Okay, right, I haven't thought about that... would mesh combining come at a reasonable cost to do multiple times in a short span of time? Would the resulting combined object be drawn in one call?

Thanks for the hints

a combined mesh would be done in 1 draw call - and yes, it's possible (assuming your meshes aren't too large). you may be better off combining small batches of them instead

Okay, now I have a small question concerning the combine mesh.

I have now the following script:

if (Time.time >= nextCombine) { // combine the terrain with the debris lieing around

    var meshFilters = GetComponentsInChildren(MeshFilter);
    var combine : CombineInstance[] = new CombineInstance[meshFilters.Length];
    var index = 0;

    for (var i = 0; i < meshFilters.Length; i++) {
       if (meshFilters[i].sharedMesh == null) continue;

combine[index].mesh = meshFilters[i].sharedMesh; combine[index++].transform = meshFilters[i].transform.localToWorldMatrix; meshFilters[i].renderer.enabled = false; // index++; } GetComponent(MeshFilter).mesh = new Mesh(); GetComponent(MeshFilter).mesh.CombineMeshes (combine, 0, 1); renderer.material = meshFilters[1].renderer.sharedMaterial;

    nextCombine = nextCombine + garbageCombineInterval;
}
