Mesh.RecalculateBounds

Questions & Answers

The documentation for the function contains this comment…
“Assigning triangles will automatically Recalculate the bounding volume.”

Experimentally I am seeing differences if I manually call this after assigning triangles?

mesh.triangles = newTriangles;
Bounds b1 = mesh.bounds;
mesh.RecalculateBounds();
Bounds b2 = mesh.bounds;
if (b1 != b2)
{
	Debug.Log("Bounds "+b1+" => "+b2);
}

Bounds Center: (19.5, 0.8, 19.5), Extents: (28.1, 0.8, 28.2)
=> Center: (19.5, 0.8, 29.4), Extents: (28.1, 0.8, 38.0)

Is the documentation incorrect, or am I mis-understanding something?

The documentation is probably out of date. I would personally always call RecalculateBonds (and RecalculateNormals) to be sure everything was fresh and correct.
