What is Lighting?

Lighting is a very important topic in rendering, standing equal to modelling, materials and textures. The most accurately modelled and textured scene will yield poor results without a proper lighting scheme, while a simple model can become very realistic if skilfully lit.

Why would you use it? 

People use lighting in order to make their object more realistic and easier to see. It also makes your object better looking in general. You also need lighting in your scene if you wish to create a rendered video or image.


Different types of lighting

Point light:

1. In order to do this you must press shift + A and select lamp then select point then place this light somewhere on your scene

Sun light:

1. Repeat the same process that you did for point but this time select sun, you should try place this light up high and at an angle to your object in order to get a good effect

Spot light:


1. Again, repeat the same process except select spot, you should place this above your object in order to get the desired effect. This light emits light in a cone like direction

Hemi light:

1. Same again, repeat the process and select hemi. This is a 180® directional light which emits light downwards

Area light:

1. Same steps again just select area instead. This is an upward light that emits light from the plane.

How to effectively light an object in blender

1. Press F12 for camera perspective

2. Then open up the world tab and tick ambient occlusion

3. Turn ambient occlusion to full

4. Reduce ambient occlusion to 0.5

ambient occlusion 0.5
half ambient occlusion


5. Go to the Gather column in World tab

6.  Adjust samples to preferred amount of samples. This makes the picture more realistic but my recommendation is not to go over 10 as it may crash your computer

7. Press 7 for top view

8. Then duplicate the lamp by pressing Shift + D and place lamps at the front, the back, and the side

9.  Then adjust the energy on both duplicate lamps. To do this you have to go to the object data tab and adjust the energy settings

10. Set the lamp behind the object to 0.8 and the one beside it to 0.5

11. Once this is done press F12 and that is the lighting of the object done.
