Unity Tip: Agree on Scale

The first thing you need to do on a new project with modelers is to agree on a scale. This is especially important if there are multiple modelers on the project, you don’t want them all producing content at different scales! The best way to determine scale is to ask each modeler to produce a one unit cube as they see it. Bring the cube into Unity and compare it to the primitive Unity uses (Menu > GameObject > Create Other > Cube). The Unity cube is one unit squared and one unit is one meter.
Why is it important that we stick to Unity unit = 1 meter? For starters, it just makes sense right? When you code anything in your game, it’s easy to move something 1m/s.
Also, if there is any physics in your game, you’re going to need to stick to this concept. The physics simulation is based on 1 unit = 1 meter and any other scale is going to give you a physically weird world. Things will fall too quick or slow.
