The description of the Light class contains this remark:
Remember also that dynamic lights rely on modifying the colour of vertices based on the position of the light compared to an object's vertex normals. Dynamic lighting will only look good if the object being lit has a fair level of tessellation and the normals are properly set. This is particularly true for the spotlight which will only look right on highly tessellated models. In the future OGRE may be extended for certain scene types so an alternative to the standard dynamic lighting may be used, such as dynamic lightmaps.
Is that remark partly or entirely obsolete? I haven't noticed any problem with a spotlight shining on a coarsely triangulated mesh.
