(5:42) Object-space maps can be mirrored ([wiki:Self:Normal_Map#OSNM why])

(6:10) Mirroring isn't always flawless ([wiki:Self:Normal_Map#M why])

(6:45) 90 degree angles aren't bad since he's using a projection cage instead of a distance-based raycast ([wiki:Self:Normal_Map#SGAHE why])

(9:39) In-game vertex count for a hard-edged model is not more than a bevelled model ([http://www.ericchadwick.com/examples/provost/byf2.html#wts why])

(11:00) UVs aren't good because some seams are overlapping ([wiki:Self:Normal_Map#UB why])

+[http://cg.tutsplus.com/tutorials/autodesk-3ds-max/how-to-bake-a-flawless-normal-map-in-3ds-max/ How to Bake a Flawless Normal Map in 3ds Max] <<BR>> is a great overall introduction to normalmapping, but there are a few corrections to make:
-(5:42) Object-space maps can be mirrored ([[NormalMap#OSNM|why]])
+(5:42) Object-space maps CAN be mirrored using special shaders, but requires specific support for the feature which is not too common. ([[NormalMap#OSNM|why]])
 (6:10) Mirroring isn't always flawless ([[NormalMap#M|why]])
-(6:45) 90 degree angles aren't bad since he's using a projection cage instead of a distance-based raycast ([[NormalMap#SGAHE|why]])
+(6:45) 90 degree angles aren't always bad since he's using a projection cage instead of a distance-based raycast, however hard surface/mechanical models generally require smoothing and UV splits at sharp angles unless the tangent basis is synced between baking program and renderer. There was no mention of the tangent-basis issue as the tutorial was created before the topic was common among artists. ([[NormalMap#SGAHE|why]]) ([[NormalMap#Tangent_Basis|why]])
 (9:39) In-game vertex count for a hard-edged model is not more than a bevelled model ([http://www.ericchadwick.com/examples/provost/byf2.html#wts why])
-(11:00) UVs aren't good because some seams are overlapping ([[NormalMap#EP|why]])
+(11:00) UVs have some overlapping seams, no mention of edge padding issues or designing your model for normal mapping. ([[NormalMap#EP|why]])
