I have an issue related to this topic:
In short, if I use a 3D GridMap with a meshlibrary composed of Meshes ONLY, the loading of the map is superquick (i´m talking about hundreds of thousands of mesh - if not millions- in a few seconds).
If I go with a meshlibrary composed of StaticBodies (i need them to detect the click of the mouse on the object placed on the gridmap), a simple 10 thousands bodies map will takes several minutes to load, a 50k bodies map will take up to 15-20 minutes.
Point is I was expecting a slow down of the performance, but one would expect adding physics objects would impact mainly on the frame rate, but that´s totally untrue: the framerate remain basically untouched.
I would like to know where this slow loading time came from, why does a static body take more time to appear on the scene than a simple mesh, even before any physic is involved?
