The idea of this tutorial is to learn to face a complex project. A vehicle is a nice object to use to test yourself and find new problems.
First, we must understand that a project does not reproduce the real world; a project shows an idea or thought and will result in a final image or video. Whatever does not appear in the final result is unnecessary to include in the model.
What vehicle should we make? Let's go with the classic jeep. This will allow for a lot of doodads.
Let's decide what objects of the jeep model will need to be made - body, wheels, seats, and a rocket launcher for good measure. Objects we can ignore include the engine, which remains hidden under the hood. There are many additional objects you can make such as a steering wheel to customize your jeep.
