If you paint a grid with a brush prefab it doesn't use prefab's rotation, instead it uses m_Rotation which is set to default and ignores the rotation.

m_Rotation stores the rotation of the brush which can be changed using the rotation hot-keys. This will always override this stored rotation.

We could keep both rotations with the following code:

Suggested change
m_Rotation = Quaternion.Euler(m_Prefab.transform.eulerAngles);
m_Rotation = Quaternion.Euler(m_Prefab.transform.eulerAngles);
Suggested change
m_Rotation = Quaternion.Euler(m_Prefab.transform.eulerAngles);
var rotation = Quaternion.Euler(m_Prefab.transform.eulerAngles) * m_Rotation;
if (!existPrefabObjectInCell)
{
base.InstantiatePrefabInCell(grid, brushTarget, position, m_Prefab, rotation);
}

Would this be better and still suit your use-case?
