Regarding the required shine of certain objects like sword blades, metal helmets etc.
My recomedetion is to make the required shine when you add the object's layer in your texture.
Then inorder to avoid unwanted shiny effect for other objects like the shields in post 46 ALWAYS make the normal.map.texture's alpha chanel BLACK.
Take a look of this picture:
How shiny the helmets or the swords blades are looking determined by two factors
a) How much shiny i made them in the texture and
b) from the battlemap lighting.
Many people select spesific areas like blades in the normal.map.texture and make them versions of grey. But in my extended expirience by playing all battles in varius battlemaps , such option may end up with a totaly shiny like a "devine" sword or spear blade of a shiny helmet that shine its self covers all texture details.
So this is my humble advice.
When you add a sword to a texture, select its blade and play with contrast and lighting , even in color. When the result is what you like create your texture's normal.map with its alpha chanel totaly BLACK.
That ensures that textures show 100% the colors and shine you wanted and selected.
