Fusion360 provides a diverse suite of tools for 3D modeling, simulation, version control, and importantly, mesh modification.
Model Consolidation is fairly straightforward when you have an Assembly. An Assembly is a collection of individual components that function as a single design in fusion. Given the Assembly has multiple components, selecting any 2 components and selecting the Combine tool will combine the components into a single component.
Mesh Reduction occurs after model consolidation, as rendering a complex mesh is computationally intensive so it is recommended to only mesh the outside of as few components as possible while maintaining the level of model fidelity you aim to acheive. The process is the same as model consolidation, select the component, navigate to the Mesh tab, and select the correct tool. The specific tool we used is called Reduce.
Using the assets created in the previous step, it is time to customize the drone model in Unreal.
Enter Unreal and locate the AirSim content using the content browser.
Duplicate the default AirSim drone.
Double click to enter the Asset Editor
Select the correct drone model
Adjust blade model pivot points and reimport.
Adjust blade model positions
This step is very involved and if you have not done any 3D modeling before can be very intimidating.
Creating a virtual environment in Unreal consists of gathering Assets to be used in the Landscape.
I do not recommend trying to build a virtual environment totally from scratch, because the complexity required for a decent looking environment can take many hours. Visit the Unreal Asset Store and try to find free or low cost assets for the task of building your own virtual environment for simplicity and efficiency.
