Analyzing nav mesh resolution
Unreal Engine provides a Navigation Mesh Resolution system that lets developers create mesh tiles at three distinct levels of detail within a single nav mesh. This means that you have the flexibility to generate sets of tiles with high, medium – the default option – or low precision settings. By opting for different precision levels, users can achieve faster generation – in terms of computing time – of a dynamic nav mesh while the game is playing.
Note
When we speak about resolution, we mean the precision and quantity of cells produced to map a specific navigation area.
A high-resolution tile may divide a given area into more polygons to closely approximate its shape. Conversely, a low-resolution tile will encompass the same area but with fewer polygons. This trade-off enables quicker tile generation but may sacrifice some accuracy in the process.
As a first test, we can start analyzing one of our gyms:
