Preparing Blender's Units
Even though we are working with virtual 3D objects in 3D computer graphics, they still need to have an accurate scale (based on the scale/dimensions of real-world objects). This even applies to made-up things, such as the robot drone we will model in this tutorial.
3D software such as Unreal Engine calculates lighting and physics based on the scale of 3D assets. Another reason is that when you are building virtual 3D movie sets, it is a good idea to have a standardized scale for all your 3D assets—this way, it will make it easier to place them because they will have the correct size in relation to other items in the scene.
The scale of the scene and all the assets therein are set by using Blender's Units menu. Let's go through the steps to set up Units, as follows:
- In the Properties panel, find the Scene Properties icon, as highlighted in the following screenshot. Click on this icon to open up the Units drop-down menu. Inside...
