point light, this will add a point light into your scene, now press 7 on your keyboard to enable the use all light option. If you want to move around the light node you can click the move tool (inside the blue circle) to move the light node and cast shadows on different points of your object. 

The next step is fairly simply, use ctrl + D on your keyboard to create a duplicate of the first node you created, move that node to what ever position you desire and play around with the settings on the right if you want to change how the lighting works. 

For the final step click on the create tab again and select lights just like in step one but, instead don't click point light instead click ambient light. Now the light will at first be far too strong so change the intensity setting (marked with the red circle) to about 0.1 give or take. With that done your free to move around the nodes until you have the exact lighting you want on the lemon object. For the next tutorial I will show you how to split the lemon in half and apply a face to each side.
