I was recreating a small city in Unity3D and was going to place streets and pathways according to a sketch. I'm building for Android and the city is quite small; I'm planning to have the entire road mesh(es) loaded during play, without a load/unload algorithm. I made a few road meshes in Sketchup and imported them into Unity, but was unsure on how to manage them. I thought of two strategies but was unable to identify the pros and cons of either:
Place all the separate road meshes in Unity and position them, recreating the sketch and make them children of an empty GameObject to order them in the Editor window.
Create the entire city roadmap in Sketchup, making it a single and complete mesh. Then, import it into Unity and that's it.
The city is quite small and I'm planning to have the entire road mesh(es) loaded during play, without a load/unload algorithm. I'm building for Android.
Which strategy should I prefer in this situation? Or are both basically the same?
